Mass Spectrometry Card Hunt!

With my Bohr model cards being a hit, I wanted to create something fun for mass spectrometry. Unfortunately, some mass spectra are hard to find or not labeled exactly the way I want, so I made my own. I used a Google spreadsheet to input the percentages for each isotope, then added the graphs. The resources I created are here:

And the rest of the post is a summary of how I used them.

The Lesson

I started with a pretty standard lecture on mass spectroscopy: what it is, how the machine works (suuuper basic overview), what a mass spectrum looks like, and how to interpret it. I gave them one example question to work on with a partner. They had to identify which isotope was the most abundant, which isotope had the most neutrons, and then identify the element.

While they worked on this, I spread out my mass spec cards in the back of the room (I have a very small AP class). I printed three copies of each of the 7 cards in this initial set. Why did I pick these particular 7? Basically, I was on a time crunch before I had to teach the lesson, and these were all I got to. It wasn’t necessarily optimized.

I intentionally did not include element names on the cards. That way students could practice identifying the element based on the graph.

Here are some of the questions I asked my students:

  • Find the mass spectrum for the element with the most isotopes. (There were two possibilities: selenium & krypton)
  • What is the identity of this isotope?
  • Find the mass spectrum for carbon.
  • Find the mass spectrum for the element with only one isotope.
  • Find the two mass spectra for elements with an atomic mass of slightly below 80. One is bromine and one is selenium. How can you tell which is which?
  • Find the isotope with the most number of neutrons.

As I asked each question, students walked around trying to find the mass spectrum that answered the question. It got them up and moving, which is always good. It was fun for them, but also fun for me as I tried to think of new questions to ask.

Another idea is to just spread them around and have students try to identify each element.

Full Set(ish) of Mass Spectra

I have a complete set of cards now for elements 1-36. Okay, I guess it’s not “complete” per se, but I don’t plan on adding the rest of the naturally-occuring elements.

I won’t print all of these when I teach this again; that would be kind of overwhelming for students. I would pick and choose the ones I wanted to use and just print those. If you’re planning to do this, feel free to make a copy of the slides, delete the cards you don’t want to use, then print from there.

So, there you have it. Nothing too revolutionary. But it made for a fun way to practice their mass spectrum interpretation skills!

Bohr Model Cards and Periodic Trends Model Exploration (fake POGIL) Activity

Nothing motivates me to create new teacher materials more than a failed lesson. After this year’s first lesson about periodic trends and Coulomb’s Law ended in blank stares when asked to explain why atomic radius decreases across a period, I knew I had to do better for my AP Chemistry students.

Here is what I came up with. Feel free to use any of these resources in your classes!

The rest of this post explores the process of creating the materials and how I used them in class.

Creating the Bohr Model Cards

In the initial lesson, I had students draw their own Bohr models to explain the trends, but their understanding of atomic structure wasn’t at a point where they were ready to make strong connections with these. They could create basic Bohr models, but the process was slow.

Instead of students drawing the models, I wanted them to be able to quickly reference and compare the models, looking for patterns and trends. I wanted something they could manipulate and rearrange. There are other printable Bohr model cards out there, but nothing quite fit what I wanted.

So I created these cards in Google Slides, being careful to make sure the atomic radii (sizes) of each atom is correct relative to all the other atoms (though not truly to scale). With some helpful input from chemistry teacher Melissa Hemling, I edited it to make sure the inner electron shells always get smaller as the number of protons increases. I also color-coded the electrons to show orbitals, and made sure the cards went up to scandium to show one d-orbital electron.

I printed the cards on the “4 slides per page” setting, which worked well. Feel free to make a copy of my Bohr model cards to print for your own classes if you’d like!

With the cards made, next I needed some structure for my students to follow in order to make the connections I wanted them to make.

Creating the Model Exploration Activity (fake POGIL®)

So, POGIL® already has an activity for periodic trends and Coulomb’s Law, but I specifically wanted something to get them using the Bohr model cards. I also wanted a focus on how to explain the trends using Coulomb’s Law on AP free response questions. So I made my own!

Side note: If you don’t know what POGIL® is, it stands for “process-oriented, guided-inquiry learning.” This method of instruction starts with visual models, then has a list of questions that guides a group of students through the process of understanding the model.

Here’s the general structure:

  • Model 1 – Coulomb’s Law – For any of this to make sense, students need a good foundation of Coulomb’s Law, which basically states that a greater charge and a shorter distance between particles results in a stronger attractive force between those particles. I made a diagram of a nucleus and an electron to show this, with an equation included to help students make connections with the mathematical relationship.
  • Model 2 – The Shielding Effect and Effective Nuclear Charge – This basic idea here is intuitive: protons attract the valence (outer) electrons, but inner electrons repel those outer electrons. But the application of this in calculating effective nuclear charge is tricky, so this model guides them through the reasoning.
  • Using the Bohr model cards – Students set out all the Bohr model cards for one period, so they can analyze the trends across a period. They then repeat this for the models down a group.
  • Model 3 – Explaining the Trend – This part explicitly guides them through how to formulate a free response answer on the AP exam. By this point, they have a good understanding of the concepts, but haven’t had to put it all into sentences yet.
  • Model 4 – Ionic Radius – This adds a layer of difficulty because students now have to picture what happens when electrons are added to or removed from a neutral atom. The model here allows them to analyze this easier, and introduces the idea of repulsion within an energy level.
  • Model 5 – Successive Ionization Energies – This is almost its own lesson, but it’s an often-tested concept on the AP exam. Students find connections between boron’s ionization energies and its electron structure, then apply these concepts to another table of ionization energies.
Bohr models of Period 2 elements lined up to analyze patterns across a period. (Page 3 of the Model Exploration activity)
Bohr models of Group 1 elements lined up to analyze patterns down a group. (Page 3 of the Model Exploration activity)

Here is the full Model Exploration activity:

Insights from the Activity

  • Orbitals on the Bohr models – One group had a debate about the colors on the Bohr model atoms, with one student sure that the colors meant something, but no one knew what. I had the group get out the scandium card, note the blue electron, and look at scandium on the periodic table. The lightbulb clicked for them shortly after, with students realizing the color corresponded to the s-, p-, and d-orbitals. These connections between Bohr models and electron configurations wouldn’t have happened without the cards.
  • Shielding Effect and a Misleading Aspect of the Bohr Model – One group had trouble calculating the effective nuclear charge of the atoms because of where the core electrons are drawn on the models. Students asked me, “Do core electrons drawn below the nucleus repel a valence electron drawn above the nucleus?” It was a great question. I told them the Bohr model is just a model, and it’s far from accurate. I asked them whether electrons actually existed where they are in the Bohr model, and they responded by talking about the orbitals, how an electron is constantly moving and can be anywhere within its orbital. This quickly got them back on track with the understanding that all core electrons repel the valence electrons.
  • These can be used for a lot more than periodic trends – In future years, I think I’ll start with these models when we first do electron configurations. No, they don’t show orbitals, but the Bohr model is so simple and helpful, them making connections between the quantum mechanical model and the Bohr model is huge. I’ll use them some for photoelectron spectroscopy (PES) because it shows why the binding energies all increase as protons are added. I think they might also be helpful for basic Lewis structures and helping students see why certain elements tend to form a certain number of bonds. Just look at the number of lone valence electrons on the Bohr model…the element will tend to form that many bonds!
  • Use the POGIL® role cards – I used the official POGIL® roles for the first time, and I think it’s a good structure. It also set some great norms. I got these resources (which are copyrighted, so I don’t share them online) from the book POGIL® Activities for Life Science—Designed to Support the NGSS.
  • This took a lot of class time – I mean, I think it was definitely worth it for this lesson because student thinking was great. But we didn’t get done with all of this even within a 90-minute block. It’s the same critique I have about the official POGIL® activities as well. There’s just not enough time to do all of our lessons this way.

I hope you found this post and these resources helpful! Click here for the rest of my AP Chemistry, Anatomy & Physiology, and Physics resources.

Graphing WASB Titration Curves on Giant Graph Paper

Note: This lesson could totally be adapted for SASB titrations as well. Here’s the lesson I used for SASB this year.

Before Class
(introducing WASB Titration & pH Calculations)

Before my students came to class, they watched this video I made and took notes on this notes sheet. In the video, I do pH calculations at six different points along the titration curve, plotting each point as I go.

It’s…a lot. But the nice thing about using this video is that ALL of our class time on this topic is now them practicing, rather than me taking up multiple class periods lecturing on this.

At this point, my students have seen all the calculations, but not tried them themselves. And they’ve seen particle diagrams for SASB, but not for WASB or WBSA. I also forgot to include the idea of a “buffer region” in the video, so I briefly go over that in class.

Introductory Activity – Michael Farabaugh’s Practice

I started class by having students complete this matching activity in their groups. Farabaugh has a video explaining all of this, but I found that my students could successfully complete the matching section without it. (The writing activity that Farabaugh has posted would have been a challenge though).

The Task – Graphing the WASB Titration Curve

I got this idea from AP Chemistry teacher Rafael Betancourt on the AP Chemistry Teachers Facebook group.

As soon as students started finishing the matching activity, I presented this task (also embedded below), but with considerably less silly fanfare than my SASB activity.

The startup costs for this were about $50 because the giant, 2′ x 3′ pads of graph paper are really expensive. Luckily, we only used four sheets of it, so I’ll be able to keep using the pads for years to come. I got 0.75″ diameter colored stickers, which worked well. I wish I’d have gone with the 1″ stickers though, so they could have enough room to write the ion symbols directly on the stickers instead of relying on the key.

Students got right to work. I imagined they would lay the paper on their lab tables, but all four groups taped the graph paper to their vertical whiteboard. They’ve really taken to the whiteboard format, even when I don’t prompt them to. I love it though; they collaborate super well when at the boards.

The results are below. You can move the slider to compare what the projects looked like at the end of the first day and at the end of the second day. What I love most about this is that it encompassed nearly all aspects of the titration curves: pH calculations, the graph itself, important points like equivalence and 1/2-equivalence, and particle diagrams.

Some great collaboration within this group of two students.
This group struggled the most, but they also had the most challenging titration (WBSA). Still, we were able to address a lot of misconceptions, even if the calculations weren’t quite there.

Student Misconceptions Uncovered

As a teacher, it can be disheartening when misconceptions like these crop up (did I not teach this clearly enough???). But in reality, part of the point of tasks like this are to bring these misconceptions to light, name them, and help students correct them. So with that mindset shift, here are a few uncovered student misconceptions that are worth celebrating.

  • Net Ionic Equation is the same as SASB – One group had their net ionic equation written as H+ + OH = H2O. They had separated the weak acid HA into ions on the reactant side and canceled A on each side as a spectator.
  • H+ included in particulate diagram in the buffer region – HA dissociates into H+ and A as the acid is titrated, but the H+ that is produced is immediately neutralized by the OH, becoming water. A couple groups were including those hydrogen ions. I pointed out the N.I.E. for the titration, showing there were no hydrogen ions produced. It felt wrong to at least one student that there were then fewer ions in the particle diagram, so we talked about how those atoms are still there, but not they’re part of water molecules, which we’re not including in the diagram.
  • Equivalence point pH not in the middle of the vertical section – You can see the mistake in the “before” image of the first titration curve above. The group plotted the equivalence point, then had the graph going immediately up and to the right, instead of continuing upward before curving over.
  • Difference between neutralization and dissociation – One of my groups was conflating the two of these, which led to a lot of difficulty in their calculations. I’m glad we had the chance to get this straightened out, since it’s pretty essential to everything in this unit.


Afterward, I asked a few students if they thought I should do all this next time I teach AP Chemistry. Once student replied that she thought it was worth it, even though it took a long time.

And that’s my main concern. This took two full 90-minute blocks. Overall, I think it was worth it. Between exposing misconceptions, getting practice with particle diagrams, practicing all the calculations, and comparing these curves with the SASB titration curves, there was (hopefully) a lot of learning going on.

Either way, it was definitely better than past years when I’ve just worked through the calculations in front of them and not saved time to practice.

Strong Acid / Strong Base Titration pH Calculation Practice

The Case of the Missing Data and the Dishonest Chemistry Students!

In the past, I’ve lectured on this SASB titration pH calculations, then because of time constraints, students had little to no time to actually practice it themselves. This year, I finally got around to creating a flipped classroom video of how to do these calculations, which freed up time for me to actually have them do something with it!

Before Class
(introducing SASB Titration & pH Calculations)

Before my students came to class, they watched these two videos I made and took notes on this notes sheet. The first video introduces what titrations are and show particulate diagrams at each stage. The second video shows how to calculate pH at each stage of the titration curve. After watching the videos, students had an idea of how to all of this, as well as a record of it in their notes, but…it’s a lot. They still needed (of course) a lot of practice.

This is a video I made back in 2016. I think my video skills have improved a lot since then…

The Assignment
(The Case of the Missing Data & the Dishonest Chem Students)

I immediately started class by presenting this task, also embedded below.

The basic premise is that they had all this titration data from a lab last week, but they lost the Vernier Graphical Analysis file and now have to create some fake data to fool their unsuspecting teacher.

Pretty silly, but I played it up a bit, going as far as putting the base volume on a sticky note in one member of each group’s lab book, pretending they wrote it themselves.

The purpose of this task is to get students creating the titration curve and doing all the pH calculations themselves. Instead of a list of problems, they’re doing the calculations in the context of the titration curve as a whole, creating as many data points as possible in the ~1 hour they had to work on this.

Student worked in small random groups of about 3 or 4 at vertical whiteboards (a la Building Thinking Classrooms principles, which I use in my classes) to calculate the initial acid molarity and the pH of points along the graph.

This group, which calculated the most data points, used the same Before/Add/After table and just kept changing up the numbers. It was a great way to sort of automate the process and get quicker results.


Here are the graphs that each group produced. I was pretty happy with it overall. The first group, at least, could have fooled me with their graph, haha!

This group rocked it. They found pH every five mL, then went back and added some more points near the equivalence point to show how that section curves.
This group did pretty well too. Something went wrong in their calculations past the equivalence point, but we ran out of time to figure out what the mistake was.
This group took the longest, but they at least got practice calculating pH. I’m not sure why they didn’t include the equivalence point pH of 7, but I’ll follow up with them next class.

I’ll definitely do this again next year. The main thing I’ll change is to have them include a particulate diagram at each stage of the titration curve.

Designing the book cover for Malfunction Junction

If you haven’t heard me talk about it enough already, some friends and I made a book! It’s a Memphis-themed anthology called Malfunction Junction: Memphis Stories of Stops, Starts, Wrong Turns, and Dead Ends. You can buy copies at Novel (see photo of Alondra and I posing in front of the display below), and we’ll be signing copies and talking about the book at our author event on January 15th at 2:00 pm.

Also, if you come to the event, we’re going to have a special bonus (scroll to the end of this post to see what it is!).

This post is all about the cover design for the book, which you’ve seen. But the road to getting this final cover design was its own journey of stops, starts, wrong turns, and dead ends.

Pick me! Pick me! Pick me!

In the past few years, I’ve discovered (rediscovered?) my interest in art and design.

So when Daniel (head honcho of this anthology operation) asked if I wanted to work on the cover design, I jumped at the opportunity. I really wanted this project to have an excellent cover, and self-published books aren’t necessarily known for having the best cover design.

I got right to work.

I spent a few hours playing around with different designs and effects with Procreate on the iPad. We wanted to incorporate a map of Memphis as well as roads because of the loose theme of the anthology.

But all I came up with these were these hot messes…

I gave up on the first two midway. The design on the right was a crossroads for me, if you will. I knew the design wasn’t working. But I couldn’t explain why it wasn’t working. I’d reached the frustrating point where my tastes far exceeded my current skill level, and I was ready to give up.

I told Daniel maybe we find someone else to do the cover. I hear $30 can go a long way on websites like Fiverr. But Daniel said he thought we could do this, and that last design wasn’t all that bad. (I still thought it was pretty bad though.)

The breakthrough came when I made the roads as rectangles instead of hand-drawing them. I also got some great feedback from Justin Wells, a former student of mine who graduated at Memphis College of Art and is an amazing artist and graphic designer.

That’s how we ended up with this draft of the front cover. See below for the time lapse of my Procreate file! You can follow along with all my experimenting.

What about the Spine and Back Cover?

The what and the what?



Um, well. Oops. Okay, I didn’t think this through.

Here was the problem. We had a cool front cover, but those roads I made needed to extend over the spine and the back cover (at least, that’s how I wanted it to be). Also, the dimensions were off. Since I had just been experimenting originally, I didn’t pay attention to the actual dimensions our book would be. Making all these changes in Procreate was going to be harder than it would be to start over and recreate the. whole. thing.

So that’s what I did.

That went a little quicker because I was mostly recreating what I had already made before. We added some text on the back, a publisher logo, and all the other important cover elements. You can see in the time-lapse that I created the design on top of the template from Ingram Spark (the printer) to make sure everything lined up perfectly.

Actually uploading this was a whole other ordeal, the trauma of which is still too fresh to talk about…

Okay, it wasn’t that bad. But it involved me fumbling around in Adobe InDesign, Daniel fumbling around in Ingram Spark’s online cover program, and lots of frustration because the process is incredibly convoluted and unclear. But we eventually got it.

Wouldn’t it be cool if we had…bookmarks!?

Rae Harding, a friend and fellow contributor to the anthology, had the idea (and a coupon or something?) to get bookmarks printed. I gave myself a little more creative freedom with these, and I ended up with a design I liked as much as the cover itself.

We’ll be giving these out at our author event at Novel. bookstore on January 15th! Hope to see you there!

I’m a science teacher. Next year, I’m teaching a Science Fiction and Fantasy English class.

I hated English in high school.

If there was one class I thought I’d never want to teach…it’s English. Reading was kind of boring, writing was a lot of work for little gain, and grading papers…no, no, no, no. Yet, here I am entering my 10th year of teaching at Collegiate, and I’m about to teach a section of high school English.

How did it come to this??? Let’s start back in high school…

Reading in High School

We read books like The Stranger and As I Lay Dying and The Scarlet Letter and the play Julius Caesar. All teacher-chosen books, and all excellent works (from what I’m told) of historical fiction literature by dead white men. But not books I was likely to ever get excited about. Falling in love with reading and becoming a life-long reader was not going to happen.

I never once (in high school) got to read a book of my choosing for class. I was a student, but I didn’t get to be a reader, someone who chooses books to read in order to learn and experience new things.

Writing in High School

We wrote research papers and literary analysis essays. I compared Denethor from Lord of the Rings (which I read in middle school…remember, I never got to choose a book to read in high school) to Willy Loman from Death of a Salesman. I made notecards for a research paper on the ethics of stem cell research (I think…I can’t quite remember). Never anything I would want to write on my own. I never saw myself as a writer.

Once, I did get to write a descriptive one-pager. I remember I wrote it about what I felt driving in my truck. I’m sure it was actually over-wordy and full of cringey purple prose, but I had fun with it and other students thought it was great. I was proud of it. I think it’s one of the only things I was proud of in high school English.

To be fair, I had great high school English teachers. Gurnow, Boyer, and Henningsen led their classes well. I have fond memories from my time in those classes, and I gained necessary skills for college. But I think the way English is traditionally taught fails too many of us.

What Made Me Want to Teach an English Class

Fast forward six years. I’ve graduated college (studying engineering so I wouldn’t have to read and write much) and am beginning a career in science education at a great school. Every day, all teachers and students in the building have this 15-minute block of time called R&R to read a book of our choosing. I’ve watched the first season of Game of Thrones on a bootleg website, and I feel a bit guilty about that, so I start reading A Clash of Kings, the second book in the A Song of Ice and Fire (i.e., Game of Thrones) series, and the longest stinkin’ book I’ve ever cracked open. And I love it. I can’t wait to get home each night to finish the chapter I’d started during R&R. I realize that all the books I’d ever really loved were fantasy. I start to think that maybe I am a reader after all.

I just never realized fantasy and science fiction were genres that readers read.

Fast forward another six years, and I get the itch to start writing my own fiction. I start working on a novel (spoiler alert, novels are hard to write). The novel doesn’t happen, but I do start writing some short fiction, entering some competitions, and even get a few stories published (which you can read here if you’d like). I start to think that maybe I’m not just a reader; maybe I’m a writer too. I’ve started developing (as Kelly Gallagher and Penny Kittle would say) my identity as a reader and a writer.

Fast forward another few years to 2020. This past year, as part of a professional development unit at my school, I read The Book Whisperer with three middle school English teachers. Yeah, a strange turn of events that I, a high school science teacher, ended up reading a book about getting students to fall in love with reading. What Donalyn Miller describes in her book—a chaotic classroom full of students reading books of their choice, recommending books to each other, surrounded by thousands of books—was so contrary to anything I’d ever seen. It was what I wished my English class would have been. It made me excited about what an English class could be.

Then rumors emerged about a revamping of high school English at my school. (Credit to Thomas Pillow, Peter Bouck, and Shelia Morgan for pioneering this!) Instead of students signing up for required English 2 or English 3, students would have choices, getting to choose classes like Women’s Literature, Coming of Age Literature, Mysteries and Suspense, or Poetry. Classes would be semester-long, with fiction classes in the fall and non-fiction classes in the spring.

Just as I’d developed my identity as a reader and a writer, maybe I could help students do the same…

So I started dropping hints that I would love to teach a class on science fiction and fantasy, and people thought I was joking at first. I mean, maybe I was. It was ridiculous, but the more I thought about it, the more I wanted to share my love for SFF with a class of nerdy, SFF-loving kids. And here I am, prepping to teach it.

How This Class Will Be Different

For about half of the semester, students will read books of their choosing. So I took my classroom budget from this year (being most virtual all year, I didn’t need to spend that much on science supplies), went to novel. bookstore, and bought a ton of books that I think my students might want to read. They should have plenty to choose from!

The other half of the semester, they’ll read one whole-class novel and one small-group “book club” book. My plan is to read Dawn by Octavia Butler as our whole-class novel. I think it’s brilliant, and Butler is an important author to know. So much to unpack in the book, with themes of colonialism, consent, and what it means to be human.

For book clubs, students will rank their choices from a list of five books. Then I’ll assign their book clubs, and they’ll meet with their small group each week to discuss the book. I actually did this in my Physics class last year, and it went well. I’m excited to try it again with science fiction and fantasy. Aiming for diversity in author and genre, I picked these book club options: The Vanished Birds by Simon Jimenez (my favorite book of 2020), Wings of Ebony by J. Elle, Steelheart by Brandon Sanderson, Cemetery Boys by Aiden Thomas, and The Hobbit by J.R.R. Tolkien (the book that first got me into fantasy).

As for writing, we’ll spend half the semester actually writing in the genres of science fiction and fantasy. Students crafting their own characters and stories, learning how to write narratives and learning to read as a writer. During the second half, we’ll focus on literary analysis.

This structure mostly comes from the book 180 Days: Two Teachers and the Quest to Engage and Empower Adolescents. Highly recommend.

I’ve seriously thought about leaving education several times in my ten-year career. I have an engineering degree, after all. But what keeps bringing me back are things like this. The opportunity to try something new, to break out of the mold of the way class has always been done and into something that might better serve students.

I’ll still be teaching mostly science next year, and don’t worry, I can’t see myself switching over to teaching English full-time. But I sure am excited to talk to students about SFF books and help them learn how to write their own SFF stories.

A Year of Making Science Videos

A year ago, I sat in front of my computer, frustrated and on the verge of angry tears.

The pandemic had become real a week earlier. My school closed its building, and we spent a week planning for fourth quarter “emergency online learning.” It was a fast transition, but one my school did well. We went fully asynchronous for fourth quarter, and so as teachers we were planning lessons our students could complete without real-time guidance from us.

And I returned to a former dream of mine: making excellent instructional YouTube videos for my classes.

I had a little extra time to do it, and I had a real need. It would be the only direct instruction I’d be able to provide to my students for the rest of that school year.

So I paid $50 to upgrade to the latest version of Screenflow, a video recording/editing program for Mac, and proceeded to start recording a video that I needed to post that same day.

The details of what happened next are fuzzy, but I had a really hard time with the program, which was recording laggy, unwatchable video. A few hours into it, I was frustrated, I felt like I was neglecting my family because of all the time I spent failing at video production, AND I just wasted money on a program that wasn’t working. (For the record, I don’t recommend Screenflow. If you stumble upon any of my older videos where I seem laggy, it was recorded in Screenflow, and customer service was unhelpful in solving the problem.)

I was ready to give up on the whole educational video thing. But after Carol talked me down, I decided to give it another try.

Fast forward a year, and I’ve made over 70 videos (mostly for my A&P classes), and the channel has had a ton of growth:

I get way fewer views in the summer, and the dip in January is winter break.

I also hit a particularly important milestone for any budding YouTuber: monetization!

To start receiving ad revenue on YouTube, you need at least 1000 subscribers and at least 4000 hours of watch time in the last 12 months. I just hit that second requirement last week. Today, after applying for monetization, I received this email:

So now when there’s an ad on one of my videos, YouTube only takes half the revenue instead of taking all of it!

Really, it’s not about the money (at this point, I have little idea how much I’ll get from this…somewhere between $1 and $150/month). It’s more about the validation that I’ve made something that others find value in, and I’ll get some small compensation for that.

Most importantly, it’s been rewarding to hear from people who have watched my videos. The messages I’ve received from teachers who watch my videos, teachers who assign my videos, or students around the world who kindly take a moment to leave a comment as they’re cramming for the next day’s test have been incredibly rewarding.

Wherever the channel goes from here, I’m glad I didn’t give up on video production that first frustrating night. See you in the next video!

Curriculum notes from my first year teaching Anatomy & Physiology

A few weeks ago, clearing out some storage space filled with long-forgotten binders of notes from my education classes, PDs, and conferences, I stumbled across my notes from the first year I taught A&P.

What I most remember was teaching myself the content over the weekend so I could teach it to my students the next day. Scrambling, trying to keep up. A friend of mine, Kelly, came to my rescue that year back in 2012 by sharing with me her old A&P binder full of notes she took. It was a freaking goldmine.

Anytime I didn’t know what to teach and what not to teach, I went to her binder. And as I crafted my curriculum that year, I ended up making my own binder of notes. Besides the intro unit, this is everything I taught that year.

If you are a new A&P teacher looking for a starting point, these notes could be just what you’re looking for.

Of course, these notes are not perfect. I taught in a weird unit order because my skeleton model was on backorder from the science supply company. I taught some things I think were completely unnecessary (like having students memorize 25 arteries and 25 veins). I lectured wayyyyy too much, and spent too little time making my students analyze and apply what they were learning.

But, as notes go, they’re not bad. And if you’re lost like I was that first year, they may be just the anchor you need, like Kelly’s A&P binder was for me.

And speaking of first year…here are a couple old photos from my first years teaching!

Class photo! I looked so different back then.
Look at that clueless first-year teacher…

Six Steps to Starting a Podcast!

by Someone Who Has Never Started a Podcast

Have you ever been in a class and wondered, “When will I actually use this in real life? Does anyone even need to need to know this?”

Well, my friend Andy and I are starting a podcast to help answer the age-old question:

“When will I need this?”

And in an effort to Show Our Work, here’s a step-by-step tutorial on how to get to the point where you’re ready to start recording a podcast! (by someone who has not yet recorded his first podcast)

1 – Talk a friend into starting a freaking podcast!

The first step is to get a stupid idea and share it with a friend who might think the idea isn’t completely stupid. And just like the time senior year of high school when Andy told me we should get tattoos, I thought starting a podcast sounded like a thing we could totally do and not regret it later. Here’s what that stage looked like for us:

2 – Make a shared Google Doc.

Great. We knew we wanted to make a podcast. Next question: what the heck will it be about?


No, it won’t be about crickets, but Andy works as a biologist and I studied engineering and work as a science teacher, so we knew we wanted to do something science-y and informative, yet fun. We bounced around a bunch of ideas, and started loading all our thoughts into a shared Google doc.

We’re still loading ideas into the shared doc, refining it, leaving comments…it became sort of our central hub for podcast things. It had sections for potential podcast names, episode ideas, a plan for episode format, questions about recording logistics, podcast hosting platforms, and a ton of other stuff. Here’s an old version of the doc. (Excuse the messiness…like I said, it’s a brainstorming tool!)

3 – Come up with an interesting concept.

Tons of ideas, but we settled on the “When Will I Need This?” because of a few key reasons:

  1. It’s unique. We couldn’t any other podcast answering this particular question. Whereas there are a ton of science podcasts, this idea seemed somewhat novel.
  2. It can be explained in a single sentence. The concept is a pretty straightforward question that takes less than 10 seconds to communicate.
  3. Everyone can relate to it. Every time I share the idea with someone, they get a thoughtful look on their face. It’s like they’re instantly transported back to a time where they wondered this exact thing.
  4. There are plenty of topics to cover. We’ll start with some of the obvious things (mitochondria, cursive, algebra, five-paragraph essays, Eli Whitney inventing the cotton gin (which came up every single year of history class somehow)), but we could really take any topic we’re interested in and turn into an episode.

4 – Make a sweet thumbnail to feel more legit.

I made this in Canva. It wasn’t a necessary step at this point (we haven’t recorded an episode), but it sure makes the whole thing feel more legit and real! I’m sure this will change, maybe even before the first episode drops, but in the meantime it’s a pretty cool placeholder.

5 – Fumble around in Garageband until you have cool intro music.

I’m not a particularly musically-inclined person, but dang it if I can’t teach myself a new skill! Garageband has a steep learning curve, but I resisted the urge to throw my iPad against the wall multiple times and was able to find some pre-recorded loops and finagle them into something usable for a solid intro.

We’ve also considered paying someone on Fiverr to do some music, but free is nice too. Check out the intro music below! (We’ll both be speaking on the actual intro…I was just trying to experiment with how the music would sound with voices around it.)

6 – Record your first freakin’ podcast episode!

We’re scheduled to record our first episode (the powerhouse of the cell, baby!) next Thursday. More updates to come.

Oh! One more thing. Our fledgling, zero-episode podcast is now on social media! Follow @NeedThisPod on Twitter and Instagram!

First Day of Practice

The parking lot of the Glenview Community Center in Orange Mound is lined with campaign signs as my mom rolls my wheelchair to the passenger door of our battered Toyota Avalon.

“This all sounds stupid,” I say, grabbing my legs and swinging them outside the car door.

“Don’t call things stupid. Besides, Trey, you love basketball,” Mom says. 

“I used to. When I could still play.”

My mom purses her lips and raises an eyebrow. I’m busy pulling myself into the chair, so I don’t see her do those things, but I know the disapproving face she’s making.

“Trey, you’re only as disabled as you let yourself be,” she says for the millionth time since I got shot back in June. Like, what’s that even mean? She’s got these catchphrases for everything. It’s her way of avoiding the truth that I can’t do anything I used to.

This isn’t the first time she’s tried getting me back on the court. At rehab last month, she told the physical therapist I used to play ball and insisted I would again. So they made me try shooting baskets at the hospital’s gym. The previous year, I had the sickest crossover on the JV team. Now, sitting down, I could barely get the ball up to the net. When they started lowering the basket for me, I couldn’t take it. I just left. 

The therapist followed us out to the car to tell us about the Memphis Rollin’ Grizzlies, this whole team of guys who play basketball in wheelchairs. She gave us the coach’s number. When we got home, Mom dialed the number and shoved the phone into my hands because I sure as hell wasn’t going to choose to make the call myself. Seeing a group of grown men in wheelchairs pretend to play basketball like I’d just done sounded depressing. 

But here we are.

I hear basketballs dribbling to my left as we enter the community center. Through double doors, guys in chairs streak past faster than I expected. We sit in the doorway and watch them shoot free throws for a bit. Empty wheelchairs similar to mine line the far wall. The chairs they’re playing in look way different, with slanted wheels and this bar that extends around the front of their feet. Practice started thirty minutes ago, but on the phone Al, the coach, said to get here whenever. He’d kept saying I just needed to get in to see a practice. 

“Alright, fellas, back on the line!” Across the gym, a small white man in a wheelchair calls out instructions, blows a whistle. The ten players push hard down the length of the court. At the end, they turn faster than I’ve ever been able to in my chair. One dude even goes up on one wheel around the turn. The coach waves us over.

Coach Al asks about my injury, and I let my mom answer all his questions while I watch the guys pushing down-and-backs up and down the court. I’m staring at the hoop when I hear Al explain that most of the rules are the same as “able-bodied” basketball, which is what they call regular basketball. 

“How high is the basket?”

“Ten feet. Everything about the court is the same.”

“You have to dribble?”

“Yep. You can’t do more than two pushes without dribbling.”

I nod, wondering how they’re supposed to push and dribble at the same time, let alone things like crossovers or three-pointers. I think back to our final post-season game last year. That three pointer I barely missed against Melrose that would have put us within one basket with under a minute left. Half of us were in tears after losing that game, and I vowed I wouldn’t miss the shot next time. 

“I guess y’all don’t really do three-pointers in wheelchair basketball,” I say, realizing I’ll never get that second chance.

Coach raises an eyebrow, then calls out to one of the guys. “Hey O! Shoot a three.” Al tosses a ball to this tall dude with no legs. He’s wearing a durag and a glove on one hand. He pulls up and drains a shot from a few feet behind the three point line. Someone tosses the ball back to him and he does it again.

I close my mouth, which was just hanging open. I try to picture myself making a shot like that, but I can’t shake the image of me struggling to get the ball up to the basket in that hospital.

Coach checks his watch, then blows his whistle. “Alright, gentlemen, get some water!” 

Everyone’s breathing heavily as they get water and start shooting around. A couple guys come over and introduce themselves: a redhead man in his thirties who towers over us. A lanky light-skinned black guy with muscled arms who looks like he could play for the able-bodied Grizzlies team if not for his skinny legs. 

They ask me questions, and I tell them about my gunshot injury, how I was in the wrong spot at the wrong time, running with some guys I shouldn’t have been running with. I leave out the depression that came after I woke up and realized I wasn’t dead but that my life was over. I don’t mention all the tears I cried about things I’d never do. Play basketball. Drive a car. Have a girlfriend, maybe a family some day. Talking to them is different though. Their faces say they feel sad for me, but not sorry for me like everyone else has up to this point.

This isn’t what I thought it was, and I finally admit to myself how much I want to be a part of it. But my mind flashes back to rehab…

“You alright, Trey?” Mom asks. 

I nod slowly and mumble, “I don’t know if I can do all this.”

Al puts a hand on my shoulder, and his voice changes to that of a father giving advice. “Don’t cut yourself short. These guys were all in your same position at one point.”

“This takes time, you feel me?” says Archie, the lanky, light-skinned guy. “We gonna get you out here hoopin’ though.”

Al calls out to the guy who was draining threes. “Big O! Come here for a minute.”

“What’s up, fam?” O says, shaking my hand.

Al points to me and tells Big O how long I’ve been in a chair.

“Man, you’re real fresh,” O says. “This junt don’t get easy, but it gets easier, you feel me?”

I nod and listen to Big O tell about his accident, how he coped with everything and still is coping, how he was intimidated to get out on the court at first too. I watch him go back out on the court and post someone up on the block, and I wonder how he was ever scared. 

“What do you think? You gonna come back Wednesday?” Al asks as the players scrimmage. “We’ll get you in a ball chair, see how that feels.”

I look to my mom, who I can tell is holding back an I told you so smirk. “Maybe. I’ll think about it,” I say. I’m sure Mom is rolling her eyes because she can tell how much I want to be part of this.

Once practice is over, everyone convenes out in the parking lot. While most of the players debate about what defensive set they should run against some of the teams they’ll face in an upcoming tournament in Alabama, the guy who was hitting reverse layups before comes over to me.

“It was Trey, right?” he asks.

“Yeah. And your name was…”

“Justin,” he says, giving me a fist bump. “Four months ago, huh? That’s tough. You’re still relearning how to live life. I bet you have a lot of questions.”

I shrug. 

Another guy leans over to us. “He’s wondering the same thing we all wondered after we got injured, and the answer is yes, you can still have sex.” 

“Manners, A.G.!” Justin says, nodding toward my mom. 

I’m avoiding eye contact with her and dying of embarrassment inside, so I change the subject.

“Well, like, how do you drive a car?” I ask.

Justin takes me and Mom over to his car, and he shows me how the hand controls work, how he gets his chair inside. He shows me a picture of his wife and his two-year-old daughter sitting in his lap. He tells me about playing basketball in college, becoming a science teacher, about how disability is never an excuse for not doing something in life. 

Then he says something that makes me cringe.

“You know, I’ve seen a lot of disabled people never try things because they’re afraid of failure. Don’t make yourself more disabled than you actually are.”

My mom is beaming. “Now that’s some great advice! Sounds like something I’d say.” 

I glare at her, then roll my eyes. “Mom’s got a new catchphrase now. I’m going to be hearing that twice a day.”

Justin laughs. “Well, I think there’s a lot of truth to it. Anyway, I need to go. We going to see you Wednesday?”

I look to my Mom, who indicates it’s my decision, then back to Justin.

“Yeah. Yeah, I’ll be here.”

Author’s note:

I wrote an abbreviated version of this for a flash fiction contest a few years ago. A few years later, I rewrote and expanded the story for publication in the Memphis-themed anthology, Malfunction Junction.

I think Memphis is a lot like a kid going to a wheelchair basketball practice for the first time. Down on his luck, going through some really hard stuff. But also so full of potential, just needing permission to dream of what he could become. That his life isn’t over yet.

That’s what wheelchair sports do for people.

And special thanks to Quain and Al for keeping the team going here in Memphis all this time, despite all we’ve put you guys through 🙂
