Welcome to Siebert Science!

I make science YouTube videos to “flip” my Anatomy & Physiology,
Physics, and AP Chemistry classes. I hope you find them helpful!

These first-year chemistry videos align with the excellent program Positive Chemistry. I’ve used Positive Physics with my classes, and another teacher here in Memphis is expanding the program to chemistry. Positive Chemistry is in the beta stage now, but you can try out what we have so far here! (Positive Chemistry is free while in the beta stage!)

  4. Moles to Liters (at STP)
  5. Multi-Step Mole Conversions

Medical Case Studies Elective

Back in the day, I taught a semester elective class called “Medical Physiology.” The class utilized case studies from the NCCSTS. You can find more about that class here.
