When Biology Gets Complicated, Make It Physical
Physical modeling transforms biology from static diagrams into tactile logic. By moving pieces through a sequence, like a signal cascade or enzyme reaction, students experience the "why" behind the "what."...

How to Teach Valence Electrons with Handwarmers
I’ve found that the best way to start a lesson on valence electrons isn’t with a textbook—it’s with cold hands and the phenomenon of handwarmers. In a class recently, we...
