particulate level

Why Do You Make Us Draw so Many Particle Diagrams?

Living at the macroscopic level, it’s no surprise that understanding and effectively communicating chemistry concepts can often be a challenging endeavor. Attempting to rationalize our observations through particle-level interpretations requires us to think in less intuitive ways that often create a cognitive barrier for our students. And for good reason.

Stop Motion Animation Galvanic Cell Process

With few materials available to complete wet labs in my school, I have to be creative with covering lab concepts in my AP chemistry course. I was looking for a way to make sure my students were getting the idea of the macroscopic changes that take place in a galvanic cell without necessarily being able to do the wet lab. The particulate model that is part of the Energizer Lab inspired me to write an end of unit assignment for my students using Stop Motion video apps.
