Day 141: Ray Diagrams & Lego Reaction Types

Today was the second day in a row I was gone for a field trip.

Physics: Ray Diagrams

Students practiced drawing and interpreting ray diagrams using a worksheet from the Modeling Instruction physics curriculum. Based on what I saw of their work from yesterday, I’ll need to do some work with them tomorrow on details like including arrow heads.

Chemistry: Lego Reaction Types

Students used Legos to represent different ions and worked through examples of each reaction type. I’m hoping that manipulating the Legos helped make what’s going on in some of those reactions more concrete. I’ll find out for sure tomorrow.
