Day 144: Lab Practical, Board Meeting, & Lego Reaction Types

AP Physics 1: Lab Practical

Today was our last day of regular class before the AP exam. We worked on a lab practical where students figure out where to drop an unrolling toilet paper roll so that it will hit the ground as a roll that is simply dropped. I’ve got a worksheet where I added some questions to hit most of the topics from mechanics. I didn’t have any groups finish, but they did a lot of good thinking.

 

Physics: Plane Mirror Board Meeting

Students whiteboarded their results from Friday’s plane mirror lab. Several groups had some trouble distinguishing between units and variables in their equation because they were thrown off by the unitless slope, but we were able to work through it.

Chemistry Essentials: Lego Reaction Types

Students did a lab manipulating cubes to go from the reactants to the products for the major types of reactions we are learning to reinforce what is going on at the particle level. I usually use Legos, but forgot to ask a colleague to bring them in, so we pulled out the Mathlink cubes.
