Day 72: Projectiles, Forces Practical, & Qualitative Gas Laws

AP Physics: Projectiles

We worked through some problems I got from Michael Lerner where students apply other models from this year so far to an object dropped straight down and I was pleased with the connections students were making. I also asked students to predict what should happen to the time if the object were heavier and if it were launched horizontally, and got some great discussion. We wrapped up by trying each and checking the results with slow-motion video.

 

Physics: Forces Practical

Students wrapped up the forces practical from yesterday. I scaffolded the practical more than usual by breaking it into small steps, asking students for each representation and several calculations along the way. Several students commented that was very helpful when they took another look at the problems from earlier this week.

Chemistry Essentials: Qualitative Gas Laws

I got out the syringes for students to make some qualitative observations about the ideal gas laws. The ice water baths didn’t produce much change for the groups I was able to talk to today. With this class, I’m spending more time redirecting students or dealing with groups damaging lab equipment than I am talking to students about chemistry, so I need to think about how to shift that. There is a para who is going to work on helping to keep students on task. I also need to remember the instructional coaches have offered to help manage things on lab days.

Classroom Display

Earlier this week, I put up a “Scientists can be…” display inspired by Liz Mastalio. Its been a lot of fun listening to students react to it; some are looking for which ones they don’t know while others are clearly drawn to specific identities. My AP students have been telling me who they’d like to see up there, so I want to open the door for them to submit a poster with a label. That could help me get some identities I missed that matter to my students.
