AP Physics 1: Projectiles
Students worked through some questions I got from Michael Lerner to introduce projectiles by having students represent the motion of a falling object using key tools from each of the models we’ve covered so far this year. This day always makes me really happy I wait until the end of linear mechanics to do projectiles.
Students worked on finishing up their data collection and graphing from yesterday’s kinetic energy lab. I was really excited about how many students recognized on their own that they would need to linearize this data; even groups that had data that looked fairly linear, which is common with this lab, realized their intercept would make more sense with a parabola than a straight line, which was awesome. January and February are always a tough time of year, and a clear reminder of how much my students have grown so far this year was just what I needed.
Chemistry Essentials: Gas Law Problems
Students worked on solving problems using the gas laws. First trimester, I switched from using the formulas to having students use proportions to solve the problems, which helped make the math more accessible. This trimester, I added a question where students had to determine whether the unknown quantity should increase or decrease based on their particle diagrams, which made a big difference for students when deciding whether to multiply or divide to get their answer.
