AP Physics: Final Projects
We went to a computer lab today for students to continue working on their final projects. The majority of students are making good progress; they had a milestone due today, and I’m looking forward to reading their progress. One student is analyzing a scene from one one of the Fast and the Furious movies to determine whether the physics is plausible. He spent some time today getting measurements from Google Maps to help with his analysis.
I gave feedback on project proposals electronically, and ran into an issue where one student hadn’t read the feedback to see their project needed some significant changes. I wish I’d taken time to have individual conferences with students about their proposals to make sure students were aware of my feedback.
Physics: Lens Ray Diagrams
Students worked on some qualitative ray diagrams for lenses today. Students are continuing to do very well with ray diagrams, though I wish we’d spent a little more time on planar refraction. A lot of students had trouble with the idea that a lens bends the light the same amount, regardless of characteristics like the location of the screen.
Chemistry Essentials: Reaction Rates
We spent some time discussing yesterday’s lab, using particle diagrams to think about why certain factors sped up reactions. A few ideas from earlier in the year, like the fact that particles move faster when they are at a higher temp, came up, which was great. Afterward, students did a reading and answered some questions to try and focus on the role of energy in affecting reaction rates.
