Day 73: Jelly Donuts and Bicycles

Wednesday, Jan 17

Physics: The other teacher gave me a video to show about the energy consumption of Tour du France riders that used jelly donuts to talk about what athletes did with all the calories they consumed, so I gave that a try. It was interesting to watch. Tomorrow we’ll be moving on to phase change, which is like my favorite topic ever.

Honors Physics: We developed a rubric for the upcoming paper/project summative assessment. The prompt is: “How do scientists use light behaviors to gather information about the universe?” Specifically, it is asking them to talk about how reflection, refraction, diffraction, and interference are utilized in data gathering. I’m totally fine if the default to telescopes and diffraction gratings. I also told them that they needed to show me that they understand how interference works, but they don’t have to spend a lot of time on it in the applications part, since interferometry is a lot harder to get a handle on than a telescope. However, if they want to write about gravity waves, do I have some resources for them!!!

Next content on the menu is doppler effect and learning about Hubble diagrams, dark matter, dark energy, and stuff moving away from/toward other stuff. Following that with a discussion of CMBR, and we’ll finish up our Cosmology Unit that is basically applications of waves and optics. I am 100% ok with this.

AP Physics: Working on APC 1999EM3 practice problem. It took them the entire 45 minute period. We had a discussion about eventually needing to speed that time up by 3, but I am absolutely fine with them spending this time to work through it perfectly and continue building basic understanding. Speed will come. That is not the goal right now.
