Day 12: Linearization & Heating

AP Physics: Linearization

Most students finished their position vs. time graphs, so we took some time to talk about linearization. I really like the ways that uncertainty played into the discussion. In particular, students were quick to recognize that the line of best fit doesn’t go through the error bars and that the intercept is much further from 0 than the uncertainty. This motivated nicely that, even though the line had a good r2 value, it wasn’t good enough.


Earth Science: Heating

Students placed thermometers at different angles in front of a lamp to simulate the sun striking the surface of the earth at different angles. I like that this lab starts with a question, namely ¬†“Why is it hotter at the equator?” Next time, I’d like to involve students in more conversation about how we can model that in the lab since I think many lost the connection between the question and the data they were collecting.
