Physics: Final Review

Students continued working through the lab practicals to review for the final exam. Overall, I’m pretty happy with how the review has been doing, though a lot of groups were confused about what they were being asked to do on the standing waves practical. I need to revise the directions to make it clearer that they should calculate the length of the tube needed to resonate, then use the materials to test it.

Find the length of the tube to make a tuning fork resonate

Find the index of refraction for vegetable oil

Find the mass of the washers

Use at least 3 mirrors to hit a target with a laser pointer

Chemistry: Isotopes

Students used what they know about isotopes to determine how many pennies in a sealed container were made before 1982 vs. after. They struggled to make the connection between the lab and what we’ve done so far on isotopes, so I need to make some changes to help students better build that link.
