To be honest, I like the spring term the best, not only the weather is getting warmer, but also the lab experiments are having so much fun!
This term the teaching lab is related to waves and optics. (Sometimes we need to work in the dark but we still have good time in the lab.)
Most of the students have good feedback, but some of them get confused about which angle should be used for calculation. Therefore, they need to spend more time to observe before they do the analysis.
At the end, almost everyone has the correct concept of this lab.
