Waves (and Prom week ;)

I. Research Question

The polar system is very complicated and difficult for many to understand. However, there are various reasons why it is important to grasp. First, one could become a scientist or become involved in a field that helps humanity prepare for catastrophes. One could predict and work around natural disasters. Also, humanity can develop and advance together.

II. Summary

This week was not so stressful due to no AP exams for myself. Since many students were taking AP U.S. History, the seniors and any other students present had the opportunity to complete worksheets from the last lab. They were in relation to magnetism and electricity and they were super hard. Afterwards, we had an extremely long class in which we worked on the PhET Waves Station Lab. They were quite challenging as well. We did an intro to understanding waves, how they function, what they are, how they are measured, and their relation to color and sound.

III. Question

How many types of waves exist?
