8th grade science

In 8th grade science, I learned about roller coasters, wave lengths, and water pollution. We were learning wave lengths to see how sound worked and other things. we built roller coasters and they had to have a steep hill, a loop, and a turn. We had like two weeks to build it and decorate. I think we did pretty good. I was doing a water pollution google slide project I think I did really well on it. My favorite project that I did was a little solar panel project and we were going to cook s'mores on it but in was too cold out side so we just ate them normal inside and the Teacher just graded it on how it looked if we did everything right. After that, we watched meerkat manor.
