What is your project about? How different the pH of different liquids affect erosion. Why did you choose this project? I chose this project because it interested me, and I also wanted to see what would happen to the block that I used. What was your result/overall conclusion? My result overall was that the lower the pH more of the material came off. Why is your project important? It will help us against acid rain and other natural forces like it.

  1. Great experiment! Your use of photos and graphs made this project easy to follow. You did an excellent job analyzing your data and discussing possible reasons for the varied results. I appreciate that you picked something practical.

  2. It is obvious that you enjoyed this project, that you stuck with it for two weeks and that you learned while doing it! Yay! Continue to be curious, notice & wonder and ask lots of questions! You are a scientist and engineer!
