Our class did an experiment with jetties, sand,water and erosion. Everyone in our class did three projects. In the first one we did a project about rain and the second one we built a jetty and the third one was the desert one. Erosion is caused by wind and water. My favorite project was the one with the jetty, because we could make waves with a ruler and we made a rock wall for our jetty. The whole class made an animation on one of the projects we did.

I made an animation and I drew a big hill with dirt. The water was coming up higher and higher and then when the water got really high, some of the dirt washed into the water. Then my animation just went back to the beginning again.
