Home Who We Are Sharing the Planet How the World Works How We Express Ourselves How We Organize Ourselves Where We Are: Place & Time Citric Acid Experiment In this experiment, my group and I were trying to find the concentration level of citric acid. This experiment was one of the best experiments my group and I had done this year so far. It was very fun. I learned that that after the water evaperates citric acid crystals are left the shape of a hexagon. This experiment was very interesting. Physics Experiment This is my graph, I did an experiment on how high ping pong balls bounce. I dropped the ping pong ball from diferent hights. The first time I drpped it at 10cm, and it bounced 8cm. The second time I dropped it from 15cm, and it bounced 13cm, and so on. This project was very fun and interesting, I liked it a lot.
