| Purpose The purpose is to experiment with different forms of citric acid with the same type of baking soda.
Hypothesis My hypothesis for the raw citric acid and baking soda is that it will swirl around in the container.
My hypothesis for the apple juice and baking soda is that it will foam over the container.
My hypothesis for the apple slices is that it will do nothing.
Materials • Three containers • Three plates • Apple slices • Raw citric acid • Apple Juice • Water • One cup • Three spoons • Baking Soda • Log book
Procedures 1. Lay out 3 plates on a table. 2. Put 1 container on each plate. 3. Put apple slices in one container, apple juice in the next, and the raw citric acid in the last container. 4. Add 1 spoon of baking soda to each container. 5. Stir the container with the apple juice with one of the spoons not yet used. 6. Add a cup of water to the container with the raw citric acid, then add a cup of water to the container with the fruit. 7. Get the last spoon and stir it the container with the fruit.
Observations First off, I did the container with the raw citric acid and baking soda. It fizzed over the container. Next, I did the apple juice and baking soda in the container. It just made a fizzing sound. Then finally, I did the container with the apple slices and baking soda. It did nothing.
Conclusion My hypothesis was wrong and right. The apple slices didn't do anything. So this was correct. The apple juice didn't foam over the container. This hypothesis was wrong. Instead it just made a fizzing sound. My hypothesis for the raw citric acid was wrong too. It fizzed over the container instead of swirling in the container.
Hm almost done now! : D | |
