Dancing Popcorn

We did an experiment today to see popcorn dance. Before we could do the experiment we filled out our experiment sheet. We listed our materials, the procedure and then told our hypothesis or prediction for what was going to happen. We talked about our hypothesis before we started the project. The first thing we did is get our materials ready. We mixed water, vinegar and baking soda together in a jar. It created a special gas called carbon dioxide. Because we are learning about forms of energy in Science, we tried to explain how this energy was created. The carbon dioxide created bubbles. The bubbles stuck to the popcorn in the bottom and made them have kinetic energy. This energy and the force of the bubbles moved them to the top. When they got to the top, the bubbles popped and they fell to bottom. After a while there was less carbon dioxide. The bubbles started to get weaker and there was less force to pull them to the top.
