Volcanic Eruptions

We created our own volcanic eruption in a bottle this afternoon. We used hydrogen peroxide, dish soap, and a little bit of food coloring to make it even cooler. We then added yeast that had been dissolved in warm water to the mixture and that's when the magic happened! The mixture of chemicals created a chemical reaction and the mixture foamed and exploded.

After we had finished our own personal volcanoes, Mrs. Owen showed us a bigger eruption using high powered chemicals we were not allowed to touch. (The high grade of peroxide she had could burn our skin, so we had to watch!) The eruption was even bigger than the ones we had created in our bottles! A lot of heat was produced in both experiments. Why is this? When a chemical reaction occurs, it creates energy. As more energy is produced, heat is created. Check out the photo album below to see pictures from our volcanic adventure!
