What happens when you mix a solid (baking soda) and a liquid (vinegar)? Well, that’s the experiment the first graders conducted on Wednesday. As a follow up to their huakai to the Hawai`i Volcanoes National Park, students simulated a volcanic eruption, slightly modified. This is also a preview of their next unit of study, states of matter.
Instead of having the “lava” flow out of the water bottle, we covered the top with a balloon in order to see what would happen when it mixed. Students found out that the mixing of the two matters crated a gas, which was obvious by the blowing up of the balloon.
