A volcano!
We worked in buddies to make a volcano out of lego. We added one teaspoon of baking soda into the canister and then poured 1/4 cup of vinegar in. Wow, what a chemical reaction. Bubbles slowly rising up and over the top to pour over the sides. That was the carbon dioxide that was formed when they mixed together. Not only did we do the experiment but we took photos on a app called Stop Motion. Next week we will be turning our experiment into a movie for others to watch.
