Today we worked on Mystery Powders. What did we do? We put some baking soda in a sandwhich bag.Then we added vinegar to it. Then it started bubbling like Sprite. It turned into a gas then into a liquid.This is called a chemical change not a physical change a chemical change is when two things mix and won't change back and something new is created. In a physical change, they can change back to the way they were, like water turning into ice and then melting back into water. It was awesome . It was one of the BEST science projects Ever.
