We were learning about matter. We made root beer floats to learn about changing matter. First, it started as a solid when we put ice cream in a cup. Then we put in root beer. Root beer is a liquid. It had a gas in it because it had bubbles of air. The ice cream started to melt because the root beer was a little warm. We observed the change. It dissolved in the liquid. Then we ate it! It was super yummy!
