This week we talked about the 3 states of matter and did a few fun experiments. My girls already knew a little about solid, liquids, and gases. They knew that heat could change water into different states of matter. So instead of focusing on those things, I taught them about the molecules and more about gases.
I found this great video explaining matter and molecules. They also liked singing along with this song. After watching the video I had them pretend they were molecules. I called out either solid, liquid, or gas and they acted like those molecules. For a solid they stayed close to each other and stayed still, for a liquid they moved a little further apart and walked around, then for gas (their favorite) they ran around and spread out.
One of the experiments we did they loved! Pour vinegar into an empty water bottle about a third of the way. Then get a balloon and fill it about half way with baking soda. Without letting the baking soda fall into the bottle, attach the balloon onto the top of the water bottle. Then have them pour the baking soda from the balloon into the bottle and watch what happens.
Writing down their hypothesises before the experiment.
The vinegar is in the bottle and the baking soda is in the balloon.
I love her face here.
Science behind it:
When baking soda and vinegar mix they form the gas carbon dioxide. Gasses need room to spread out so the gas filled the bottle and moved into the balloon to “blow” it up.
