We are learning about Matter during Inquiry. We have done 2 cool experiments this week.
Mixing Solid and Liquid
Students experimented with adding drops of liquid (vinegar) to solids (flour, sugar, salt, baking soda). They used a pipette (dropper) to drop a little liquid at a time. We took time to observe and record what happened. The most exciting step was watching the gas bubbles created when the vinegar was added to the baking soda.
Our next experiment was to see if we could harness the gas created by mixing vinegar and baking soda and use it to inflate a balloon. It worked! We tied off the balloon and noticed that the gas was very dense because the balloon dropped quickly to the floor. Both of these experiments can be completed at home with a few ingredients from your kitchen if you third-grade scientist wants to demonstrate.
