Third grade scientists continued investigating thermal energy and matter in lab. This was such a fast paced lab, I wasn’t able to capture many pictures. The following demonstration was an impressive way to explore heat energy and air pressure concepts.  Click here to watch a video.

From our previous experiments, we learned that warm air or liquid rises and cool air or liquid falls. I placed hot water (red) on top of cold water (blue) and the colors remained separate. Then I reversed the procedure and the colors immediately mixed. Click here to learn more.
