In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
