In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
