Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

In this chemistry demonstration, acid rain is simulated in a petri dish.

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.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
