In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.
