In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners use simple materials to create giant bubbles.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

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

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

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

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

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 conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners stain fabrics--on purpose!

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
