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

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

You just ate a big meal and feel heartburn coming on. You take an antacid and feel better. Why? Heartburn is caused by stomach juice (an acid) burning the esophagus.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

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 create models of ionic compounds and observe the chemical formula of binary molecules they have created.

This activity was designed for blind learners, but all types of learners can play this game to learn about the major polyatomic ions (an ion that consists of two different elements).

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

In this activity, learners electrically plate zinc onto brass objects.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.
