Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
