Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners will test soil content using their sample, some water and a container that seals.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).
