In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners explore a bucket of sand and beach objects.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.
