In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners make their own heat waves in an aquarium.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
