Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.
