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 introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners explore the great pump in their chests--the human heart!

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
