Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In the kitchen, learners can perform their own density investigation.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this physics activity, learners will explore buoyancy.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.
