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

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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

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

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

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

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this physics activity, learners will explore buoyancy.

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

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners will explore density and it's relationship with mass.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.
