In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners discover that some things only stand up while they are spinning.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this physics activity (page 10 of the PDF), learners will make a can that will roll back after it has been rolled away to observe the interactions of kinetic and potential energy.

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

Did you know that you would be a different age if you lived on Mars? It's true!

This lab activity has learners create a pendulum with a one-second period.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

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

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.
