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

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

Learners investigate how drag affects the falling rate of objects.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.
