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.

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 group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

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 activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

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.
