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

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

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

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.

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.
