In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners learn about friction by making their own miniature hovercraft.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.

In this activity (page 2 of PDF under GPS: Kinetic Sculpture Challenge Activity), learners will predict which objects have to overcome the most static friction to slide down a ramp.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.
