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 activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
