In this activity, learners build their own construction cranes using tongue depressors and pushpins.

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 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 guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

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

This is an online Flash game where learners can experiment with ballistics and how to compensate for the varying levels of gravity found on the planets of our Solar System.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this activity, learners explore the concept of force and how pulleys are used in everyday life to make work easier.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
