In this activity, learners build a carousel toy that spins when pushed down.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this physics activity, learners conduct two experiments to explore free-falling.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Learners build simple catapults and use them to launch cotton balls.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

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.

Learners construct and launch paper helicopters.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

Get all wrapped up in a lesson about skin!

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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