In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

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

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

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

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Walk a toy to the edge of its doom, maybe it'll fall off the edge of a table, but it will safely stop right before falling.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.
