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

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

Learners build a lever and use it to lift a load. With the load on one end of the ruler, learners add coins to the effort cup at the other end until the load is lifted.

Learners construct a rocket from a balloon propelled along a guide string.

1 cent - \$1 per group Ages 11 - 18 30 to 45 minutes
Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

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

\$1 - \$5 per group Ages 11 - 18 45 to 60 minutes
Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Learners construct and launch paper helicopters.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

\$1 - \$5 per group Ages 11 - 14 45 to 60 minutes
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

\$1 - \$5 per group Ages 11 - 18 30 to 45 minutes
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

\$1 - \$5 per group Ages 11 - 18 30 to 45 minutes
Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

\$1 - \$5 per group Ages 11 - 18 30 to 45 minutes
Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

Using simple, inexpensive items, learners build and test submarine models.

\$10 - \$20 per group Ages 11 - 18 45 to 60 minutes
Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

\$1 - \$5 per student Ages 11 - 18 30 to 45 minutes
Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.
