In this activity, learners explore center of gravity, or balance point, of stacked blocks.

\$1 - \$5 per group Ages 8 - 14 10 to 30 minutes
Source Institutions
In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

\$1 - \$5 per student Ages 6 - 14 1 to 2 hours
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

1 cent - \$1 per student Ages 6 - 11 10 to 30 minutes
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

\$1 - \$5 per student Ages 8 - 14 30 to 45 minutes

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.

1 cent - \$1 per student Ages 8 - 14 10 to 30 minutes
Source Institutions
In this project, students explore how levers work, by making a puppet with moving limbs.

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

\$10 - \$20 per group Ages 11 - 18 1 to 2 hours

\$1 - \$5 per student Ages 6 - 14 30 to 45 minutes
Source Institutions
In this activity, learners explore accuracy and precision.

Over \$20 per group Ages 8 - 18 2 to 4 hours
Source Institutions
In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

\$5 - \$10 per student Ages 8 - 18 1 to 2 hours
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.

\$1 - \$5 per student Ages 6 - 14 1 to 2 hours
Source Institutions
In this physics activity (page 3 of the PDF), learners will move a load using a lever of each of the 3 classes. They will explore the differences between these classes and which are more effective.

\$1 - \$5 per group Ages 14 - 18 10 to 30 minutes
Source Institutions
In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

\$5 - \$10 per student Ages 6 - 14 30 to 45 minutes
Source Institutions
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).

Over \$20 per group Ages 4 - 11 10 to 30 minutes
Source Institutions
In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

1 cent - \$1 per student Ages 14 - 18 10 to 30 minutes
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
