In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners create painting machines that can paint moving forwards and backwards.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
