In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

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, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

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 explore clouds and how they form.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners build small animated toys that move.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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).

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
