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 investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

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

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

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

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.

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.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
