Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

Learners construct and launch paper helicopters.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

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.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

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

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 observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

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

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
