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 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 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.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

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

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