In this activity, learners build water-propelled engines from soft drink cans.

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.

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

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

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
