In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

Learners explore water's property of cohesion through two investigations.

Learners demonstrate how water can distort, refract and magnify light.
