In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

No glue is needed for learners of any age to become marshmallow architects or engineers.

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

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.
