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

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

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 three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this water activity, learners explore how water drops behave on different surfaces.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.
