In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

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

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

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.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
