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

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

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

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

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