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.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

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.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

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

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

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