Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

This activity has learners observe water and compare it to other liquids.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

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 about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.

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

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.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

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.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

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

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.
