This is a simple and fun activity for learners to explore water and colors.

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

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

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

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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

In this activity, learners will explore how density is affected by temperature and how that can create currents.
