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 engineering activity, challenge learners to invent a water filter that cleans dirty water.

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

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

In this activity, learners make their own "tornado" using two soda bottles and water.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

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 discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

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

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

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