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 activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.

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

If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

This is an online activity about acceleration. Learners will choose a speed and an angle in order to help a water-skier named Fonzie use a ramp to clear a shark.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

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

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity, learners create music from a series of bottles filed with water. Learners discover that the sound produced by each bottle depends on the amount of water in the bottle.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
