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

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.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

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 (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

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

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

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/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 nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

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 will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.
