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

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

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 indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

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 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.

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.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

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 water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

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 quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

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

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
