In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

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

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

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

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 observe the effect of transpiration as water is moved from the ground to the atmosphere.

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

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

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

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.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

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

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity (on pages 29-35), learners examine water pollution and filtration.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.
