In this experiment, students create a model of the water cycle and learn about its crucial role in moving water around the Earth.

How does a cloud form? This resource demonstrates how to create a cloud in a bottle. This makes a great experiment for a science fair project.

Create a fog chamber by rapidly expanding air in a jar in this activity. This activity uses a match in a jar to bunch water into tiny droplets.

Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.

Have you ever been to a tide pool during low tide? Some intertidal animals in the low tide zone are left in a tiny pool of water when the tides go out. Other intertidal animals that live in high tide zones may be left to dry out during...
