This interactive, animated graphic helps explain the water cycle to younger students. The animation, with sound, explains the various parts of the water cycle and show how water moves from one part to another. Full description.

This interactive diagram of the water cycle invites students to click on a part of the cycle to get information about streamflow, surface runoff, freshwater storage, ground-water discharge, ground-water storage, infiltration, precipitation, snowmelt, runoff to streams, springs, condensation, evaporation, transpiration, water in the atmosphere, ice and snow, and oceans. A summary of the water cycle ... Full description.

This demonstration introduces the concept of water phases and cycling to younger students through observation, drawing, and writing. They will be able to explain how the Earth's water supply is recycled, form a hypothesis as to how/why the water cycle works, and use writing and drawing to explain how the cycle works. Full description.

This interactive tour of the water cycle allows students to follow a water molecule from a home's plumbing system as it follows different routes through the hydrologic cycle. Students learn about how water is used, treated, and returned to the natural environment where it can cycle through liquid, solid, and gas phases. Full description.

In this activity, students build a model illustrating the water cycle, and observe the results. The site includes a materials list, instructions, and information about the water cycle. A downloadable version is available, and the activity is also available in Spanish. Full description.

This site provides information about precipitation, evaporation, condensation, surface runoff, infiltration and transpiration, which are all part of the water cycle, a complex process that not only gives us water to drink and fish to eat, but also weather patterns that help grow our crops. The site has four sections. The introduction presents the overall concept while the second section covers each ... Full description.

This site contains basic information about the water cycle (hydrologic cycle) and the part that groundwater plays in it. The information includes all parts of the water cycle, including evaporation, condensation and cloud formation, precipitation, runoff, and infiltration. The aquifer with its discharge and recharge is also explained. This discussion is supported by a large diagram of the water cycle. ... Full description.

In this activity, younger students will construct a model which will allow them to identify the components of the water cycle and observe processes involved in the movement of water through the various components of the cycle. This activity can be done at home with common household materials and could be used by students who are home schooled. They will be able to infer evaporation and observe condensation, ... Full description.

In this lesson, students recognize the different forms that water takes and learn about where it exists in the environment. Using class discussion, multimedia resources, and experiments, students model the water cycle and explore how it can be used to create fresh water. They will identify the ways that water moves through the environment, recognize that most of Earth's surface is covered by water ... Full description.

Through five main processes (condensation, precipitation, infiltration, runoff, and evapotranspiration), water is perpetually cycled through the Earth system. This interactive, animated feature introduces students to the hydrologic cycle and provides a brief explanation of each of the five processes. A background essay and list of discussion questions are also provided. Full description.
