Water

Step 1. Questions

All living things need water. Not any water will do, however. Most living things need fresh water, which is water without much salt.

Fortunately, water is a renewable resource. This means that processes in nature keep supplying water over and over again. Together, these processes are called the water cycle. Most living things—including people—depend every day on the water cycle for their water needs.

For this e-Journal project, you will research and report on water. Here are some questions to guide your research.
  • What are the processes of the water cycle?
  • How does water come into people’s homes?
  • What are some different ways that people use water?
  • How does water get dirty, and how is it cleaned again?
  • What questions do you have about water and its uses?
Are you ready? Begin by visiting the first three Web sites listed in Step 2. Look for the answers to the questions listed above. Write down what you learn in the note-taking boxes.

You may use search engines to research other Web sites. Or read about water in books or encyclopedias. When you are ready, follow Steps 3 and 4 to write your report.



Step 2. Research

Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
