Human beings are about 67% water. In fact, every living organism, whether composed of one cell or many millions of cells, contains water. Water is needed to transport nutrients and oxygen throughout living organisms and to carry out waste. Water also is vital for cooking, cleaning, growing crops, raising animals, transportation, production of electricity and manufacturing. Without water we would not only be unhealthy, we would not be alive.

Have students work individually to complete the pre-assessment.
Procedure and Extensions
Ask students, Why is water important? Have students devise and write down reasons why water is important in their science lab journals/notebooks. Tell students they may add to their lists as they complete the unit.
Explain to students that they will complete a pre-assessment to see what they already know about water.
Have students complete the pre-assessments individually; then collect and save the sheets. You should have students refer back to their pre-assessment answers at the conclusion of this unit to make any corrections based on the knowledge gained in the unit. This can be used as one component of the post-assessment activity (see Extension, below).
Refer to the post-assessment instructions and have students prepare drawings and write about (depending on grade level) four of the most important aspects of water for health. Then, revisit the drawings at the end of the unit and have students expand their previous drawings or make new drawings to express what they have learned.
Handouts and Media
Students examine uses and properties of water, investigate water pollution, get tips for saving water and keeping the water supply clean, and learn about water in the human body.
Mr. Slaptail and the cousins, Rosie and Riff, investigate harmful changes occurring in the local creek, pond and marsh.
Students take a fresh look at water and examine its critical importance to the well-being of all living creatures. (11 activities)
