1 H 2 O and YOU School/program name Date

2 Background Information (for facilitator) Fresh water is vital to all life on Earth. Humans, plants, and animals need it to grow and thrive. The amount of fresh water on the Earth does not change; it is constantly moving through the water cycle. That means the fresh water that is here now is essentially the same fresh water that was here millions of years ago, and it is the same water we will have in the future, which is a strong argument for preventing pollution and encouraging conservation. In the U.S., we are lucky to enjoy easy access to clean water. In other parts of the world, it is not so easy. In fact, at least 1.2 billion people worldwide do not have access to clean water. The average American uses eighty gallons of water a day. However, household water use accounts for just 8 percent of total water usage. Most fresh water used in the United States is used for industry and farming. While fresh water seems like an abundant resource, it actually represents only about 3 percent of the world’s total water supply. Of that 3 percent, much of the fresh water exists as ice in glaciers. People use water in its various phases (solid, liquid, and gas) for many different purposes. Uses of liquid fresh water are almost endless, and include recreation, transportation, and food preparation, in addition to basic survival. Uses of ice (solid water) include cooling of food and drink (and, in the past, buildings); preservation of perishable materials; treatment of injuries; and recreation (e.g., skiing and skating). In extremely cold climates, ice can be used as insulation and even as building material. Water vapor is used in cooking (e.g., steaming vegetables); cleaning; sterilization of laboratory and medical equipment; household heating (radiators); and, perhaps most importantly, the generation of electricity.

4 Learning Objectives To explain the importance of water for living things To determine the water composition of our bodies To explore the concepts of access to and transport of water

5 Today’s Vocabulary Water Density Fresh Water Salt Water

6 Setting the Stage

7 How long can you go without drinking water? Video: Why Water Rocks

8 Activity: You Are What You Drink

9 How much water do you drink each day? Video: All Living Things Need Water

10 Activity: How Sweet It Is

11 Cyber Investigations

12 Project Time: Water Content in Fruit

13 STEMtastic Careers Why is the water industry considered a stable field for jobs? What are the benefits of working in a water-related job? What are some of the water-related jobs discussed in this video? What are some of the skills you need to work in a water-related job?

14 Engineering Challenge: Who’s Thirsty?

15 Mind Snacks

16 Engineering Challenge Continued

17 Notebook Reflection What have you learned about how important water is to you? What is your favorite water activity? How does it relate to water and you? Which careers you examined today most intrigue you, and why are you interested in them?

18 Wrap Up

19 Think about this… Because water is a renewable resource, that means there is an unlimited supply of it, right? Is it true that water always has a freezing point of 0°C and a boiling point of 100°C?
