Water Unit

Section: 1

 

 

 

 

  Introduction

Water is a crucial ingredient for life on Earth: It nourishes people, plants, and animals and plays a major role in the planet's weather and climate. The water cycle is Earth's natural mechanism for transporting, cleansing, and recycling water between the surface and the atmosphere. In this lesson, students recognize the different forms that water takes and learn about where it exists in the environment. Through class discussion and experiments, students model the water cycle and explore how it can be used to create fresh water.

 

 

 

 

  The Task

  • Understand that water exists in the environment in different forms
  • Identify the ways that water moves through the environment
  • Recognize that most of Earth's surface is covered by water but that only a small amount is fresh water

1. Watch the Water Phases Flash Image . Answer the following questions on the Wiki.

  1. Did we see all the different phases in the slideshow?
  2. Can you think of any more examples to add to our list?

2.Watch the Global Water Distribution Flash Interactive. Explain the main difference between water in lakes and rivers (fresh water) and water in the ocean (salt water) on the Wiki.

3. Discuss what precipitation is and the different kinds of precipitation. Watch the Observe Precipitation QuickTime Video. Answer on the wiki:

  1. Where does precipitation come from?
  2. Why do you think there are different forms of precipitation?
  3. What happens to rain/hail/snow when it reaches Earth's surface?

4. Discuss how water is continuously cycled between Earth's surface and the atmosphere. Watch the Water Cycle Animation QuickTime Video once in its entirety. Play the animation again, pausing at each transition and have students explain what is happening to the water in each stage.  List the steps of the water cycle in more detail by going through The Hydrologic Cycle Flash Interactive

5. Watch the first segment of the Biome in a Baggie QuickTime Video.

IF you have responded to all of the questions via the wiki – you may listen to the following video.
