Module 2:

The Water Cycle

Lesson Topic:

The Water Cycle

Grade level:

9th ? 12th Subject:

Earth Science / Physical Science Length of lesson:

5 class periods Content Standard(s): (Located in Section 1, Resources for All Modules)

Understandings/Goals:

Students will understand: The water cycle and its importance for Earth

Enduring Understandings:

? Water is essential to all life on Earth; however, there is a limited supply of fresh water available. ? The water cycle is a recurring natural pattern with distinct processes which circulate water around Earth. ? Water has unique properties in its three states of matter which are important to the processes of the cycle. ? Some events in nature have a repeating pattern. The weather changes some from day to day, but things such as temperature and rain (or snow) tend to be high, low, or medium in the same months every year. ? Water in its three states moves from one place on earth to another in a continuous cycle called the water cycle. The water cycle includes the processes of evaporation, condensation, precipitation and the movement of water over and into the ground.

? Water can be a liquid or a solid and can go back and forth from one form to the other. If water is turned into ice and then the ice is allowed to melt, the amount of water is the same as it was before freezing. ? Water left in an open container disappears, but water in a closed container does not disappear. ? Weather is a daily occurrence, climate occurs over an extended period of time. ? Different temperatures affect water, by changing the states. ? Some common substances, such as water, can be changed from one state to another by heating and cooling.

? One common weather phenomenon is precipitation, which can be in the form of rain, sleet, snow or hail.

? Clouds are made of condensed water vapor in the form of drops of liquid or crystals of ice. Rain falls from clouds when the drops of water become too heavy to stay suspended in the sky and are pulled toward the earth by gravity.

Essential Questions:

? What cycles do we observe in the natural world? ? What happens daily to the water on earth? ? What is the water cycle?

What makes the water move through the cycle? (sun,

gravity, physical properties of water)

? Why is the water cycle important?

How is the water cycle important to plants

and animals? (It moves water to them; it makes water available at different times) ? How do we distinguish between weather and climate? ? How does the water cycle impact the environment? ? What would happen if the sun's energy were blocked from the Earth? ? What might happen if all of the Earth's water stayed in the oceans? In the clouds?

Student Objectives (Outcomes)

Students will be able to:

? Be able to determine uses of water and identify sources of water.

? Be able to explore how water changes states (i.e., solid, liquid and gas) from one

form to another.

? Determine the relationship between temperature and the different states of

water.

? Be able to describe the role of water in some weather phenomena.

? Be able to explore the relationship of the water cycle to weather.

? Identify the various types of precipitation.

Performance Tasks:

Service Learning Performance Tasks

1. Water Cycle Educational Presentation

? Design an exhibit that can be used when you travel to schools with the purpose of teaching younger children about the Water Cycle. Make sure your presentation: a. Provides visual demonstration of the Water Cycle ? such as a poster or a model.

b. Explains the water cycle in detail and include the process of each stage

c. Shows the importance of the Water Cycle's recycling of water of Earth's fresh water supply (changing salt water of oceans into fresh rainwater).

Use: Educational Presentation Rubric in the Student Graphic Organizer

2. A Water Cycle Production ? You are a writer and producer for the theater that hosts educational productions for elementary students. You have been asked to write a script that will help tell the story of Drip the Raindrop and his adventures through the water cycle. You should identify the characters to represent the important elements in nature that play a role in the water cycle. These characters will all be part of your story that should be entertaining but also educational. Your play should

a. Creatively explain all processes of the Water Cycle and

b. Persuade the children in the audience to help value and preserve our limited fresh water resource.

Differentiated Service Learning Performance Tasks

1. Create a flyer to promote the Water Cycle Educational Presentation or Water Cycle Play. Put a picture of the water cycle and two facts about it on the flyer so that people will be curious to learn more.

(Use: flyer Rubric in the Student Graphic Organizer)

2. Create a poster with pictures showing what the water cycle looks like. These images may be from a book, the Internet, photographs that you or your family have taken, or pictures that you draw.

(Use: flyer Rubric in the Student Graphic Organizer)

3. Create captions for the items you have put on your poster. You should write at least one sentence telling about each item you have on your poster.

(Use: flyer Rubric in the Student Graphic Organizer)

Background

Please note that the supporting Background information for all modules is located in Section 1: Resources for All Modules.

Overview

? The water cycle is Earth's natural mechanism for circulating water on, above, and below the surface of the planet. Although the balance of water on Earth remains fairly consistent over time, climate change is affecting parts of the water cycle and the distribution of our water resources. Understanding the hydrologic cycle is basic to understanding all water and is a key to the proper management of water resources.

? In this module, students will examine all the stages in the water cycle to gain a deeper understanding of how this process works and the implications it has on our planet and in our lives.

? Students will relate their knowledge of the properties of physical matter to identify how water is changed and moved by this cycle in nature.

? Students will also apply their prior knowledge of cycles to describe how the processes are related and the impact that people and the environment have on the cycle.

? Students will begin to understand the limited supply of fresh water on our planet and think about ways to maintain and preserve this water for human use.
