Lesson 1 - Where does water comes from and where does it go?

Lesson Plan

State Standards:

Physical Science, Grade 3-5

10. Describe how water on earth cycles in different forms and in different locations, including underground and in the atmosphere.
11. Give examples of how the cycling of water, both in and out of the atmosphere, has an effect on climate.

Essential Question:

Lesson Question:

Introduction:

As we look around us at the world, there is water, but the amount of water changes. Where does the water come from and where does it go?

Task:

Formulate a hypothesis and test it by conducting the following activity to answer the question: Where does the water come from?

Lesson Experiences:

Elicit: "Where did the water come from?"

Read each of the situations presented in the document below and determine (guess/infer) where did the water come from. Discuss your ideas with your partner/neighbor.

Where Did the Water Come From?

Engage:

  1. Form groups of 4 to 5 classmates and create the setup presented in the probe. Before starting the activity you must state a hypothesis to answer the question.
  2. Put some food coloring in the water and then make the ice cubes with the colored water.
  3. Place the colored ice cubes in a plastic container.
  4. Allow the cubes to sit on a table for an half an hour. Observe what happens.
  5. Discuss results and how the possibilities from the probe can be eliminated with the exception of one.
  6. Establish if your hypothesis was supported.

Explore:

Classroom materials

  • 2 beakers per group
  • graduated cylinders
  • science journals
  • markers
  • 1 lamp per group

Explain: Concept Knowledge Building Activity

Use your results to engage in discussion on what happened and what is evaporation.

Discuss where water is stored on our planet and how the sun's heat is constantly causing it to evaporate.

Create a web.

Watch the YouTube video on the water cycle.



Water Cycle Video



This process is called a cycle. A cycle is a process in which any material moves around in a system. The water cycle is the process by which water travels to and from the nine places where it exists on Earth.

In the experiment the energy source was the lamp; in our planet is the sun. This source causes the water to change from one stage to another.

Refer to the elicit and the engage activity to identify what happens to the water.

Discuss these concepts:


Elaborate:

You will create a diagram that shows the steps of the water cycle and explain in one paragraph what is occurring in the diagram.

Assessment (Evaluate Knowledge Expression):

Your comprehension of the water cycle will be demonstrated by your creation of a Glogster. Use the online software on the website the Glogster website to create your own digital poster about the water cycle.

Present the water cycle and its steps in an attractive online poster. You must include title, definition of the water cycle, each step discussed in class and its description, and a video that shows the water cycle .


View the following sample of a Glogster.

Please make sure you know how to embed pictures and video into a Glog. Ask your teacher or another student for help.

The Glog will serve as your assessment. For a sample of a Glogster rubric follow the link: Glogster Rubric (created by Folger Shakespeare Library, 2007 www.folger.edu/education).

Conclusion:

Good work! You have now identified and described the steps of the water cycle.

Now you can answer the question -- Where does the water come from and where does it go?
