1. Introduce Our Kit and Science groups What’s in our kit? Complete anticipation guide Assign groups and jobs Complete KWL (K and W only) Introduce Vocabulary Salt water (97.2%) vs. fresh water (2.8%)

2. Water in different forms Photo Cards Answer questions and discuss Explain Cycles

3. Stream Tables and the Water Cycle Read “Tapping into the Water Cycle” Answer questions and discuss. Introduce Vocabulary

4. Examine Earth Materials Steps to complete: Distribute Earth Materials, Hand Lenses, Spoons, and Record Sheet 5-A. Examine Materials through sight and touch, recording your findings. Discuss as a group.

5. Water Cycle Steps to complete: 1. Bulldoze soil. 2. Add warm water. 3. Cover with saran wrap and rubber band. 4. Place ice pack over warm water. Questions to think about: After conducting this lab, what do we know about rain? What do we know about how water meets land? Discuss Closed Cycles Model by placing a large leaf in a Ziploc in the sun

6. Rain on Land 1.Model By Teacher 2.Experiment with your Stream Tables! Questions to think about:  What are some changes in the land you noticed as you made it rain? Why do you think this happened?  What happened as the rain hit the land?  Where did the water go?  Compare the water in the bucket with the water you used to make rain. How are they different? Why do you think so?  In what ways would a heavy rain storm affect land differently? Why?

7. Rivers Steps to complete: Create a River Bulldoze. Use the cup with the small hole to create your river. Questions to think about: What did you observe about the soil components in your stream table? What is the length of your stream? What is the length of your soil block? Are they the same? Why or Why not? Collect a water sample. Complete Record Sheet 4-A. (measure river using string) Vocabulary (Parts of a river)

8. Review Review Lessons 1-5. Read “Where does Drinking Water Come From?” and discuss. Vocabulary.

9. Testing Pore Space Steps to Complete: (Using Record Sheet 6-A) Compact 20ml of each earth material into a graduated cylinder. Predict the total volume after adding 30ml of water to each cylinder. Add 30ml of water to each cylinder and answer questions 5-7. Discuss Findings.

10. Where Does the Soil Go? Steps to complete: Create a stream and observe/mark rate of flow using flags. Questions to think about: Where was the most soil worn away or eroded? Where in your stream table was the most soil deposited? How does the slope of the land affect the amount of soil that is eroded or deposited by water? Which soil components are deposited first? Why do you think so?

11. The Parts of a Stream Review Vocabulary Draw a Bird’s Eye View of your stream. Questions to think about: How is your Bird’s Eye View different from pictures you usually take or see? How do you think this kind of picture could be used?

12. Modeling Tributaries Steps to complete: Create a stream using cup with 3 holes. Draw the path of the water and land. Questions to think about: How were our streams today different than in other labs? What happened when several streams flowed at the same time? Use evidence from your stream to support your answer. Look at the deposition at the end of the stream. How is it different from other labs? Why?

13. Rushing Rivers Steps to complete: Create a stream using the cup with a large hole. Collect a water sample. Questions to think about: How did the water in today’s lab change the land? Why do you think this happened? Compare the length and width of the river from today’s lesson and lesson 4. How are they different? How were they the same? What effect does a large amount of rapidly flowing water have on the amount of soil is eroded or deposited?

14. Hills and Rocks Steps to complete: Place rocks and make hills in stream table. Predict how this will change the flow of water. Experiment with your stream tables! Questions to think about: How did the rocks and hills change the direction and flow of water? Did the water affect the hills? If so, how?

15. Dams Google Earth Hoover Dam Read “Releasing a River” Record Sheet 12-A

16. Dams Continued Steps to complete: Set up stream table according to Record Sheet 12-A. Make Predictions. Flow water (Observe each groups dam). Discuss

17. Exploring Slope Steps to complete: What else could we do to our stream tables to explore the effects of water on land? Slope your stream table and experiment! Collect a water sample. Record Observations on Record Sheet 4-A. Questions to think about: In what ways did the water change the sloped land? How did the slope affect the way the water moved? Look at the cylinders of runoff and compare the amount of soil in each one. Are they different? Why do you think so? Plant grass for next lab.

18. Investigating With Plants Steps to complete: How do you think grass will change the effects of water on land? Experiment with your stream tables! Complete Record Sheet 14-A and compare samples (before and after plant removal). Questions to think about: How did plants affect the way water flowed on the sloped land? How did plants affect the way the water eroded the soil?

19. Design a Neighborhood Design your own neighborhood using the information you have gathered throughout this science unit. Your neighborhood should be able to withstand a large amount of rain. What could you do to ensure that your neighborhood does not become adversely affected by flood situations?

20. Review Review entire unit. Key Vocabulary and concepts
