Student Learning Objectives Upon viewing the video and completing the enclosed student activities, students will be able to do the following: • Understand that the water cycle involves the continual circular movement of water between Earth’s surface and the atmosphere. • Explain that in the process of evaporation a liquid changes into a gas. • Know that large amounts of water continually evaporate from lakes, rivers, and oceans. • Understand that water vapor is in the air around us. • List some common examples of water evaporating. • Define condensation as the process of a gas changing into a liquid. • Know that as water vapor rises in the atmosphere it cools and condenses into tiny liquid water droplets that form clouds. • Define precipitation as water that falls to Earth from the atmosphere. • List some examples of precipitation such as rain, snow, sleet, and hail. • Given a diagram of the water cycle, identify and explain the main parts.

Assessment

What Do You Know Now? (p. 10): This preliminary assessment is an assessment tool designed to gain an understanding of students’ preexisting knowledge. It can also be used as a benchmark upon which to assess student progress based on the objectives stated on the previous pages.

What Have You Learned? (p. 11):

This post assessment can be utilized as an assessment tool following student completion of the program and student activities. The results of this assessment can be compared against the results of the preliminary assessment to assess student progress.

Video Review (p. 12): The Video Review can be used as an assessment tool or as a student activity. There are two sections. The first part contains questions displayed during the program. The second part consists of a five-question video quiz to be answered at the end of the video.

Introducing the Program Before showing the video put a glass of water on a table in front of students. Ask them what would happen to the water in the glass over the next few days. Some students may think that some of the water will disappear. Explain that it will disappear over time. Write the term evaporation on the board. Then ask students when the last time they were in a rainstorm or snowstorm. Ask them where the snow or rain came from. Tell students that the rain or snow they experienced came from a cloud. And the water in the cloud evaporated from a lake, river, the ocean, or a mud puddle. Tell students to pay close attention to the video to learn more about how clouds form and the water cycle.

Program Viewing Suggestions The student master “Video Review” is provided (p. 12) for distribution to students. You may choose to have your students complete this Master while viewing the program or do so upon its conclusion. The program is approximately 10 to 12 minutes in length and includes a five-question video quiz. Answers are not provided to the Video Quiz in the video, but are included in this guide on page 9. You may choose to grade student quizzes as an assessment tool or to review the answers in class. The video is content-rich with numerous vocabulary words. For this reason you may want to periodically stop the video to review and discuss new terminology and concepts.

Video Script 1. Everyday you use water. 2. You use it to brush your teeth, 3. ...to wash yourself,... 4. ...to cook food,... 5. ...and to drink. 6. Water is very important, but have you ever thought about where water comes from? 7. What are some of the different forms of water? 8. And how does water move from place to place? 9. During the next few minutes we’re going to answer these questions, and others... 10. ...as we explore the water cycle. 11. Graphic Transition – What is a Cycle? 12. Maybe you enjoy riding a bicycle. 13. A bicycle has round tires. 14. The word “cycle” means round or circular. 15. The water cycle involves the continual circular movement of water between Earth’s surface, the atmosphere, and then back to Earth. 16. Let’s take a closer look at the different parts of the water cycle. 17. Graphic Transition – Evaporation 18. Have you ever noticed that puddles eventually dry up after a rain storm? 19. Maybe you’ve left a glass of water on a table and after a few days you noticed that some of it has disappeared? 20. You Decide! Where did the water go? 21. The water went into the air in a process called evaporation. 22. In evaporation a liquid changes into a gas. In this case, liquid water changed into water vapor. 23. Evaporation is a very slow process. So slow that you can’t actually see it taking place. 24. But you can tell that evaporation has occurred by seeing how the level of liquid water drops down over time. 25. On Earth, huge amounts of water continually evaporate from lakes, rivers, ponds, 26. ...and from the vast oceans. 27. Water vapor is all around you in the air at this very moment.

Video Script 28. You’re even breathing it in! 29. Graphic Transition – Condensation 30. We just discussed that the air around us contains water vapor. 31. It’s possible for water vapor to change back into liquid water. 32. Let’s see how. We’ll put a cold drink on this table and wait a few minutes. 33. You Observe! What formed on the sides of the glass? 34. That’s right, liquid water formed on the sides of the glass. 35. The water vapor surrounding the glass changed form into liquid water as it cooled in a process called condensation. 36. Condensation is the process of a gas changing into a liquid. 37. Clouds are formed as a result of condensation. 38. As water vapor rises in the atmosphere, it cools. 39. The cooled water vapor condenses into tiny liquid water droplets. 40. These tiny water droplets form clouds. 41. Graphic Transition – Precipitation 42. If you like to ski, snowmobile, or slide downhill then you enjoy snow. 43. Snow is a form of precipitation. 44. Precipitation is water that falls to Earth from the atmosphere. 45. Rain is also a form of precipitation. 46. You Compare! How is rain different from snow? 47. Rain is a liquid. Snow is water in the form of crystals. 48. Precipitation can also be in the form of sleet or hail. 49. Precipitation occurs when enough water has condensed in clouds to fall to Earth. 50. What happens to precipitation when it lands on Earth? 51. Once precipitation has landed on Earth it may flow into the ground, 52. ...or it collects in lakes, rivers, and oceans. 53. From these bodies of water it eventually evaporates, starting the water cycle all over again. 54. Graphic Transition – Video Review 55. During the past few minutes we explored the fascinating features of the water cycle.

Video Script 56. We began by discussing the many important ways that we use water. 57. Next, we saw how the water cycle involves the continual movement of water between Earth and the atmosphere. 58. We then discussed how liquid water changes into water vapor in the process of evaporation. 59. We saw how water vapor can change into liquid water to form clouds in the process of condensation. 60. Last, we took a look at how water returns to Earth from the atmosphere in the form of precipitation... 61. ...completing our investigation of the fascinating water cycle. 62. Graphic Transition – Video Quiz 63. Fill in the correct word to complete the sentence. 64. 1. The water ______ takes the form of a circle. 65. 2. In _______ water changes from a liquid to a gas. 66. 3. _____ can form as a result of condensation. 67. 4. Snow is a form of __________. 68. 5. _____ is liquid precipitation.
