Time Required: 60 to 120 minutes
- Create a Cloud Chart blackline master from the JASON Mission Center.
- Make sure you have an Internet connection and projector to show the Clouds Gallery, and Fog, Dew, and Frost Gallery at the JASON Mission Center.
- Investigate the links suggested for the Art Connection on page 38 of the teacher’s edition.
- Investigate the additional links provided in Humidity on page 40 of the teacher’s edition.

- Ask students to recall the previous lab on the water cycle. Invite students to share the data they collected.
- Invite students to share responses to the JASON Journal prompt from page 35 of the student edition.
- Explain that today’s lesson will focus on how the water cycle plays out in the earth’s atmosphere to create weather events.
- Download the Robbie Hood podcast described on page 41 of the teacher’s edition.

- Ask students to recall their work from the Phase Changes of Water article on page 31 of the student edition. Recall which terms went in the “absorb energy” and “release energy” columns.
- Ask students to read How Energy and Water Interact in the Atmosphere on pages 36 and 37 of the student edition and follow the discussion prompts provided on page 36 of the teacher’s edition.
- Invite students to draw a simple model of the water cycle, as demonstrated in Lab 1, and use it to summarize how heat and water interact.
- Next, have students turn to page 38 of the student edition and read Understanding Clouds. The introduction and discussion questions provided on page 38 of the teacher’s edition provide excellent guidance.
- Distribute the Clouds Chart blackline master and have students complete the chart as they read. This will reinforce the information in the article.
- Display pictures from the Clouds Gallery as suggested on page 38 of the teacher’s edition.
- Continue the study of water in the atmosphere by reading Fog, Dew, and Frost and Measuring Water Vapor in the Air on pages 39–41 of the student edition. Follow the guided questions suggested on page 39–41 of the teacher’s edition.
- Display pictures from the Fog, Dew, and Frost Gallery to check students’ understanding of the concept. Ask students to write the steps that contribute to the formation of fog, dew, and frost.
- Draw a triple Venn diagram on the board and write ”humidity,” “absolute humidity,” and “relative humidity” in each of the three circles. After students have completed the article, compare and contrast these terms. Make sure that students have clearly defined these terms in their notebooks.

Scientists use the word humidity to describe how much water vapor is in the air. Humidity depends on air temperature and the amount of liquid water available to evaporate into water vapor. Read this article to find out about the various ways scientists measure the amount of water vapor in the air, and how these measurements relate to weather forecasting. |

Reflect And Assess |
|
|
|
|
- Collect the Clouds Chart blackline master for immediate assessment.
- Give a short open-note quiz on the terms discussed during class.
- Discuss why you can see your breath on a cold day as described in Reteach on page 37 of the teacher’s edition.
|
|
|
|
 |
Follow-up |
|
|
|
|
- Use the JASON Journal Prompt on page 40 of the teacher’s edition to reinforce water vapor measurements.
- Ask students to respond to the Critical Thinking question on page 37 of the teacher’s edition.
- Consider assigning the Art Connection on page 38 or the Humidity Investigation on page 40 of the teacher’s edition to selected students as long-term projects.
