MS-ESS2-1, as students are working to understand how water is cycled throughout our planet.
Using online media and demonstrations, students use their information about phase changes to identify the parts of the water cycle.

students spend time in small groups (3-4 students) and analyze a diagram of the water cycle. They will be guided by the questions in the notes sheet.  They should be familiar with the phase changes of matter to complete this activity. The notes sheet reads as follows:
Using the water cycle diagram, answer the questions below.
1.What is evaporation?
2. What would be the source of heat in nature?
3.What is condensation?
4.What is precipitation?
5.What causes evaporation to occur again?

Next, I show the students a video for them to see the water cycle in action.  I preview the video by reading the questions in the explain section of the notes sheet aloud with them:
I use a BrainPop Jr. Water Cycle* video, which requires an account, and students view it to answer the questions below.

1. Water vapor is what form of matter?

2. How are clouds formed?

3. Rain, snow, sleet, and hail are called what?

4. In your own words, what is the water cycle?

As a class, we will go over the responses to be on the same page up to this point.
* This video can easily be replaced with another resource that covers:
- How water moves.
- What powers this water cycle.
- Why scientists study it.
How surface water gets into the atmosphere and how water vapor condenses to form clouds.
o How long has the water cycle been going on, and how much time does water spend in each part of it?
o Groundwater--what it is and why we depend so much on it.

Home page for the Water Cycle topic.This website, presented by NASA's Global Precipitation Measurement (GPM) mission, provides students and educators with resources to learn about Earth's water cycle, weather and climate, and the technology and societal applications of studying them.

Students need a laptop or device with internet access to complete this section of the lesson. In small groups, they work to complete the chart below by following the prompts on the site. Or, you can have students complete it individually if you have a class set of laptops:
Students use an EPA Water Cycle demonstration to help them to complete the chart.

For the last task, students will label the water cycle image below on their notes sheet:
Label the parts of the water cycle below, using words from this list- evaporation, condensation, precipitation, transpiration.
