Introduction (5 minutes)
- Gather your students somewhere where they can all see you.
- Tell your students that you are sad because a glass of water fell on your favorite shirt.
- Pull the wet shirt out of your bag and show it to them.
- Pretend to be upset about the shirt being ruined.
- Tell your students that you will have to throw it away.

- Ask your students what it means for something to dry.
- Ask your students where the water goes when something is drying.
- Tell your students that they will be learning about where water goes in the water cycle.

- Ask your students what a wheel does on a bike.
- Explain to students that water goes in a cycle just like a wheel goes around and around.
- Instruct your students to watch The Water Cycle.
- Read the text as it appears in the video.
- Pause where necessary to elaborate or discuss what is meant by the text.
- Pay particular attention to the water cycle vocabulary: evaporation, condensation, precipitation, and collection.
- Use a glass of ice water as an example for condensation and collection and a glass of boiling water for evaporation if your class needs more help.
- Watch Water Cycle Song and have your students sing along.
Guided Practice/Interactive Modeling (5 minutes)
- Hand out the Water Cycle Diagram worksheet.
- Tell your students to sit in a circle with the diagram on the floor in front of them.

- Instruct your students to raise their hand as them finish the assignment.
- Go to each student as they finish and ask them to point to and describe the parts of the water cycle on their diagram.
