The lesson uses the story "Drippy the Raindrop" to teach kindergarten students about the water cycle. The teacher will read the story aloud and prompt students to pay attention to Drippy's journey through the stages of the cycle. Then, students will help create a poster mapping out the places Drippy visited. Finally, the class will learn a song reinforcing the water cycle stages. The goal is for students to understand the water cycle, and the objective is for them to follow Drippy's journey through each stage.
