You are an experienced instructional designer. Develop a 45-minute lesson plan for a 5th-grade science class about the water cycle. The plan should include: 1. Clear learning objectives. 2. A list of required materials. 3. An engaging hook to capture students' attention. 4. A main activity (e.g., a hands-on experiment or diagramming task). 5. A method for assessment (e.g., exit ticket questions). 6. Differentiation ideas for struggling students and advanced learners.
