The Water Cycle
Learning Objectives
- Describe the stages of the water cycle, including evaporation, condensation, and precipitation.
- Explain how heat from the Sun drives the water cycle.
- Identify the forms of precipitation and how they return water to Earth's surface.
- Understand the continuous nature of the water cycle and how water moves between Earth's surface and the atmosphere.
Introduction and Hook
Engage students with a short video on the water cycle to visually introduce the stages of evaporation, condensation, and precipitation.
Direct Instruction
Explain each stage of the water cycle in detail, emphasizing the processes of evaporation, condensation, and precipitation. Highlight how the Sun's heat drives these processes.
Use diagrams and illustrations to show how water moves between the Earth's surface and the atmosphere, reinforcing the continuous nature of the water cycle.
Guided Exploration
Watch the video 'Understanding and Measuring Weather' to explore how weather patterns are influenced by the water cycle and the Sun's heat.
Facilitate a discussion on different forms of precipitation and how they return water to Earth's surface, encouraging students to share observations from their own experiences.
Hands-On Activity
Conduct a simple experiment to demonstrate evaporation and condensation using a kettle and a mirror. Have students observe and record their findings.
Guide students in creating a mini water cycle model using a plastic bag, water, and a sunny window to observe evaporation and condensation over time.
Independent Practice
Assign the 'Observing the Weather' assessment where students record daily weather conditions and analyze patterns over two weeks.
Check for Understanding
Use questioning techniques to assess students' understanding of the water cycle stages and the role of the Sun in driving these processes.
Have students label a diagram of the water cycle, identifying key processes and forms of precipitation.
Review and Reflection
Encourage students to reflect on what they have learned about the water cycle and its importance in the Earth's ecosystem.
Facilitate a class discussion on how human activities can impact the water cycle and what measures can be taken to protect it.
Assessment and Extension
Administer the 'The Water Cycle' assessment to evaluate students' comprehension of the water cycle's stages and processes.
Encourage students to take the unit quiz to test their overall understanding of the Weather and Climate unit.
