Lesson Plan

• Describe the main types of water resources and their contribution to global freshwater supply.
• Explain the primary functions and key management challenges for each water resource.
• Analyse the connections between resources within the water cycle and apply the water‑balance equation.
• Evaluate how climate change influences the availability and reliability of each resource.

• Projector and digital slide deck
• World map or GIS printout
• Fact‑sheet handouts for each water resource
• Worksheet with water‑balance problems
• Markers, chart paper, and sticky notes
• Water‑cycle diagram handout

Begin with a striking statistic about global water scarcity to hook interest. Ask students what they already know about the water cycle from the previous lesson, then outline today’s success criteria: identify each water resource, explain its uses and challenges, and link it to the water‑balance equation.

1. Do‑now (5') – Quick quiz on the percentage of Earth’s water that is freshwater.
2. Mini‑lecture (10') – Slide presentation covering the seven water resources, highlighting key functions and issues.
3. Group activity (15') – Each group creates a “resource card” summarising uses, benefits, and management challenges for an assigned resource.
4. Whole‑class discussion (10') – Groups share cards; teacher facilitates comparison and links to the water cycle.
5. Application exercise (10') – Students solve a water‑balance problem using provided precipitation data.
6. Exit ticket (5') – One‑sentence response: “Which water resource is most vulnerable to climate change and why?”

Recap the main functions and pressures of each water resource and how they interrelate within the cycle. Collect exit tickets to gauge understanding, then assign homework: research a local water‑resource management case and prepare a brief summary for the next lesson.
