Lesson 4 - SDG Climate Action: Design & Build a Wind Power System Model
1. Engage: Power All Around Us – Generate to Use!
Start with a quick, relatable poll:
Raise your hand if you charged a phone, used a toaster, or turned on a light this morning. All those need electricity! But where does it come from? And how does it get transmitted?
Key Question
How electricity reaches your home?
Activity 1
Sort the following steps in order.
Today, we’ll design and build a wind power system model with storage, just like real-world renewable energy setups helping with SDG 13 Climate Action!
2. Explore: Electricity Supply vs Demand – The Gap Challenge
Wind doesn’t blow exactly when we need power. For example, wind often picks up at night, but we use more electricity in the morning (making breakfast, charging devices) and evening (cooking, watching shows).
Note: The unit of electricity is arbitrary and for simulation only
Activity 2
Give each group a simplified data table (The data in the table are simulated and for reference only.):
Ask students draw a line graph with two lines: one for supply, one for demand.
Cut and stick the graph on your group’s project board.
Share & Discuss
When does wind supply exceed demand? (20:00-4:00)
When do we need more power than the wind can provide? (8:00-16:00)
Key Question
How do we keep extra wind power for later?
3. Investigate: Battery Banks – The Energy Storage Superheroes
When wind generates more electricity than we use, large-scale battery banks store that extra energy for later!
Let’s uncover the superpowers of battery banks!
Activity 3
In small groups, use guided prompts to investigate (Provide each group with printed fact sheets about battery banks, or allow 5 minutes of guided online research):
Function: What do battery banks do? (Store excess wind energy, release it when demand is high)
Advantages: Why are they better than wasting extra electricity? (Reduces reliance on fossil fuels, keeps electricity available when wind is calm, cuts energy waste)
Real-Life Example: Name one place that uses big battery banks with wind turbines (e.g., Hornsea Wind Farm in the UK).
Each group shares 1-2 key findings with the class.
4. Design: Sketch Your Wind Power System
Activity 4
Each group draws a simple diagram of their wind power system, labeling these parts on the diagram:
1.Wind speed simulation adjuster
2.Electricity Generation
3.Battery banks
4.Customer use
Key Question
What are the simulation rules? (When the turbine spins fast, the battery charges; when we turn on the LED, battery power is used)
5. Build: Assemble Your Wind Power Model
Assemble your wind turbine system on the background board.
Today, we learned that wind power supply and demand don’t always match, discovered how battery banks solve this problem, and built our own mini wind power system! This is exactly what renewable energy engineers do to reduce fossil fuel use and fight climate change. Next lesson, we’ll make our model store and use electricity. Let’s keep building a greener planet!
