Goal: Build a simple dynamo-powered light that turns on when you pedal your bike!
🔬 Science Behind It:
- Energy Conversion – The bicycle’s movement creates mechanical energy, which is converted into electrical energy using a dynamo.
- Electric Circuits – The dynamo generates electricity to power the LED light.
- Physics of Motion – Faster pedaling creates more electricity!
🛠️ Materials Needed:
✔️ A bicycle 🚲
✔️ A small dynamo generator (available at electronics shops) ⚡
✔️ LED light 💡
✔️ Wires & connectors
✔️ Tape or zip ties
🔧 How to Build It:
1️⃣ Attach the Dynamo – Fix the dynamo to the side of the bicycle wheel so that it spins when you pedal.
2️⃣ Connect the Wires – Attach wires from the dynamo to the LED light.
3️⃣ Secure the Light – Mount the LED near the handlebar so you can see it glow!
4️⃣ Test It Out! – Start pedaling and watch the light turn on!
💡 Extensions & Challenges:
🔹 Can you power a small fan or phone charger instead of a light?
🔹 Experiment: What happens when you pedal faster or slower?
🔹 Measure the voltage produced using a multimeter.
🚴 What Kids Learn:
✅ How energy is converted from motion to electricity.
✅ Basics of electric circuits and how a dynamo works.
✅ The importance of renewable energy and sustainable transport.
