🎯 Our mission

Rescue workers need light after a storm. Build a system that can make a bulb shine. Make a prediction, test it, and explain what happened.

1 · CHOOSEPick where the energy starts.

2 · CONNECTMake a complete path.

3 · TESTCheck the bulb and record evidence.

🔧 Build your system

Energy source

How fast do you turn the crank? 50% 0 = not moving | 100 = very fast

Wires connected

Switch closed (ON)

Tip: Change ONE part each time. Then test again. Reset turns everything off and sets both power levels to zero.

Ready to test.

Choose your parts. Then press TEST MY SYSTEM.

Simplified model: the hand crank turns a generator that converts motion into electrical energy. The battery provides stored chemical energy. The wires and switch complete the circuit. Real systems also lose some energy as heat.

🧪 Try these three tests

Challenge 1Hand crank + wires connected + switch ON. Turn the crank. Can you light the bulb?

Challenge 2Keep turning. Open the switch. What happens?

Challenge 3Close the switch. Turn the crank slowly, then quickly. What changes?

📝 Record your evidence

Student name Class (optional)

1. What did you change?

2. What happened to the light?

3. Explain: How did the parts work together?

You can also draw your answer or tell your teacher/partner. Every scientist needs evidence!

🗣️ Turn & Talk

Did the generator CREATE energy, or CHANGE energy from one form into another?

Sentence frame: “I think the generator ______ energy because ______.”

Teacher: show the science explanation

Generators convert mechanical energy into electrical energy; they do not create energy. A broken circuit stops current, even while the crank turns. A brighter bulb in this simplified model indicates more electrical power supplied by faster cranking.
