Worksheet for children to learn about sources of energy, matching images to words like electricity, sun, battery, man, and fuel.

This is a worksheet for children titled "Where Does Energy Come From?". The task is to match each of the nine pictures with one of the five energy sources listed at the top: electricity, sun, battery, man, or fuel.

To solve this, I will analyze each picture and determine its most direct source of energy based on common knowledge. I'll go through them row by row.

First Row:
- Car (Jeep): This is a vehicle that typically runs on gasoline or diesel, which are forms of fuel.
- Airplane: Like the car, an airplane uses jet fuel to fly, so its energy source is fuel.
- Lightbulb: A standard lightbulb is powered by electricity from a wall outlet.

Second Row:
- Flashlight: This device is powered by battery.
- Tree: Trees get their energy to grow through photosynthesis, which comes from the sun.
- Scissors: Scissors are a tool that requires human effort to operate, so the energy source is man.

Third Row:
- Hairdryer: This appliance plugs into an electrical outlet, so it runs on electricity.
- Flower: Similar to the tree, a flower gets its energy for growth from the sun via photosynthesis.
- Bicycle: A bicycle is powered by the pedaling of a person, so the energy source is man.

Now, I will compile these answers to complete the worksheet.

First Row:
- Car: fuel
- Airplane: fuel
- Lightbulb: electricity

Second Row:
- Flashlight: battery
- Tree: sun
- Scissors: man

Third Row:
- Hairdryer: electricity
