THINKING TASK: Match the following. What energy transforms to another...

• Sun (radiant) energy

• Chemical energy

• Chemical Energy

• Chemical Energy

• Electrical energy

Turns into Chemical energy for Plants

Turns into Mechanical for Cars

Turns into mechanical for human moving

Turns into radiant for flashlight

Turns into heat energy for toaster

• Turns into Chemical energy for Plants

• Turns into Mechanical for Cars

• Turns into mechanical for human moving

• Turns into radiant for flashlight
