Energy Transformations KWLH Chart

You are on a space mission with Bodhi, Talia and Harper-Mae. Your task is to investigate how energy changes from one form to another. Complete the KWLH chart using what you know, what you wonder, what you learn from the mission notes, and how you could investigate further.

Mission notes: energy changes

Energy can be transferred or transformed. In a solar panel, light energy from the Sun changes into electrical energy. The spacecraft’s motor changes electrical energy into movement (kinetic energy) and some sound and heat. A cabin lamp changes electrical energy into light and heat. A battery stores chemical energy, which can be changed into electrical energy when it powers a device.

1.Bodhi checks the spacecraft’s solar panels. Which energy transformation takes place in a working solar panel?
  • Light energy changes into electrical energy.
  • Electrical energy changes into chemical energy.
  • Kinetic energy changes into light energy.
2.Talia switches on the spacecraft’s electric motor. Complete the chain: electrical energy changes mainly into energy, with some energy also becoming sound and heat.
3.Harper-Mae switches on a cabin lamp. Which forms of energy does the lamp produce? Select all that apply.
  • Light energy
  • Heat energy
  • Kinetic energy
  • Chemical energy
4.Bodhi says, “The motor makes energy from nothing.” Is Bodhi correct? Explain what happens to the energy instead.
5.Write one fact you already know about energy transformations. You may use an example from the spacecraft or everyday life.
6.Write one question you would like to investigate about energy transformations on the mission.
7.Use the mission notes to write one new fact you learned about an energy transformation.
8.Describe one safe way to find out whether a solar panel produces more electrical energy in brighter light. Name what you would change and what you would measure.
9.Complete the spacecraft power chain in order: sunlight → solar panel → energy → motor → energy (movement).
