  • Describe the process of energy transformation in your own words.
    Energy transformation is when energy is changed from one form to another.

  • Energy cannot be created or destroyed. True or false?
    True
  •  15
  • Name 3 types of renewable energy (energy that is not harmful to the environment)
    Example: Solar energy, geothermal energy, moving water, biomass
  •  15
  • Name 3 types of non-renewable energy (energy that can't be replaced once used)
    Example: burning of fossil fuels (coal, oil and natural gas), nuclear energy

  • What do we call energy produced by the sun that is very important for the biosphere?
    Light energy
  •  15
  • What do we call energy produced by the movement of tiny particles within an object?
    Thermal energy, or heat
  •  15
  • What do we call the stored energy that is released when a chemical reaction takes place?
    Chemical energy
  •  15
  • What do we call energy made by vibrations?
    Sound energy
  •  15
  • What energy is used by machines? Why?
    Electrical energy because it can be transformed into many different forms
  •  15
  • What do we call the energy stored in objects?
    Potential energy
  •  15
  • What type of energy is produced by movement?
    Kinetic energy
  •  15
  • Give an example of energy transformation
    E.g. When wood burns, chemical energy is transformed into light and thermal energy. E.g. A toaster transforms electrical energy into thermal energy
  •  15
  • What does renewable energy mean?
    Energy sources that will never run out. Most sources do not cause pollution and are not harmful to the environment.

  • What is this? What does it do?
    Turbines. It produces mechanical energy and converts it into electrical energy
  •  15
  • What is this? What does it do?
    Solar panel. It transfers solar energy into electrical energy.
