  • What do we call energy made by vibrations?
    Sound energy
  • What do we call energy produced by the sun that is very important for the biosphere?
    Light energy
  • Where is uranium energy made? What happens?
    In nuclear power stations. They transform the chemical energy in uranium into electrical energy.
  • 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
  • What is the problem with creating hydropower energy from moving water?
    It affects the habitats of aquatic species.
  • What does non-renewable mean?
    Natural energy sources that cannot be replaced once they have been used up e.g. fossil fuels (coal, oil, natural gas)
  • What energy source is this an example of?
    Mechanical energy
  • What is biomass?
    Biomass is a way to use trees, plants and rubbish to make energy.
  • What energy is used by machines? Why?
    Electrical energy because it can be transformed into many different forms
  • What is this? What does it do?
    Solar panel. It transfers solar energy into electrical energy.
  • What is the biggest risk of using nuclear power?
    The radioactive waste it produces.
  • Describe the process of energy transformation in your own words.
    Energy transformation is when energy is changed from one form to another.
  • What type of energy is this?
    Geothermal energy
  • What do you think is better to use: Renewable or Non-renewable energy? Why?
    Student answer
  • What do we call the stored energy that is released when a chemical reaction takes place?
    Chemical energy
  • Is uranium energy renewable or non-renewable?
    Non-renewable
  • What does the burning of fossil fuels cause?
    It contributes to global warming and causes air pollution. The pollution from power plants and factories rises into the atmosphere and falls as acid rain.
  • Energy cannot be created or destroyed. True or false?
    True
  • What type of energy is produced by movement?
    Kinetic energy
  • What do we call the energy stored in objects?
    Potential energy
  • 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 is this? What does it do?
    Turbines. It produces mechanical energy and converts it into electrical energy
  • What is the biggest risk associated with transported oil?
    When it spills into the ocean, it causes serious problems.
  • 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.
  • Name 3 types of renewable energy (energy that is not harmful to the environment)
    Example: Solar energy, geothermal energy, moving water, biomass
  • What do we call energy produced by the movement of tiny particles within an object?
    Thermal energy, or heat
