  • We can use geothermal energy from the sun to do many things.
    False
    True
  • How does moving water create energy?
    It spins turbines to generate hydropower.
  • What is the primary source of light energy on Earth?
    the sun
    fire
    the earth
    the moon
  • Does hydropower cause pollution?
    No, but it can affect the habitats of aquatic species.
  • How is sound energy created?
    By the reflection of light
    By the vibration of objects and air particles
    By the movement of electrons
    By the transformation of heat energy
  • How is thermal energy, or heat, generated?
    Through the absorption of sound waves
    By the release of chemical energy
    By the movement of tiny particles within an object
    By the presence of light energy
  • What is uranium?
    A non-renewable energy source used in nuclear power stations to produce electricity.
  • Oil, coal and natural gas are all forms of energy.
    True
    False
  • What do wind turbines produce before converting it into electrical energy?
    Mechanical energy.
  • What is the biggest risk of using nuclear power?
    The radioactive waste it produces, which is dangerous to humans and the environment.
  • Why are renewable energy sources good for the environment?
    They do not cause pollution and are not harmful.
  • How did fossil fuels form?
    Over millions of years, heat and pressure turned decaying material into coal, oil, or natural gas.
  • Transforming chemical energy into electrical energy isn’t useful to us.
    True
    False
  • Energy makes changes and movement possible.
    False
    True
  • What is geothermal energy?
    Heat energy that comes from the Earth's core.
  • What is biomass energy made from?
    Trees, plants, and rubbish.
  • Fossil fuels are renewable energy sources.
    True
    False
  • Energy can be created, destroyed and transformed.
    True
    False
  • What type of energy is produced by movement?
    Kinetic energy
  • Energy is continually transformed.
    False
    True
  • What energy transformation occurs in a toaster?
    Electrical energy is transformed into thermal energy.
  • What is energy transformation?
    The process of changing one form of energy into another.
  • There are some energy sources that will never run out
    True
    False
  • Why are fossil fuels non-renewable?
    They take millions of years to form and cannot be replaced once used up.
  • What is electrical energy used for?
    To store food
    To make objects heavier
    To power machines
    To create sound
  • What happened to dead plants and animals?
    Their remains settled on the ocean bed and in swamps, then got covered by sediment.
  • Energy makes changes and movement possible.
    False
    True
  • What are fossil fuels?
    Coal, oil, and natural gas.
  • What does chemical energy do in the context of food?
    It is stored and released when the body digests food
    It creates vibrations that produce sound
    It absorbs light energy for growth
    It produces heat in cold environments
  • What type of energy transformation happens when wood burns?
    Chemical energy is transformed into light and thermal energy.
  • The lighter an object is and the faster it moves, the more kinetic energy it has.
    True
    False
  • What happens when oil spills into the ocean?
    It causes serious environmental problems and harms marine life.
  • How does burning fossil fuels harm the environment?
    It contributes to global warming, causes air pollution, and leads to acid rain.
  • When you jump off a diving board, what energy transformation happens?
    Potential energy is transformed into kinetic energy.
  • Burning fossil fuels can cause acid rain to fall.
    True
    False
  • What type of energy is released when a chemical reaction takes place?
    Mechanical energy
    Light energy
    Chemical energy
    Sound energy
  • Radioactive waste is a big risk of using nuclear power.
    True
    False
  • Where is potential energy stored?
    In objects that are still
    In sound waves
    In moving objects
    In food only
  • How do we get fossil fuels today?
    We drill and mine them from the Earth.
  • What covered the Earth millions of years ago?
    Swamps with giant ferns and trees.
  • What device is used to transform solar energy into electrical energy?
    Solar panels.
  • What is renewable energy?
    Energy that comes from sources that will never run out.
  • When mechanical energy is released, it can do work.
    False
    True
  • When energy transformations are useful, we say the energy is lost or wasted.
    True
    False
  • Although we may not notice, energy is all around us.
    True
    False
  • Can energy be created or destroyed?
    No, energy can only be changed from one form to another.
  • Why is a bow and arrow an example of mechanical energy?
    Because it stores potential energy and releases it as kinetic energy
