Energy

Join the fun in KS2 Science with this quiz exploring energy in its different forms like heat, light, and movement!

Energy is power that makes things happen. Every action needs energy, even blinking! It's not just in food or fuel; everything has energy. Heat, light, sound, moving, electricity - all types of energy! It can't be made or vanish but can change forms. We talked about heat, light, sound, movement, and electric energy, but how many more do you know? What unit measures energy? What's the name for solar electrical energy? Find out in this cool science quiz!

Boost Your Child's Confidence with Quizzes
1.
Children skipping rope are converting stored energy (from the food they've eaten) into which form of energy?
Potential energy
Light energy
Kinetic energy
Nuclear energy
Kinetic means 'movement'
2.
Stored energy is called what?
Electrical energy
Potential energy
Kinetic energy
Saved energy
'Potential' means 'possible'. Potential energy can become another form of energy, such as kinetic. A stretched spring would contain potential energy
3.
Which of these is not an example of kinetic energy?
A moving bicycle
The second hand of a clock moving
Someone rowing a boat
Wood stored in a woodpile
Wood is an example of stored, or potential, energy
4.
What do we call electrical energy which comes from sources such as the Sun, the wind or waves?
Non-renewable energy
Renewable energy
Nuclear energy
All of the above
The wind, the waves and the Sun will not run out for billions of years and so they are renewable
5.
What happens to the energy you store in your body?
It disappears
It is used up
It changes into other forms of energy
It is lost
Energy cannot be created or destroyed, but it can change into other forms - this is called the 'Law of Conservation of Energy' - did you know that most of your body's energy is converted to heat?
6.
Energy is measured in what?
Degrees Celsius
Metres
Grams
Joules
Degrees Celsius measure temperature, metres measure distance and grams measure mass or weight
7.
Which of these is not a form of energy?
Kinetic (motion)
Thermal (heat)
Chemical
Power
'Power' is often used as another word for 'energy', but it is not a form of energy. Other forms of energy include: radiant (light), electrical, nuclear and gravitational potential energy
8.
What do we call fuel sources such as coal, oil and natural gas?
Non-renewable energy sources
Renewable energy sources
Nuclear energy
Radiant energy
Coal, oil and natural gas are all 'fossil fuels' that took millions of years to form under the ground. Because they cannot be easily replaced, they are called 'non-renewable' energy sources
9.
Which of these is not an example of potential energy?
A car at the top of a hill
A beam of light from a torch
A stretched rubber band
A diver on the edge of a diving board
A beam of light is radiant (light) energy
10.
In order to work, a toaster needs what?
Electrical energy
Chemical energy
Kinetic energy
None of the above
A toaster uses electrical energy, which it converts to heat and light - you use kinetic energy when you put the bread in the toaster and press the lever
