Saving Energy: Key Stage 2

Schools and Education > Saving Energy: Key Stage 2

The topic of saving energy is introduced in this learning resource for KS2 / primary level pupils.

The following lesson plan will introduce the topic of saving energy to primary (Key Stage 2) level pupils. It supports a number of topics within the NI Curriculum and the Primary School Curriculum in the Republic of Ireland, including aspects of The World Around Us Area of Learning (NI Curriculum) and the Environmental Awareness and Care Strand (R.O.I. Primary Curriculum).

  • This lesson links to the Energy Saving Trust’s video on Energy Saving Lighting.
  • The lesson is designed to be used in conjunction with the saving energy information sheet and activity sheet, both of which can be downloaded below.
  • Words in bold are ‘keywords’ which may need to be defined for pupils.
  • There is a link to an interactive quiz which will test what the pupils have learned about saving energy during the lesson.
  • At the end of the lesson are a number of suggestions for follow-up activities on saving energy.

Lesson Plan:


  • Pupils will discuss the importance of electricity in their everyday lives.
  • Pupils will be aware that electricity is made in a fossil fuel power station.
  • Pupils will know that pollution is a consequence of burning fossil fuels.
  • Pupils will understand how pollution can be harmful to our environment.
  • Pupils will learn how we can reduce pollution by saving energy.
  • Pupils will be able to distinguish between ordinary light bulbs and energy saving bulbs.
  • Pupils will consider a number of ways to save energy at home.


Introduce the lesson by asking the children to work together in groups to write down all the items they can think of which use electricity in their homes. Ask pupils to write these in a list at the front of the room. Discuss how nowadays we take our electricity supply for granted, and ask if pupils know where our electricity comes from. Describe how electricity is made in a power station by burning fossil fuels like coal, oil and gas. Explain that these fuels have taken millions of years to form, and that when burned they release pollution into the atmosphere. This pollution can harm the environment by causing global warming and acid rain. Then ask the pupils if they can think of ways to reduce this pollution. Explain that by saving energy at home, power stations will produce less electricity and therefore release less pollution. Ask the pupils to read through the saving energy information sheet.

Lesson Development

Show the class an ordinary light bulb and an energy saving bulb. Ask how many of them have energy saving bulbs in their home, and if they know the difference between the two types. Show the class the Energy Saving Trust’s video on energy saving lightbulbs by clicking on the image in the right hand column. Ask the pupils to complete the saving energy activity sheet. Go over the answers to each of the questions with the class. Make a list of all the pupils’ methods of saving energy at home.


Recap on the lesson with the class. Discuss the different ways to save energy at home, and ask the class how many of them try to save energy in their homes. Encourage the class to take the energy saving message home to their parents.

Ask the pupils to test their knowledge of saving energy by taking the quiz in the right hand column.

Follow up Activities

  • Pupils take the interactive quiz on saving energy.
  • Pupils watch the Energy Saving Trust video on loft insulation.
  • Pupils use the sustain and build website to research other ways to save energy.
  • Pupils work in groups to design posters encouraging people to save energy at home and around the school. They give a presentation on these to the rest of the class.
