Maths KS2: How to measure temperature and save energy

Stefan Gates visits the Royal London Hospital in London where he learns about measuring and controlling temperature.

He reads the story of ‘Goldilocks and the Three Bears’ to a group of children.

He learns about temperature by measuring three bowls of porridge using a thermometer and finds out why it is important that children who are sick are “not too hot, not too cold but just right”.

Then he discovers that in the old children’s ward they control the temperature by opening the window!

In the new hospital they use a computer to monitor and control temperature to ensure that the whole building is always the right temperature and they don’t waste energy.

Stefan then visits Glenfrome Primary in Bristol where they have a 'coolest class’ challenge.

They keep doors and windows closed and turn radiators down to make sure classrooms stay at a more consistent and comfortable temperature.

They gather data that they then turn into charts so that they can understand which is the best class on saving energy.

Teacher Notes

Discuss what temperature is just right for your classroom.

Is the ideal temperature the same for all the rooms in the school?

Collect real data on the temperature in different places around your school, then sort it, create graphical representations and interpret your results.

Could your school be more energy efficient? Compare the results you find in your school with the results from Glenfrome Primary.

Ask the children if they think the staffroom is too hot to start a discussion on interpreting the data.
