Pico Technology Science experiment: Investigating Heat Loss Due to Radiation using DrDAQ as a Temperature Probe

Educational data logger


DrDAQ is being used here as a dual temperature probe. In both KS3 and KS4 science students have to be aware of the heat loss from objects due to radiation. Radiation is an electromagnetic wave which can travel through a vacuum. You cannot see it with the human eye but the fire brigade use special cameras which can see this type of radiation. All hot objects will lose energy in this way. In hot countries the people wear light coloured clothes and if you wear black on a hot day you seem to feel hotter. This experiment is examining whether colour can effect how heat is lost

Carrying out the Experiment

Safety is paramount here. Take great care when transferring and handling boiling water. I suggest clamping the flasks down to avoid the risk of spillage.

Questions & discussion of results

  1. Which flask dropped in temperature the quickest? Quote results to prove your point
  2. Can you suggest a link between the colour of the flask and how quickly the heat was lost?
  3. Use textbooks and/or the internet to find some scientific reasons why one coloured flask cooled more quickly than another.
