Is My Teacher “Hot”?
“Is my teacher ‘hot’?” is not a question students often ask at school, but it would have been entirely appropriate for a session on infrared organised by Dr Jared Lewis at John Masefield High School recently. David Whitaker and John Gillham visited the school to talk to the Year 10 triple science students about infrared. Infrared is a part of the electromagnetic spectrum, beyond red visible light, that we sense as heat.
David and John are founder members of the Malvern Radar And Technology History Society (MRATHS – http://mraths.org.uk/) that aims to celebrate the scientific and technical achievements influenced by Malvern since 1942. They explained some of the background and theories associated with infrared to the audience which captured their interest and will also help with their GCSE studies. This was followed by discussions on STEM (Science, Technology, Engineering, and Mathematics) careers as these students will soon be making important decisions on what to do after GCSEs. The session finished with demonstrations and experiments using various infrared cameras to show infrared in a practical and fun way.
