"Jon\r\nChase describes how different elements absorb and emit light of specific\r\nwavelengths or colours. He explains how this can be used to identify which\r\nelements are present in distant stars by analyzing the spectrum of radiation\r\ncoming from these stars. Teacher notes: You could discuss how white light can\r\nbe split into its spectrum and students could make their own CD spectrometer. Students could investigate the flame colours produced by different elements. A\r\npiece of metal could be heated to show how the colour changes with increasing\r\ntemperature. Relate this to the colours of different stars.\r\n"
