5 Blue turned into investigators today! Poor Susan was murdered and 5 Blue had to find out who had done it! They used Chromatography, a scientific technique used by CSI technicians. It is used to separate the components, parts, of a mixture. The unknown or suspicious mixture is separated by letting it move over a surface.
5 Blue took to testing this paper Chromatography. The 4 suspects had a favourite black pen, at the scene the pen was in water and didn’t separate. 5 Blue had to test these pens, by marking the paper towel, dipping it in water and then waiting to see if it separated or not.
Who did you suspect?
Who did the crime? What evidence did you find?
