Who stole my biscuits?

Saturn’s classroom became a crime scene this afternoon when somebody stole Mr P’s secret stash of biscuits!

Luckily, the class were on hand to use their detective skills to crack the case. Using chromatography, the children were able to identify which pens had been used to write the notes left behind by the thief. By dipping paper and ink into water, we watched as the ink dyes separated into different colours – allowing us to match up the pen to that which had been used.

Oh, and it was Jacob ‘wot dunnit’…
