Today, Year 4 carried out a science investigation to find out who had stolen and scoffed our biscuits! 🍪🔍
The culprit had left a message written in black ink, so we used chromatography to test the ink from the four suspects’ pens. Using filter paper and water, we separated the colours in each ink and compared the patterns.
After careful investigation, we discovered that the biscuit thief was… Mr Moon! 😲
