Year 5 - CSI18 March 2020 (by Jane Sparkes (admin)) |
Monday 9th March
Miss Wetton's Year 5 class have been CSI investigators!
The children used "chromatography" to determine which pen had been used to write a note. This involved testing the pens, using filter paper and then allowing water to soak through the ink, creating patterns and separating the colours. Each brand of pen had a slightly different pattern and colour combination, allowing the children to find the culprit!
