Science savvy youngsters tackled a CSI-style scenario staged at Blackheath High School’s Senior School.
The Junior School pupils were briefed about a serious robbery and were sent to find clues and reach conclusions from sessions in chemistry, biology and physics.
Teachers helped the girls, aged nine and 10, use microscopes to analyse fibre, materials and powders and they were shown how to harness UV light.
Students also picked up tips on analysing footprints and assessing the reliability of eyewitness statements.
They then compared evidence and feedback and discussed findings.
The event aimed to raise awareness of roles in science, technology, engineering and maths (Stem).
