Our first meeting in may was spent working on the BC CSI Challenge. As the girls arrived, they were asked to write the word 'Suspect' on two slips of paper, with their name on the back for an activity later in the evening.
To take advantage of the good weather, we went outside to play games at the beginning of the meeting. The first game was Crabs, Crows and Cranes. In this game, the girls are divided into two groups, one team is the crows and the other is the cranes. The teams line up facing each other and the game leader calls out 'Crows', 'Cranes' or 'Crabs'. On 'Crows', the Crow team chases the Crane team, on 'Cranes', the Crane team chases the Crow team, and on 'Crabs', everyone stays still. Anyone tagged, or caught moving on 'Crabs', joins the other team.
Our second game was a version of How Good a Witness Are You?. Girls lined up in pairs, facing each other. On a signal, the girls turned their backs and each girl changed three things about her appearance. When everyone was ready, the girls faced each other and tried to figure out what their partner had changed. We did this a few times as it was popular with the girls.
Going back inside, we started with Fingerprints. Each girl used talcum powder to put her thumbprint on a piece of black card and then covered it with clear tape. Using pictures, they identified if their print had loops, arches or whorls.
Next, we used the slips of paper the girls wrote on when the arrived for Handwriting Analysis. Each girl was given one two slips of paper and had to find the people who held the matching slips. This was more difficult than the girls thought it would be as many people's handwriting looked very similar.
Our final activity of the evening was to extract DNA from strawberries. The instructions for this activity can be found in the activity pack for this challenge. This is a really neat activity to do and the results are tangible.
