Crime Scene Investigators

We have been looking at the different clues that are sometimes left behind at a crime scene. We started with finger prints and found out if we had whorl prints or arch or loops. Then we pressed our finger onto a stamp pad to check. After that we pressed our thumbs onto a hard surface. Using talcum powder and sellotape we tried to find a good print. It wasn't easy but magnifying glasses certainly helped us see our results.
