A one lesson hour long CSI investigation

this has a suggested organisation cards using four teams, i have made a worksheet with suspects and the victim, the attacker is always the cinema mangaer, i make blood splatter by drawing the splatter with a uv pen and then getting people to scan for it with uv you need slime made from fybogel (if you put highlighter ink fluid in the water it glows with uv) and pva slime (recipes from about.com chemistry) and i used four weapons (a book, a glass ashtray, a broom handle and a wooden rolling pin) there are also deduction cards so teams can find out who did it at the end
