I bought the single-use kit to use with my 30 student classroom. I just couldn't afford the classroom version.
Luckily, it was easy to extend the single use kit to give all 30 students hands-on activity. For starters, we copied the CDs to use in the computer lab. Tom and crimescene give you permission to do that! We then copied the printed materials so everyone had a handbook.
Instead of using the single item of fingerprint evidence that crimescene sent (a fingerprint on glass), I created 30 of my own items of print evidence and altered the handout ( I had to replace the comparision print with my own so they'd match.) We just shared the brush and powder.
I could have ordered more hemestix for blood tests, but opted to just do one as a whole class demonstration.
For $60 I got an awful lot of use out of this kit and will reuse again.
A NOTE FROM CRIMSCENE: We condone copying the disks and handouts for classroom use. We are also constantly impressed by the resourcefulness of teachers.
