Forensic Science with Dr Kenworthy

In week 3 of term 2, there was a ‘staged’ robbery at Waikanae School. The school’s safe was stolen from the Library.

Our class was divided up into Forensic Investigation Teams who collected evidence from the crime scene before taking it back to our  'laboratory' to analyse it and draw conclusions. As the days past, more information was revealed and ‘Police reports’ on the suspects were provided.

On the final day, each team presented their evidence and declared WHODUNNIT!

Here is my Daily Diary.

Day 1

Firstly we were put into soco groups to work in  for the week . Dr Kenworthy gave us our tool box full of forensic equipment. soon after that we were given beakers to put water in , once we had done that we were given a piece of chromatography paper, some die and three capillary tubes. Next we put three drops of each color on the paper, before putting the paper in the beaker to watch the die expand  

After a quick break we got started on fingerprinting

We had to fill out a form and put down our fingerprints, most of us had black fingers.

THe water rises because of the capillary action.

Day 2

The first thing we did was lifting fingerprints, we had to grease our fingers and then press them down

onto the tile. After that we got the brush and the graphite  and brushed the tile to uncover our result

, we then had to put the sellotape on the fingerprint and gently pull it off.

After about five minutes we went off to the library

to investigate, we needed to lift the fingerprints and collect the evidence.

When we came back we matched the fingerprints and Dr kenworthy told us some gross stories.

Day 3

Firstly we went over to the crime scene by the staff room and collected the material and brought it back.

Next we got a little tube and  put a little bit of water with the material and shook it before putting little drops on the chromatography paper with the dyes before  matching it up with the other dyes, we found out that it was from an all blacks t-shirt.For the next twenty minutes we tried to figure  out and decide who done it. We thought it was big bert [ Albert Allen ]
