Forensics Workshop
The annual forensics workshop took place on the 4th and 5th of November and were hosted by Scientific Sue from Science2life. 4E,4G,4H and 4J attended the workshop on Monday, the 4th. 4A,4B,4C and 4D attended the following day.
During the workshop, we learned about four areas of forensic science; these included paleontology (the study of fossils), blood analysis, fingerprint analysis and powder analysis. We worked in groups of four to carry out the tasks given to us.
In the paleontology section we made our own dinosaurs using pink foam and a small dinosaur toy to create a mold. Afterwards, we were able to create a foam mould for the next group to use the following day.
In the blood analysis section we tested three separate samples of blood to 'help catch a killer'. Using two bottles labeled sample A and sample B, we tested them with the blood samples and wrote down the results, which helped us find out the answers to the worksheet we were given. By adding either sample A or B into all of the types of blood, we were able to find out who the killer was, who was at the crime scene and the identity of the victim.
In the fingerprint analysis section we used a special fingerprint powder to clearly print our own fingerprints on a sheet of paper. Afterwards, all groups did an activity which involved us placing our fingers on each others' sheets and leaving a clear print. Each person in the group would then place their fingerprints on another members' page and so on. When we had all of the group's fingerprints successfully printed on the sheets, we’d then have to guess who’s fingerprint it was. It wasn't easy!
In the powder analysis section we had three different powders and three different solvents. We placed a small amount of each powder into a cup and added each of the different solvents to the solutes. We then observed the different chemical and physical changes that occurred in each experiment, and were able to identify each powder by their properties.
For the last fifteen minutes, Scientific Sue demonstrated how we can create chemical reactions using everyday items that can be found in our homes - chemicals like baking soda and washing up liquid, for example.
Overall, it was a very enjoyable day and gave me a huge insight into the work carried out by forensic scientists. I learned a lot of interesting new facts and I am now considering a career as a forensic scientist.
