Our Year 10 iStem class participated in a forensics workshop where we investigated a mock murder investigation. We participated in many engaging activities such as matching hairs and fibres using a microscope, deciphering the missing words of a document using an oblique light and matching the suspect’s fingerprints to those found at the crime scene.
We also extracted the DNA of strawberries by mashing a strawberry in a bag and then combining it with hot salty water, detergent and methylated spirits. After stirring the mixture with a skewer, we were able to collect the strawberry’s DNA. This was an interesting and rewarding experience which gave us an insight as to what work in the field of forensics could include.

On Thursday the 21st of June, the Year 10 ISTEM class were able to participate in a Forensic workshop consisting of fun activities and problem-solving skills. The main activity we completed was to solve and investigate a crime scene. To find our suspect, we went through a series of tests that involved identifying footprints, testing DNA and pH levels, fingerprinting, hair and fibre testing, comparisons between different teeth shapes, and looking closely at the imprint of writing on paper through an oblique light. From these procedures, we were able to determine the suspect who was most closely related to the crime. The workshop guided our understanding of what forensic science involves and taught us new and interesting skills.
