Year 5 Forensic Science Workshop

For Science Week, Year 5 have had a Forensic Science workshop! Our leader, who was hosting the workshop, was called James. It was all about investing a crime scene and determining which of the suspects had stolen the 500 diamonds from our precious school safe.

We learnt how to find evidence including fingerprints but also, we needed to know how to not contaminate the clues or  the crime scene. Everyone has a slightly different fingerprint. Even identical twins have different fingerprints. We were also taught that DNA is a good clue to find but it can’t always help you find the suspect.  The reason why is because if people are identical twins, they both will have the same kind of DNA. DNA stands for DEOXYRIBONUCLEIACID .

After all of that talking, we started searching for some evidence and there were all kinds. Some stuff didn’t give many clues like glasses, you never know if that person really wears glasses or if they belonged to someone else. We also found footprints and coins so they did leave some kind of currency.

Now let’s talk about the investigation. We split up into groups and we saw a folder that had a card with a name inside. We also found a fingerprint that was a loop shape so it had to be someone that also had a loop fingerprint. We also found a footprint and after all of that we mixed all of the clues together and we found out that the thief was named Mindy Morris. She also had an identical twin that had glasses – but a different fingerprint.

Year 5 Science Week Tower Experiment

For Science Week Year 5 have been working on building a tower stable enough to hold an egg. We could only use masking tape and newspaper, an egg and a plastic bowl to hold it inside. It had to be tall and secure , for the egg had to stay off the ground. As well as that, we had to be able to carry our towers to the testing table. For this challenge, we only had an hour to create our towers. When we tested our towers, they had to be able to hold the egg off the ground and stay idle for 15 seconds.

Our results were different than expected, especially as some towers were more successful than others. Most towers were unsuccessful due to the fact that they weren’t balanced.

Here are some tips that we found useful:

  • Always have a strong, firm base.
  • Use pyramid like shapes for a solid base.
  • Try and use beams in order to keep your tower tall and in shape.

It was an EGGTASTIC time!!
