Our STEM week theme is Nottingham Invents.
As a class we have researched MRI machines. This is what we have found out:
In 1977, the first idea for MRI machines came about from Sir Peter Mansfield, who worked at the University of Nottingham. He won a Nobel prize in 2003 for his work, and a tram was named after him in 2015. MRI machines transformed medical science.
The machine scans all your body – including the squishy parts. It uses magnets, coils and radio waves to take a picture of your insides. A scan lasts 15-20 minutes, and you can’t wear any metal inside the machine.
It is noisy in the machine, but they warn you before the louder sounds start. It is painless, and you are given noise defending headphones (ear protectors). A moving table takes the patient into the hollow tube of the machine.
This local invention is now used around the globe.
In class we have been learning about sound.
We invited our adults into school, and showed them 3 different experiments. We investigated how size affected pitch.
