Maths STEM club attendees got a feel for keyhole surgery this week, using clay, string and straws to mock-up a knee joint. The pupils reattached the ‘ligaments’ using a pair of tweezers in each hand whilst viewing their progress on a Chromebook connected to a visualiser. The exercise gave an insight into the levels of skill, concentration and patience needed to become a surgeon. We discussed the magnification needed to ensure the surgeon has a clear picture and how many times smaller the cutting tools needed to be, compared to an average pair of classroom scissors.
