In KS2 this term, we are looking at super shapes in Science. To demonstrate how strong a curved shape can be, we wanted to see if we could stand on eggs without them breaking. To make the test fair, we all had bare feet and stood on 20 eggs, all turned with the narrow end facing down. Then we took turns to stand on the eggs for 5 seconds to see if they could hold our weight, which was the only variable we had. The weight varied from 21kg (lightest pupil) to 97kg (class teacher) and not a single egg broke.
This is because the unique shape of the egg allows the weight to be spread equally across it's structure. The more eggs there are, the more weight can be spread.
Next week, we are going to see if it's possible to make cube or pyramid shaped bubbles!
