Year 3 have been looking at skeletons and bones in science and this week investigated whether a longer femur length (thigh bone) meant that you could jump further. They had to think about making our test fair, jumping in the same way, starting behind the line and measuring from the same place on everyone's feet. They found that the length of the femur didn't affect the length of the jump, and some of the children with the shortest leg measurements actually had the longest jumps.
