By simply looking at each other the students can "guess" who would win an arm wrestle.
Simply looking gives them a little EVIDENCE so they are actually predicting NOT just guessing.
BUT just looking is not good enough for dependable predictions so this worksheet is used again but after the PUSH force of every student is measured first using an ERGOMETER (very large newtonmeter)
students can then match a small force against a very large one , can be fun, even more fun is when closely balanced forces DO generally take ages and it is the cheering of the rest that decides the winner
This sheet allows for some surprises as you will discover the small, weaker students actually beat some bigger students because of training, clubs, etc
