Height vs arm length- are they related?

Here’s a great little investigation into whether a person’s height and arm length are related. The pupils get a copy of this worksheet and have to use a metre stick to measure the height and arm length of ten of their class colleagues to the nearest cm. After recording their results in a table they draw a scatter graph and answer the questions at the bottom of the worksheet to think about whether there is a correlation. They could be encouraged to share their findings and justification with the class in a discussion in the plenary.

You’ll need metre rulers or tape measures and graph paper for this lesson in addition to the worksheets. Enjoy!
