This resource introduces the formulae for the surface areas of cylinders, cones and spheres. Students are asked to use these to model parts of the body and calculate an estimate of their own body's surface area. Two formulae used in medicine for body surface area are also given so that comparisons can be made.
When calculating an estimate for their own body surface area students need to make decisions about measurements, estimates and calculations. They are also asked to substitute height and weight data into formulae. The Pearson product-moment correlation coefficient can be used to explore correlation..
The resource includes a student handout, PowerPoint and teacher notes including suggestions for different approaches and possible extension activities.
