Keeping Baby Warm

This Cre8ate maths activity investigates the ratio of surface area to volume in adults and babies and explains why we keep babies wrapped up in winter.

To calculate surface area and volume students make scale models of a baby and an adult. The models may be simple in nature, such as a single cuboid, or a more complex model involving a variety of cuboids, cylinders or even spheres. Depending on the approach chosen, there will be the opportunity for substituting in formulae either algebraically or in a spreadsheet.
