3. Why did you count your stride over a 2,000cm length rather than make only one stride measurement?
4. A series of footprints were found in the mud outside school. Based upon their measurements (see below),
calculate the leg length and height of the person. Who do you think the footprint belongs to? Write a paragraph
describing what the person was doing. Measurements: Foot Length = 29 cm; Stride Length = 160 cm
SUGGESTIONS FOR FURTHER STUDY
1. Since criminals seldom go barefooted in your garden, see if you can figure out a way to estimate the height of
a person walking through your garden with shoes on.
2. If you found some ancient footprints of some early humans that had been made in damp sand, then hardened
and covered with sediments, how would you estimate the heights of those people? Would their footprints be
the same size as their feet? Find out by walking on damp sand, and measuring your feet AND your footprints.
Any difference? Get those measurements from as many people as you can, and determine the average
difference between foot and footprint measurements.
3. How would you like to walk in the footprints of a 3.4 million year old person? If this sounds interesting, ask
your teacher to do the Footsteps in Time lesson in your class.
