Forensic footprints Activity Card Things have been going missing from Class 5 at StarTown Primary. Last week, Gem left her colouring pencils out and after lunch they were gone. Yesterday, Cosmic left his jumper in the classroom and this morning it wasn’t there anymore. A mysterious footprint has been left on the classroom floor and Gem thinks that they can use forensics to figure out who is responsible, just like a real detective. She thinks they can use the footprints to work out how tall they are. 28 cm Height of suspects: Mrs Teachem: 153cm Mr CleanUp: 187cm Nurse: 160cm Gardener: 198cm Your challenge Can you help Class 5 figure out who has been moving their things? Is there a relationship between foot size and height in adults? Discuss What do you think the relationship will be between foot size and height? How will you calculate the relationship between foot size and height?
Getting started You’ll need to find some adults who don’t mind having their feet and height measured. You will need to measure the length of their foot from the heel to the tip of the big toe. Test your ideas How will you record your findings? Could you make a graph to show your results? How will you use your findings to calculate the relationship between foot size and height? Share your ideas Foot Size Height Tell the rest of the group about your results. Do you think your experiment was fair? Could you do anything to improve it? Who do you think the culprit was?
