Computer Science KS3 & 4 / GCSE: Problem Solved - Lost Dogs

BBC Radio 1 presenter Dev visits Battersea Dogs and Cats Home to look at ways computer science can be used to help reunite lost dogs with their owners.

He explains and evaluates the current system of RFID chipping. Using computational thinking he proposes both a complementary and an alternative approach to the problem of lost pets.

Animation shows how abstraction can model selected aspects of the external world in a program.

Teacher Notes

Pupils could investigate the potential uses of sensor technologies, and mapping to solve the problem of lost pets. Are there ways you could use computational thinking to improve the current system? Computational thinking is about exploring all of the different ways it can be done.

In class, pupils could use computational thinking to make a tried and tested method – like lost dog posters – as effective as possible. How can you optimize the poster location? What factors would you have to take into consideration: the size of the dog, its stamina, the length of time it has been missing? Familiar walks and places? When will it be hungry?
