The students of Year 10 (classe de 3ème) worked on the systems of units. They compared the  US system and  the metric system. They discovered that some accidents happened due to a confusion between the two systems such as the story of Gimli Glider in 1983, when the engines of plane supposed to connect Montreal to Edmonton ran out of kerosene during the flight.

The students had to write a scenario to show a misunderstanding with units and perform it.
