88 Miles per hour/teaching approach

88 Miles per hour Session 5 initially looks at time travel, however, that is not the real aim of this session. The overriding theme is that of models⁽ⁱ⁾ and the scientific method⁽ⁱ⁾. It aims to show students that it is OK to get a result that doesn't fit with what you expect, as it just means you need to change what you expect next time!
