Notes about using video
Video is in 5 sections broken up to allow you to discuss variables and how to make investigation a fair test. It is very difficult to produce a definitive video to do this as the direction for setting up any investigation should be driven by the thoughts of the student, so you can of course do this your own way and don't have to use the videos. The key point of this discussion is about what is needed for a fair test. These points will invariably be made differently with each class.
