Interactive and good lesson on 'control'. It is important that teachers create extraneous variables whilst students are taking part in small experiment. This includes ringing of a phone, talking to students, tapping a pen, opening and closing door, flicking through powerpoint slides quicker than others. The students enjoyed the lesson.
