Does a school classroom hold an appeal for you or fill you full of horror? Alex and rookies Joseph and Ophelia find out exactly what it takes to make it in the world of teaching. Science expert Greg Foot puts them through their paces, testing their ability to hold people's attention by trying out some science tricks on the general public. They take a class for a lesson with a difference, teaching literacy and numeracy not in a classroom, but in the woods near their school. Finally, they are left alone with a class as they attempt to teach them a song to perform at the school assembly. This is the nitty gritty of teaching, as Joseph and Ophelia must keep control of the group with no outside help.
