Sam is a substitute High School teacher that has just been thrown in the deep end. One of the permanent teachers has had a nervous breakdown and Sam has been asked to step in to teach a Grade 9 Natural Sciences class at the last minute.
With hardly any time at all to prepare, Sam decides to teach them about something novel and current like the recent volcanic eruption on the Indonesian island of Bali. Sam thinks this is an exciting topic that should hopefully, engage a group of 14-year-olds with a notoriously short attention span. This is the “hashtag” generation and they need constant stimulation to keep engaged.
