A full lesson based on the new AQA (P7.5) SOW but can be used for others. The lesson covers activity, count rate and the Geiger counter. Students are then taught how to calculate half life from a graph using examples. A worksheet is then completed (taken from another TES author). Students then complete a simple practical to model half life; they roll small cubes (or dice) and take the cubes that land silver side up (or on the number 1) out of play. Students plot a graph and answer questions relating to the practical. There is then a final grid challenge that students can use to assess their progress against the learning objectives. All answers are incorporated into the sides, timers are used to promote pace. Video used and radiation sickness discussed in order to incite interest.
