This is a spreadsheet which is used as a set of lessons based on pupils exercising and recording the amount of calories they burn off in a set time. The pupils can work as individuals or in teams, they exercise and collate the amount of calories they use during their activities. This is then compared to food produces to create a comparison of their effort against calorific intake. The team and class averages are recorded and this can be used as a target for the following weeks' lessons. "Exercise , calories, diet, comparison of exercise and calories".
