We investigated the weight of food wasted per day in Hot Lunch because we wanted to show people how much precious food, which people in poor countries need so badly, is wasted by the middle school students. To do this we weighed the buckets of wasted food every day for one week.
To work out the weight of wasted food, we measured the buckets in the lunchroom without food (306g). Then we measured the buckets with food every day after Hot Lunch, added their weights together and subtracted the weight of the buckets (918 as there are three buckets). Ex. 1,600g + 1,560g + 3,900g = 7,060g - 918g = 6,142g
