8 Wendell s Waste Watch Results 1. Write your weekly totals in the spaces provided below. Total amount of compostable waste in week 1 = Total amount of compostable waste in week 2 = Total amount of compostable waste in week 3 = Total amount of compostable waste in week 4 = Total amount of compostable waste in week 5 = g g g g g 2. Calculate the weekly average of compost waste: 3. Multiply the average weekly total by the number of school weeks in a year (40). This will give you the amount of compostable waste in g the school can compost in one year: Average weekly total x 40 weeks = Top tip To calculate the weekly average, add all the weekly totals together and divide by the number of weeks. For example: week 1 + week 2 + week 3 + week 4 + week 5 4. Change your weights from grams to kilograms (kg). (There are 1,000 grams in a kilogram.) Total 5 = weekly average For example: 600 g = 6kg 8,500 g = 8.5kg Our school will compost approximately waste in one year. kilograms (kg) of compost PHOTOCOPIABLE 8 SEE PAGE 11
