For one week, keep a record of how many times you use devices powered by batteries. Record what kind of device you used and the number and type of batteries it contained. Your teacher will provide you with various batteries and a balance. Record the mass of each type of battery you used during the week. Assuming that your battery usage is typical of everyone in the country, estimate the mass of waste material produced by battery usage in one year. Write a short report offering ways to reduce the amount of waste.
