On the first day of your visit to Hard Bargain Farm, you weighed the lunch trash from your class. Now, that information is posted here on our web site on the Lunch Trash Data Sheet along with information from other fifth grade classes. After seeing your trash data and how it stacks up against other classes that came to the farm, find out how it all adds up! An ounce or two of trash per person may not seem like very much, but that trash piles up in our landfills. Use the following calculations to find out how.
  
|
|
| 1. Using the information from the Lunch Trash Data table (Average trash weight/person in ounces), figure out how much trash you would produce packing your lunch the same way you did for your trip, for the entire school year (186 days). |
|
________ oz. Average trash weight/person |
X |
186 days (days/school yr.) |
= |
________ oz. Average trash weight/person/school yr. |
| 2. Convert your answer for #1 into pounds. |
|
_______ oz. Average trash weight/person/school yr. |
`/. |
16 oz. per lb. |
= |
________ lbs. Average trash weight/person/school yr. |
| 3. If you packed your lunch every day of school, 186 days of school per year, for 12 years, the entire time you attend school, how much trash would you have accumulated in pounds? |
|
_______ lbs. Average trash weight/person/school yr. |
X |
12 years of school |
= |
________lbs. Average trash weight/person/12 yrs. |
| 4. How much trash would your whole class produce in 12 years of school? |
