Section 2: When Snack Time is Over…

httpsswilson37-wordpress-comtaglandfill

When you finish your snack, what do you do with the leftover packaging? More than likely, you either throw it in a trash can or put it in the recycling bin. You may think that this is the end for the snack packaging, but it is actually the beginning of a long disposal process.

This lesson examines the four possible options for disposal: reduce-reuse-recycle, composting, combustion, and landfills. It also looks at each type of snack packaging material to see what happens after the consumer disposes of it.

In doing so, the lesson demonstrates the environmental impact of each of these methods of disposal and materials. To do our best and help our environment, we have to understand the effects of the choices we make.

Calculate the amount of food packaging waste your students generate in a typical school day. Using this number, calculate how much waste they generate in a week, a month, and a year. Use these numbers to consider how long it takes for your class to generate a ton of trash and estimate the volume of waste produced. Complete a series of questions based on these findings.
