EXPERIMENT: BIODEGRADABILITY

EXPERIMENT: BIODEGRADABILITY Do you have chores around the house? Is one of them taking out the trash? What do you think happens to the garbage you leave on the curb for the trash company? About 55% of garbage in the United States is dumped in landfills. Unfortunately, most trash will stay in a landfill for hundreds of years. Many products used today are disposable, meaning they are used only a few times before being thrown away. Most disposable products are made of materials that do not decompose or break down easily. These products are not biodegradable. For this experiment, you will determine the biodegradability of different materials. Materials shovel or trowel compost bin (can be purchased from a local garden or hardware store) dirt twigs and branches grass clippings or leaves food garbage (such as banana peels and apple cores) plastic cup newspaper aluminum foil tissues paper towels tin can Directions Choose a flat, dry area for your compost pile. Add two inches of wet dirt to the bottom of the compost bin. Lay a four- to six-inch layer of twigs and branches on top of the wet dirt to help air circulation. Add grass clippings, leaves, food garbage, a plastic cup, a newspaper, aluminum foil, tissues, paper towels, and a tin can to the compost bin. Carefully mix the contents of the bin with the shovel or trowel. Be careful not to disturb the layer of twigs at the bottom. Observe the compost pile for two weeks. Keep track of materials that were broken down by bacteria and those that were not. Answer the following questions in a 130 word essay: Which materials were biodegradable? Which materials were not biodegradable? Why do you think some materials decomposed but others did not?
