EXPERIMENT WITH COMPOSTING AND LEARN ABOUT FOOD WASTE
June 3, 2019
Home / Science Center: Home Experiments For Kids / Experiment with Composting and Learn About Food Waste
Parental Note: This experiment is geared toward ages 8 and up to be completed independently with some help from an adult. The project may require some adult support when cutting materials.
Note: This experiment will take roughly three weeks to complete. Prior to the experiment (1-2 days), collect organic food matter (orange peels, excess fruit, egg shells, etc.). Place the materials in a plastic bag and then in the refrigerator to be used for the experiment.
Experiment Overview:
Take a minute to think about the food you throw away each day. The amount of food waste that ends up in the trash after breakfast, lunch, dinner and snack time. Now, take that idea and think about how much food waste occurs in the United States each day! On average, Americans waste about a pound of food each day per person. That is one pound of food waste per person per day. With roughly 300 million people living in the United States, the amount of food wasted each day is huge.
1 (lb) of food multiplied by the U.S population 326,766,748 = A TON OF WASTE (163,383 tons to be exact)
The good thing about this food waste problem is that there is a rather simple solution called composting. Composting is the natural process of decomposition/recycling organic materials into rich soil. These organic scraps (vegetable peels, fruit waste, plant clippings, and grass cuttings) turn into a material called compost. The compost is rich in nutrients and wonderful for house plants, gardens, and other outdoor plants. There are also many other benefits to composting:
Reducing the waste in landfills, which directly links to the idea of “reduce, reuse, and recycle.”
Reduction of methane emissions from landfills which lowers our carbon footprint.
Reduces the need for commercial soil fertilizers (which also helps with water pollution).
Helps control soil erosion.
Composting happens naturally in forests when leaves fall and form a mulch-like layer that protects the soil. The leaves decay and decompose over time to create nutrients that feed the forest plants. This natural process can be replicated through the use of composting bins that can be placed in your own backyard. In this experiment, we are going to create a small composting bottle to visually show the composting process and better show how composting can reduce food waste and help the environment.
Experiment Materials:
Clear plastic bottle (pop bottle)
1 cup of fruit, vegetables, and other organic food waste from the kitchen
1 cup of leaves or grass clippings
1 cup of shredded paper
5 cups of potting soil
1 or 2 cups of water
Tape
Scissors or sharp object
Permanent marker
3 paper plates
1 large bowl
1 measuring cup
1 spoon or cup
