Question from Sydney: Dear Super Science fair projects.com, I am a ninth grade girl and I need a science fair project idea. I love the environment, and I wanted to do something to show how plastic bags effect the environment, but I cannot think of any ways to test that. We are using the scientific method for out projects, and I was wondering if you could help me with an idea ASAP! Thanks so much 🙂
Answer: How about burying some plastic bags in a hole in your backyard for a month and in another hole bury 100% paper bags for the same amount of time? Mark your "graves" and dig up the bags one month later. Which ones decomposed?
You can probably get some friends to do the same thing and see their results. The more people who participate the more your statistics will show if either of these materials re polluting our ground and / or ground water.
Perhaps your classmates can do the same in a small section of the school garden.
If you have access to a science lab, perhaps at the high school or college in your town, for a more advanced project you can take samples of the soil that are in each of the graves and see if the material left toxic residue in the soil.
To do this you will need to use sterilized plastic gloves, sterilized petri dishes or test tubes so that the soil does not get contaminated with your germs or in the holding containers.
