Hi Courtney, interesting question! When a scientist studies the material used in food packaging, they need a better understanding of decomposition. Generally inorganic materials are unsafe to eat, and take years to decompose.

If I may suggest what to do for an experiment. The purpose could be to gain a better understanding of the conditions leading to decomposition of organic foods. The microorganisms that break down organic waste need a particular environment to thrive. Like all known living creatures, they need water, oxygen and the right temperature and acidity to thrive. Your hypothesis could be that the microorganisms in soil will completely decompose organic food faster with regular watering, turning over the soil and access to oxygen. For example, you might have your independent variable (s) be the amount of water added, the access to sunlight, the access to oxygen, the pH of the organic food. For instance, compare a lemon's to a banana's decomposition under different soil conditions.

Try closing some jars of soil with a lid, to create an oxygen deprived environment. Or poke holes in the top! Get creative, and you will have a great investigation! Good luck!

Note from ScienceLine Moderator:
The scientist answering to this question would like to make it clear that the experiment with inorganic materials would take years to be fruitful, so it is more convenient for you Courtney to learn from the experiment that our scientist is suggesting to you.
