The hypothesis is that biodegradable materials will break down faster than non-biodegradable materials.

You will separate into groups, fill bottles with soil, add materials, cover with soil, and sprinkle with water. You will also record initial observations and make guesses about which materials will break down first and last.

You will need six 2 liter plastic bottles with tops partially cut off, soil, water, scraps of vegetables, plastic, wood, metal, paper, styrofoam, labels for each category, and tape.

After completing the experiment, it was found that biodegradable materials broke down faster than non-biodegradable materials. This observation stands out because it shows that separating biodegradable materials to allow those to degrade, while minimizing non-biodegradable materials, will minimize the trash generated.

This science project is interesting and unique because it allows students to observe the breakdown of different materials in a controlled environment.

Experiment variations to consider include testing different types of biodegradable materials, such as food scraps, and testing different types of non-biodegradable materials, such as glass or rubber.
