The hypothesis is that reducing, reusing, recycling, and recovering our waste can help keep our planet healthy.

You will learn about landfills, composting, and incineration, and how they affect the environment. You will also play a game and learn songs to help you remember the importance of reducing, reusing, recycling, and recovering our waste.

You will need two 2 liter plastic pop bottles, netting or mesh fabric, rubber band, classroom storage containers, plastic bags, soil, vegetable or fruit scraps, grass, newspaper, plastic and other garbage, aluminum cans, glass bottles, paper napkins, and fruit peel.

We can make a difference in the environment by reducing, reusing, recycling, and recovering our waste. We can also learn about landfills, composting, and incineration to help us understand how our waste affects the environment.

This science project is interesting and unique because it combines learning about the environment with fun activities like playing a game and learning songs.

Experiment variations to consider include composting different types of waste and comparing the results, or researching different types of incineration and their effects on the environment.
