Composting & Worms Unit Study

Composting is fun, easy, and great for the environment, but it is also an excellent science experiment to teach kids more about biology, life cycles, recycling, and conservation.

Composting is a natural process of decomposition that recycles organic material. Nature recycles leaves and plants into nutrients that feed forest plants. You can set up a composting bin at home to recycle leaves and plants to use in our gardens to grow fresh fruits and vegetables.

Build a Micro Composting Bin

What you Need:

  • Transparent 2-Liter Soda Bottle
  • Scissors
  • Food & Lawn Scraps
  • Spray bottle with Water
  • Gardening Soil


Rinse your soda bottle and remove the label. Cut the top off the bottle.

Fill the bottom of the soda bottle with a handful of gardening soil.

Then add some of the lawn scraps, followed by a few food scraps.

Repeat this process until the bottle is full, finishing with a layer of soil.

Once your bottle is full, spray the bottle with water. Do not soak it; it should only be damp.

Place your composter in a sunny spot. Spray your composter when it becomes dry to maintain moisture.

Watch and wait as your food and lawn scraps decompose and turn to soil.  The whole process will take about eight or nine weeks.

Use a draw and write notebooking page to record the process with photos or a drawing each week.
