How to Make a Compost Sandwich

The activity helps students remember what to put in the compost bin.

Begin with an accordion book:

1. Fold the paper in half.

2. Take the top layer of paper, flip the edge back to meet the fold, and crease.

3. Turn the paper over, flip the edge of the paper back to meet the fold, and crease.

Decorate the outside like slices of bread.

Fill the inside of the accordion book with brown stuff, green stuff, air, and water (oops- this book has soil instead of air).
