They see what we call garbage turned into something useful. Then they see that it helps the plants in the greenhouse grow. This year, Joplin students managed six worm compost bins in five classrooms. When the worms have finished recycling food wastes, students spread the new compost over plants in the school greenhouse. The best thing about this project is they get the chance to see nature in action.
Students also learn about worm biology, climate, soil composition, and scientific classification.
They practice their math skills by measuring and weighing food scraps, figuring ratios and averages, and graphing information about the worms. Master Gardener volunteers helped children in worm composting projects at 11 public libraries in Chicago. CES now offered a worm composting curriculum to city and suburban teachers. Teachers can attend a workshop to learn how to set up a classroom worm bin and how to integrate worm composting into other curricula. For a fee, teachers receive worms, worm bins, and teaching materials.
