Worm Wranglers
Third graders set up and maintain a worm composter. They monitor the waste from their lunches, prepare the menu for the worms, and determine how the keep the worms alive.
Curated OER
Soil Preparation for Autumn and Winter
Students determine how and why soil needs to be prepared for the fall and winter seasons. In this agriculture lesson, students determine how to use gardening tools safely. They show how to work with compost material and fertilizer to...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Trash Disposal Choices
Students determine the differences between reusable, compostable and recyclable trash.
