In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants. Then, learners plan, design and build compost bins to further understand the process of decomposition and the products of decomposition that enrich soil. Learners put the bins to use for multiple weeks, recording the temperature and look of decomposing material and noting differences from week to week.
