Second grade classes from Avon East Elementary School created composts to develop a better understanding of chemical change, decomposition and the difference between organic and inorganic objects. The students chose several items to place in the compost piles making predictions to whether they would decompose or remain in the same state. Students from Avon, Ohio and Miami Florida discussed the items and their predictions.
Classes started with large freezer bags half filled with dirt. After adding organic and inorganic objects, the groups added water and worms for the feeding to begin. The worms will enjoy their new dinner for a couple weeks as they are only disturbed for class observations. The students from both schools are looking forward to comparing their results.
