In the process of discovering the extraordinary creature commonly known as a red wiggler worm—or as scientists would identify it, Eisenia fetida, fifth-grade students recycled their school lunch leftovers, made predictions about worm behavior in compost bins, discovered the process of decomposition, and valued the importance of organic farming methods. Students were able to develop science-process skills (e.g., developing a plan, measuring, constructing, using data, predicting, and communicating) and relate mathematical procedures in a significant way, all while their worms processed those lunchroom leftovers into organic plant food!
