Our worksheet was all about identifying what we ate and used at lunch time and whether it was Reusable, Recyclable, Compost, or Landfill. We had students list everything from the juice box to the plastic fork and try to come up with alternatives to the landfill items. After we finished we had students head up to the field for Decomposition Tag.
We had the whole class play this fun twist on Freeze Tag. A few students were the character of 'Death' who wore brown string to ID them. We had about 1/5th of the class act as decomposers who wore yellow string. All other students were plants or animals of their choosing. Death could freeze any of the plants or animals. If frozen, a decomposer could run around the frozen plant three times to unfreeze/decompose them. This game has no natural end, but we would stop every so often to have students change roles. This fun P.E. inspired class enforces the idea that the progression of life, death, and decomposition is a circle. We must have all of the elements for life to continue.
