Are worms important to plants?
Students will conduct an experiment in which they observe:
rate of decomposition of different organic and inorganic
effect that worms have on the rate of decomposition
of these materials and on soil quality
The initial set-up of the experiment will take approximately
three one-hour periods. Less time will be required if
worm "recycling centers" are constructed prior
to first class session. You may want to consider constructing
worm recycling centers outdoors to reduce clean-up. Worm
recycling centers should be observed once a week for one
month. Observations should be recorded. Each observation
recording session will take approximately twenty minutes.
