1. Students divide into groups of 4 or 5.
2. Students will divide their leaf packs inside the dish tubs.
3.
One group at a time washes their leaves of material and insects into
the fine mesh sieve. (If not enough sinks are available, the children
can sort through the leaves to find the bugs without washing them)out.
4. Students will transfer this material and all creatures into the shallow white plastic trays and add water.
5. Using the hand lenses and discovery scopes they observe the different creatures obtained from the leaf pack.
6. Each group preserves their macroinvertebrates in the large plastic jars with alcohol.
7. Groups talk together to answer the following questions:
a. Based on your observations, what do you think the creatures are that you obtained from your leaf pack
b. What do you know about animals that come from streams?
c. What do you know about plants that live in streams?
d. Why do you think these creatures are living in the leaf packs?
e. What more would you like to know about leaf packs, the animals you found, and the streams they came from?
8. One person from each group will be chosen as a recorder. That person will record the answers from the group.
9. One or more persons will act as reporters from each group to report their findings to the class.
10. We will find the location of any of the streams from which leaf packs were collected.
11. Charts from each group will be saved for future use.
