Many members of the Corps of Discovery learned to be scientists
on the expedition. For instance, they were biologists noting new
species of plants and animals. And they were astronomers using
the stars to guide their path.
In the following activity
you are a botanist. You must explore the area and identify plants
the way the Corps did.

|You'll describe the features of a pressed
out the botany
worksheet. Use scientific vocabulary to write a description
of a pressed plant based on the following:
- Arrangement of
the leaves-alternate, opposite, or whorled along the stem.
- Shape of the leaves-entire
or compound; lobed (pinnately or palmately), toothed, dissected,
heart-shaped, ovate, lanceolate, or linear.
- Arrangement of
the flowers-single, umbel, spike, sessile, cyme, or head.
- Shape of the flowers-regular,
irregular, or composite.
- Color of the flowers.

Pretend you discovered
this "new" plant. Think of a name and share it with
the group. Write a folktale about your plant. Share it with the
dichotomous key to look up the actual name of the plant. How close
was your name to the one that botanists gave the plant?
