A Sample Dichotomous Key

1. wings covered by an exoskeleton . . . . . . go to step 2
1. wings not covered by an exoskeleton. . . . go to step 3

2 body has a round shape.
2 body has an elongated shape.

3.wings point out from the side of the body . . dragonfly
3 wings point to the posterior of the body.. . . . Housefly

Note: There should be one less step than the total number of
organisms to be identified in your dichotomous key.
. . . . . . . ladybug
. . . . .grasshopper
Sample Stations –
Population Density





Measure sample area
Determine population density for symbols
