In this activity, students use observation to explore earthworm anatomy and the nature of science.
By the end of this activity, students should be able to:
- identify various physical characteristics (such as segments, clitellum)
- describe how an earthworm uses its circular and longitudinal muscles to move
- discuss how their observations and experiences in the classroom mirror those of real scientists.

- hints for finding, housing and handling earthworms.
Nature of science
Science is based on observations of the world around us. Scientists use both their senses and instruments to make systematic observations. Scientific knowledge is modified as new evidence comes to light.
