Observing earthworms
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.
Physical adaptations for life underground
Although earthworms are classified as animals, their bodies are quite different to animals that live above the ground. This video highlights some of the interesting physical characteristics common to earthworms.
Point of interest: Visit the two interactives that show the inside and outside of earthworms to learn more about their physical characteristics.

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.
