A 60 minute lesson in which students will identify the external features of an earthworm.
This lesson contains a link to an external video. Please watch the video prior to presenting this lesson to ensure that the content is appropriate for your students.
Students watch and listen to the Worms For Kids video on YouTube. At the end of the video, ask the students:
What do earthworms eat?
Why do earthworms live under the soil?
How do earthworms make tunnels?
How do earthworms feel the light?
On the board, draw a basic outline of an earthworm. Explain to the students that earthworms have tube-shaped bodies and do not have arms and legs. Add segments and small bristles to the outline (8 on one segment). Explain to the students that an earthworm uses its segments to shorten and lengthen its body. It uses its bristles to help it move through the soil.
Use a slinky spring to demonstrate how an earthworm moves. Show how earthworms have circular muscles around each segment, moving along by stretching and contracting and by getting longer and shorter.
Provide the students with their own copy of the worksheet. (Note: There are two versions of the worksheet; one of which is a more scaffolded version.) Ask the students to draw and label the features of an earthworm using the key vocabulary provided. Monitor and support the students as they complete this task.
Watch and sing along to the Herman the Worm song on YouTube. After watching, encourage the students to suggest which external features the cartoon worm (Herman) is missing, and how he might be drawn more accurately.
Encourage more capable students to add additional details to their earthworm drawings.
Support less confident students by providing them with a scaffolded version of the worksheet (available within the resource).
