Learning task 4

Spider webs

Ask students:

  1. How would you begin to construct a web if you were a spider? Does the spider construct it randomly or is there a pattern? Allow students time to consider their answers and then share ideas.
  2. How do you think, for example, the orb spider spin a web?

(The spider initially sets up a triangular shape from its web. The outer spiral forms the main part of the snare. It is spun from the outer edge toward the centre with sticky silk.)
Close read for information/explanation:

Students orally identify and name three different types of webs: orb, triangle, and tangle.

Students work with a partner and sequence the steps for the making of an orb web.
Shared writing with a partner. Plan and write a draft explanation for either how an orb web is made or why a spider does not get stuck in its own web. Students share their draft with another pair using the explanation checklist for feedback. Students then rework, proofread and conference with a different group.

Return to the graphs constructed at the beginning of the unit. Take a second survey.
Put the new data on a poster board showing the way students feel about spiders now that they have completed the unit. Discuss findings.
