If done as pre-test activity, give a detailed description of the defining characteristics of each clip. Using your observations, predict which clips are from the same shelf-edge reef (there are 5 locations).

If done as an assessment activity, give the same detailed description of each clip, group the same location clips together, and determine which clips belong to each location.

In science, a checklist is useful when making observations. Use the glossary to create your own checklist to use when viewing the clips.
