I use this activity in my high school Zoology class. We have a unit on Invertebrates. The lab component of this unit involves identifying preserved invertebrate specimens in jars. Students work for several weeks with the specimen jars. Early in the unit students sketch the jars. Next students start to learn characteristics about the animal groups, and sort the jars, and start to look for identifying characteristics that help to distinguish between similar-looking invertebrates.
We do this scavenger hunt towards the end of the units. Students make review cards with some of the animals we study. As a class, we get together in groups and use the review cards in review games to practice identifying the different animals.
This activity comes with the above teaching notes, a rubric, and an editable student assignment sheet that explains how to set up the scavenger hunt. In my class, this is set up as an optional extra assignment with some extra credit points possible. There is a list of animal groups, and students create flash cards with pictures on one side and characteristics on the other. These can be used in many review games (3 sample ideas included in teaching notes).
You will receive a 3 page Word document with teaching notes, a simple grading rubric, and a student assignment page.
