The head zoologist has six envelopes with six different invertebrate categories. Your class will divide into six teams. Each team will become an expert on one category of invertebrates. Your goal is to determine which invertebrate in your category best represents that invertebrate category for the state in which you live. You will then write an official letter to your state offices recommending the adoption of your chosen invertebrate as a state symbol for that invertebrate category. Each team will make a multi-media presentation of the information to share with all the teams, and to use as a tool to persuade an audience.
