Concept: Learners will play like they are rattlesnakes that are trying to conserve their venom by only biting (or injecting venom) into things they can eat.

Goals (Not measurable): Learners will get a feel for having to make a fast choice about whether to bite and inject venom. They will understand some of the reasons a rattlesnake may bite something too large to eat, as well as the reasons why a rattler might give a "dry bite" (where they do not inject any venom).

Objectives (Measurable): Learners will be able to explain the times when a rattlesnake is likely to rattle. They will be able to list three things a rattlesnake can eat and three things it might bite, but not eat.
