Students participate in a game where native frogs and bullfrogs compete for shelter, food, and water (habitat components). This game teaches students about the relationship between an animal and its habitat, and what effect introduced animals can have on that relationship.
The activity begins with the students being grouped into one of four groups: water, food, shelter or frogs. Each habitat component comes up with a gesture for their group. The frogs line up at one end of the play area with their backs to the habitat components who are at the other end. Play begins with the frogs deciding which habitat component they want and retrieving it from the other group. Once a frog has its habitat component, they return with it to the frog area. Both students are now frogs. This is repeated for a few rounds. Next, the teacher will introduce the bullfrogs to the activity. They will be placed on a side to form a triangle with the other groups and they will be allowed to retrieve their habitat components first. The frogs will follow, and any who are without habitat components become bullfrogs. Play continues to illustrate how an invasive species take over native species.
This activity also comes with assessment suggestions and extension activity ideas.
Mr. Bullfrog would be an excellent outdoor activity to introduce the concepts of invasive species and habitat components to upper elementary and middle school Science students.
