Why Lesson Planet?
In an ecology simulation, middle schoolers draw dots, representing chemicals, on green strips of paper, representing aquatic plants. After you hide the strips around the room, they pretend to be fish and collect plants as food. The total chemical dots are tabulated and transferred to orange strips, representing fish. Finally, after fish strips are hidden, students pretend to be eagles and collect fish as food. The total chemical dots are again tabulated and the effects of biomagnificaiton demonstrated. Extension and assessment activities are suggested within the plan.
