This practical article reports an intriguing diorama project for third grade elementary students (ages 8-9 years). Students worked as partners to create dioramas of given ecosystems made in pizza boxes. Then, students rolled a die to determine a change in some environmental factor that affected the ecosystem. The students discussed how this change affected the ecosystem and made a second part of their diorama showing the ecosystem after the change. Finally, students made class presentations concerning their dioramas and ideas. A rubric for assessing the projects is included. Results of this science project indicate that students became deeply engrossed in their work, successfully generating cause and effect explanations and altered ecosystems.
