This classroom activity from TeachEngineering, a collaborative online digital library, engages students in three-dimensional learning as they explore the phenomenon of human impact on a selected environment. Students use engineering design to plan a housing community within a desert, deciduous forest, or grassland, while also considering ways to protect native species. The lesson uses the 7E instructional model (Elicit, Engage, Explore, Explain, Elaborate, Evaluate, Extend.) Students work in teams of four where each student has a particular role (project manager, civil engineer, environmental engineer, graphic designer.) As a team, students conduct research on their selected biome, on environmentally conscious engineering plans and designs, and on the needs of native species. Students brainstorm a variety of plans for the housing community, evaluate their ideas, and select their best designs to create a pamphlet, which they then present to the class. Students use a provided rubric to peer review the presentations based on their creativity as well as consideration of the designs’ benefits to both people and native species. Afterwards, students regroup in teams to consider feedback and to come up with at least two ways to improve their design. Throughout the activity, students document their work in research journals. Extension ideas are offered to encourage students to explore beyond the lesson. Links are provided to additional resources for both learning and assessment.
