In this unit, student design teams create a plan for an Eco Park that achieves multiple goals for their client, International Association of Athletic Federations (IAAF). Students gain knowledge about the ecology of various ecosystems and explore both positive and negative ways in which humans impact the environment. They brainstorm solutions for reducing detrimental effects when designing their parks. While design the eco-park, students must focus on sustainability, minimizing negative environmental impacts, and promoting active lifestyles. Students teams construct 3-D and topographic maps that require knowledge of the coordinate system, metric conversions, area, and accurate measurement. Finally, students demonstrate their understanding through the creation of informative field guides in addition to the park maps.
