In this part of the unit on ratios and proportions, students will use ratio language to write ratios in a real-world context.  They will be architects who are designing an amusement park, an aquarium research center, or a baseball stadium.  Students will write equivalent ratios and use them to make their building a physically safe space that meets all building requirements.  During this project, students will also be converting between units (e.g., inches and feet) as they find equivalent ratios.  After students have made all of their calculations, they will analyze another set of design specifications and create a presentation explaining whether these new specifications would result in an architecturally safe building.  Students will use their math calculations from the design challenge to justify their answers.
