Assess students' ability to design a simple backyard rain garden to reduce stormwater runoff. Tasks: select appropriate local native plants and justify choices for function (pollinator support, deep roots, seasonal water tolerance); estimate garden size from given roof area and rainfall by calculating expected runoff and required infiltration/ponding area; produce a basic layout sketch and a clear maintenance plan (schedule, tools, seasonal tasks, and monitoring). Emphasize applied problem-solving and clear justification.
