This lesson asks students to devise a solution to the challenge of a decrease in pollinator availability for crop production. The first goal is to introduce students to justified design, which occurs when design choices for an engineering solution are based on evidence collected from preliminary investigations and understanding of scientific and mathematical principles. The second goal is for students to develop mathematical thinking skills through data analysis. The third goal is to provide the opportunity for students to gain more experience with the design cycle. This lesson is recommended to be done within an ecosystem unit. A materials list, teacher background information, assessments, and outcomes are provided.
