In this article the author describes the "Derby Design Day" project--a project that paired high school honors physics students with second-grade children for a design challenge and competition. The overall project goals were to discover whether collaboration in a design process would: (1) increase an interest in science; (2) enhance the understanding of science concepts; and (3) address elementary student misconceptions of high school. Herein the author describes how she developed the project and then shares elements of the outcome of the program, along with areas identified for improvement and expansion.
