Students in the Design Challenge Class at Brookside Elementary School in Ossining participated in an 8-week, after-school class, The Design Challenge.  In this unit, they worked on a rock slide barrier challenge, testing the limits of a roadway protection device. They began this class with a design plan, using the engineering design process to ultimately design, build and test a working design. Students worked in groups of 3-4 to complete this project.  This short video gives an idea of their solutions.
