Science, technology, engineering, and mathematics (STEM) educators are facing the challenge of attracting more students. The disparity between the need for engineers and the enrollment of engineering students is growing (Genalo, Bruning, & Adams, 2000), and career aspirations of high school students are inconsistent with the employment projections for engineering-related careers (Sanoff, 2001). One solution to this problem is to infuse engineering content into K-12 curriculum. The curriculum unit presented in this article introduces middle school students to basic engineering concepts, i.e., the engineering design process, through an activity of making recycled paper. Hands-on activities and classroom presentations are combined, and the process of engineering design and mathematical analysis is presented in a real-world context.
