This is a lesson plan that explores the use of weight scales and measurement by manufacturing engineers, developed to help teachers integrate engineering practices in the secondary classroom. Students will work in teams to plan and design a packaging system that generates consistent packages of marbles or paper clips. The driving question of the lesson:  How do manufacturing engineers develop systems to create consistent products that are uniform in weight or count?

The lesson follows a module format that includes objectives and learner outcomes, problem sets, student guides, recommended reading, illustrated procedures, worksheets, and background information about the engineering connections. The lesson plan and student worksheets are available for download.
