Lesson Focus Lesson focuses on the use of weight scales and measurement by manufacturing engineers. Teams of students are posed with the challenge of developing a system to fill jars with a specific weight or count of products such as marbles or paperclips.
A Question of Balance explores how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count. Students explore different types of scales, and are challenged to design and build a system to deliver a uniform count or weight of marbles or paperclips into a series of four boxes or jars. They test their systems and evaluate the systems of other student teams.
Age Levels: 11-18
Learn about manufacturing engineering.

Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
Students learn how manufacturing engineers develop systems for creating consistent products. They work in a team to create a system that delivers a consistent weight or count of marbles or paperclips to a series of jars. Teams plan their system, execute the system, evaluate their own results and that of other students, and present to the class.
