Lesson Focus
Lesson focuses on how engineers have to design objects to meet the needs of users, while considering the limitations of materials, and the implications of cost.
Lesson Synopsis
The Dispenser Designs activity explores how engineers work in a team to solve problems. Students learn how materials, costs, and user needs must be weighed when designing a product, and also how the same product may be redesigned over time as materials, costs, or needs change. Students work in teams to evaluate current designs and to develop a new design for a handheld tape dispenser that can be easily operated by a person who has limited strength and only has the use of one hand. Students develop drawings, execute their dispenser design using everyday materials, and evaluate the strategies employed by other student teams.
Age Levels: 11-18
Objectives
- Learn how user needs, materials, costs, and manufacturing processes impact the design of everyday items.
- Learn about the process of product re-engineering.
- Learn about patents and ethics issues.
- Learn how engineering teams address problem solving.
- Learn about teamwork and working in groups.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- product design and engineering
- problem solving
- teamwork
