Summary

Students follow the steps of the engineering design process (EDP) while learning about assistive devices and biomedical engineering. They first go through a design-build-test activity to learn the steps of the cyclical engineering design process. Then, during the three main activities (7 x 55 minutes each) student teams are given a fictional client statement and follow the EDP steps to design products—an off-road wheelchair, a portable wheelchair ramp, and an automatic floor sweeper computer program. Students brainstorm ideas, identify suitable materials and demonstrate different methods of representing solutions to their design problems—scale drawings or programming descriptions, and simple models or classroom prototypes.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

Engineering Connection

Engineers improve the quality of life for people around the world and they follow the steps of the engineering design process as a widely accepted way of arriving at desirable solutions to identified problems. The activities in this unit guide students through the engineering design process as they apply basic engineering concepts to real-world design problems. Through the development of assistive devices, students are exposed to the humanitarian aspects of engineering. Examples of advanced technology applications abound, for example, cutting edge prostheses such as Dean Kamen's "Luke Arm" or the redesign of traditional prosthesis to improve comfort and user interface.

Unit Overview

Students are introduced to the major steps of the engineering design process (EDP) and some of the roles engineers play in our world. After introducing the EDP, students are teamed up with one or two other students. Each student team spends approximately seven days working on each module—an engineering project focused on the humanitarian side of engineering. After the seven days, groups move onto their next engineering design project. This pattern repeats until students have completed all three modules. While each learning module focuses on a different field of engineering, all share the common theme of biomedical engineering through the design of assistive devices.

Educational Standards

Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.

All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org).

In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

See individual lessons and activities for standards alignment.
