Module 10 –Reverse Engineering
Module Overview
In this module, students analyze products. First, they focus on using reverse engineering to make good products for the
consumer by analyzing features of existing products, considering design factors that determine the ease of product assembly, and
looking at the manufacturing processes used to create products from different materials. Next, students will view reverse engineering
from the perspective of product failure, and analyze communications failures in written and visual instructions. Then, students test
different materials as they explore engineering failures related to material choice.
As students explore this topic, they develop some valuable skills: the use of logbooks, as in scientific and technical fields, to
make entries of experimental results, notes of team meetings, and meeting facilitation.

Description
Learning Goals
Students begin by looking at how
products are made and thinking
about why they are made as they are.
The first products to analyze are can
openers, in a number of different
forms. They investigate how openers
were intended to be made and which
ones would be best for people with
different needs (e.g., left- or righthanded people, or those with arthritis).
Students learn to keep notes in their
design logbooks, which they will use
throughout the module.
