The Laramie High School Intro to Engineering Design (IED), taught by LHS math teacher Ariane Eicke, has been learning how to reverse engineer small objects these past few weeks.

For one of their last projects of IED, students were required to learn how to reverse engineer different objects.

Mostly small objects that are easy to disassemble and measure were used. From that point on they would design each object on a computer.

Each group was able to choose their own objects. One group took a flour sifter and was able to take it apart and redesign it on their computers.

Another group used a fidget spinner as their project.

“It was cool how so many things are made of so many parts. It helped me learn how to make things more efficient,” Jenniffer Adland said, one of those working on the fidget spinner. 

Mostly small objects that are easy to disassemble and measure were used.

LHS freshman Gabe Byrd worked on a mini slot machine.

“Usually making these types of projects it takes most the class about a week to fully finish our final structure,” Byrd said.

Sophmore Spencer Canen said they were planning on engineering a house after the most recent project.

 “Sometimes it’s difficult to get measurements to make sure everything will go well together such as smaller parts and angles,” Spencer said.

When working on one project Spencer said that at one point he had an odd angle to find that took most of every day until the project was finished.

“Tools that were handed to us for this project included calipers rulers protractors and any other necessary tool that could be brought in by either the teacher or from home,” Canen said.

In order for the students to model on a computer, they used a program called Inventor.

Inventor is a commercial computer-aided design (CAD) and drafting software application developed by Autodesk.

The Inventor program can be used to help create blueprints for structures such as bridges, buildings, and other projects, or even create things like computer chips.

Many drafters, artists, architects, engineers and many other fields, use CAD programs to help them create precise drawings or technical illustrations.

Inventor can be used in one of two ways; in two-dimensional (2D) or can be used to illustrate something in three-dimensional (3D).

Students who are in Eicke’s class had to use 3D.

The reverse engineering unit in IED allows students to get a feel for how engineers make things better.

Engineers often must take things apart and rework them in order to make them better.

Reverse engineering allows engineers to recreate, improve, or sometimes even completely trash items that don’t work as well as intended.

This project was a Project Lead The Way (PLTW) assignment.

PLTW is an American nonprofit organization developing STEM (Science, Technology, Engineering, & Mathematics) circulations for use by elementary, middle and high schools across the United States.

PLTW is also used in next engineering class, Principals of Engineering, which works with many hands-on projects as well as computer projects.

IED works heavily with computers and teaches students how to use different programs.
