Lesson 1: We Need Engineers, Engineers Need Us

Discovering Design

Modern products have evolved through innovation and iteration.

 Engineers make this happen.  What other products have evolved?

Record thoughts and observations in your engineering notebook.

Modern products evolved through innovation and iteration.

 How have cameras evolved? Give three ways.  What kinds of cameras do you have?  Name five different uses of cameras besides

taking selfies.

Imaging began with the camera obscura.

 Camera = “chamber”  Obscura = “dark” Record thoughts and observations in your engineering notebook.

How does it work?

Add to the notes you’ve already made in your engineering notebook.

How do you use this technology practically every second you are awake?

Why did this technology lead to the invention of the camera?

Camera obscura technology existed People had a want or need to… what? Science/Technology + Societal Need 

Product Design

Record thoughts and observations in your engineering notebook.

Engineering happens when technology meets societal needs.

Scientific Knowledge and Technology

A body of scientific knowledge and technology exists. Society has needs that can be addressed by science and technology.

Societal Needs

The application of scientific knowledge and technology for the benefit of humankind is the

domain of engineering.

Unit Project Assignment: The Evolution of Imaging

 For your assigned time period (between the late 1800s

and today) create a timeline with important dates and events in society and imaging technology.

 At the end of the unit, each team will present its time

period and the class will discuss the overall evolution of imagery.

Record thoughts and observations in your engineering notebook.

 Innovation – creates something new that meets the needs

• f the market in new and much better way

 Iteration – makes a gradual improvement to something that

exists (e.g., makes it stronger, faster, less expensive)

 Give two examples of product innovations and two

examples of iterations.

Innovation and iteration are improvements in technology.

Time Advances Iteration – Slower improvements Innovation – Rapid technical improvements

Innovation tends to improve performance rapidly.

Time Advances Innovation Innovation or “Leap”

 I will review your engineering notebooks periodically.  Make it easy to find your work so that you can get full credit.  Place a post-it note on the appropriate page in your notebook to

denote the following item:

 Camera Obscura Phenomenon notes

 Place a post-it in your notebook for anything else you are

particularly proud of or would like me to see.
