Chapter 1, Section 4 Engineering Design Process Standard: T/E.3 Distinguish between the intended benefits and the unintended consequences of a new technology.

Objectives: 20- explore how the unintended consequences of new technologies can impact society.

Think about it? ● Write what you think the relationship between science and technology is.

Technology ● Technology refers to the products and processes that are designed to serve our needs

Where did this technology come from? ● Engineering is the process of creating technology. ● What was engineered from the following video clip?

The Engineering Design Process ● Here’s how engineers discover and create technology.

Working Through the Process ● Step 1 ASK: Identifying and Researching a Need describe the need or problem trying to solve and researching everything about it. ● Step 2 IMAGINE: Developing Possible Solutions brainstorming ideas. ● Step 3 PLAN: Making a Prototype After the best idea is chosen a prototype is built. A prototype is a test model of the product. Prototypes allow engineers to see if their design works the way they expect it to.

Let’s keep going! ● Step 4 CREATE: Testing and Evaluating Does the new prototype do the job i t ’s designed to do. Cost-benefit analysis – Making sure the cost of doing the product is worth its benefit. ● Step 5 IMPROVE: Modifying and Retesting the Solution If a prototype was not successful the engineers would either modify their prototype or try a new solution. It is important that the engineers consider what was learned from the first prototype

Intended Benefits and Unintended Consequences. ● An intended benefit is the positive purpose for which a technology is designed to be used. ● Unintended consequences are uses or results that engineers do not purposely include in the design of products. These can be positive or negative.

In 1953, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers for use in the aerospace industry. Working in a small lab in San Diego, California, it took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40® -which stands for Water Displacement perfected on the 40th try—is still in use today. Convair, an aerospace contractor, first used WD-40® to protect the outer skin of the Atlas Missile from rust and corrosion. The product actually worked so well that several employees snuck some WD-40® cans out of the plant to use at home.

Let’s brainstorm! ● With your neighbor, list and describe the intended benefit of a cell phone. ● Then list and describe two unintended consequences (one positive and one negative) of cell phone. ● Record the results and be ready to share.

Bioengineering ● Bioengineering - is the application of engineering to living things Assistive Bioengineering is any object or system that increases or maintains the capabilities of people Adaptive bioengineering is any object or system that is specifically designed for the purpose of increasing or maintaining the capabilities of people

Adaptive - specifically designed for…

Scientific Method…a review (Remember me?) ● The ways in which scientists answer questions and solve problems are called scientific methods

Put it together… ● Using a Venn Diagram, lets compare and contrast the scientific method with the engineering design process.
