Technology and Engineering

Objectives for today! Explain how science, technology,

engineering, and mathematics are closely related.

Identify ways that technology responds to social, political, and economic needs.

Explain the engineering design process for developing new technologies.

Describe how technology has intended benefits and unintended consequences.

What do you think technology is?

Let’s make a list…

What is technology? Technology-the products and processes that

are designed to serve our needs. Technology also refers to the tools and

methods for creating these products and processes. Examples

A memory chip is technology, but the tools and process used to make the memory chip is also technology.

Compared to an IPod touch a computer is old technology. However compared to a typewriter a computer is new technology. A typewriter is newer technology than a pencil or pen.

How Does Science Relate to Technology?

• Engineering uses scientific knowledge to develop technologies.

• Engineers use science and mathematics to create new technologies that serve human needs.

• There are many different types of engineers who develop a variety of very different products.

How Does Science Relate to Technology? continued

• Engineering is the process of creating technology.

• Scientists, inventors, business owners, artists, and even students have also engineered new technologies.

• Anyone can follow the engineering design process to solve a problem or address a need.

What is the Engineering Design Process?

• The engineering design process has similarities to the scientific process.

• Like the scientific process, some steps may require repeating or modifying to fit different needs.

What is the Engineering Design Process? continued

Step 1 Ask: Identifying and Researching a Need

• Engineers define and write the need or problem they are trying to solve.

• For example, the problem may be to make clothing that repels water so that explorers can work, even in Antarctica.

• Research provide engineers with information for problem solving.

Step 2 Imagine: Developing Possible Solutions

• Brainstorming is the process in which a group of people share ideas quickly to promote additional ideas.

• Sometimes a possible solution to the problem comes from these ideas or it may take more time and thought.

Step 3 Plan: Making a prototype

• A prototype is a test model of the product.

• Prototypes allow engineers to see if their design works the way they expect it to.

Step 4 Create: Testing and Evaluating

• Prototypes are tested and evaluated.

• Engineers complete a cost-benefit analysis to make sure that the cost of designing and producing the new product is worth its benefit.

• For example, it may only makes sense to produce a new product if it is not too expensive to produce.

Step 5 Improve: Modifying and Retesting the Solution

• If a prototype was not successful or did not work well, 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 before they begin the design process again.

What is the Engineering Design Process? continued

• Communication Engineers often need to share their successes, failures, and reasoning with others.

• Engineers may explain and promote the technology to customers, or they may communicate with the public through news releases, advertisements, or journals.

Technology and Society

• Technology provides solutions for many types of social, political, and economic needs.

• Intended Benefit An intended benefit is the positive purpose for which a technology is designed to be used.

• Unintended Consequences Unintended consequences are uses or results that engineers do not purposely include in the design of products. An unintended consequence can be beneficial.

Intended benefits Unintended consequences

Bioengineering

• Bioengineering is the application of engineering to living things, such as humans and plants.

•Bioengineered technologies can be classified as either assistive or adaptive.

• Assistive technologies are developed to help organisms without changing them.

•Adaptive bioengineered products change the living organism.
