3. What Is Technology?  Technology refers to the products and processes that are designed to serve our needs.  Technology refers to the products and processes that are designed to serve our needs. Technology also refers to the tools and methods for creating these products. Technology also refers to the tools and methods for creating these products. Technology applies to any product, process, or knowledge that is developed to meet a need. Technology applies to any product, process, or knowledge that is developed to meet a need.

4. Engineering is the process of creating technology. Engineering is the process of creating technology. Scientists, inventors, business owners, artists, and even students have also engineered new technologies. 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. Anyone can follow the engineering design process to solve a problem or address a need.

5. How Does Science Relate to Technology? Engineering uses scientific knowledge to develop technologies. Engineering uses scientific knowledge to develop technologies. Engineers use science and mathematics to create new technologies that serve human needs. 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. There are many different types of engineers who develop a variety of very different products.

6. What is the Engineering Design Process? The engineering design process has similarities to the scientific 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. Like the scientific process, some steps may require repeating or modifying to fit different needs.

7. Step 1 Ask: Identifying & Researching a Need Engineers define and describe the need or problem they are trying to solve. Engineers define and describe the need or problem they are trying to solve. Research provides engineers with information for problem solving. Research provides engineers with information for problem solving.

8. Step 2 Imagine: Developing Possible Solutions Brainstorming is the process in which a group of people share ideas quickly to promote additional ideas. 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. Sometimes a possible solution to the problem comes from these ideas or it may take more time and thought.

9. Step 3 Plan: Making a prototype A prototype is a test model of the product. A prototype is a test model of the product. Prototypes allow engineers to see if their design works the way they expect it to. Prototypes allow engineers to see if their design works the way they expect it to.

10. Step 4 Create: Testing and Evaluating Prototypes are tested and evaluated. 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. Engineers complete a cost-benefit analysis to make sure that the cost of designing and producing the new product is worth its benefit.

11. Step 5 Improve: Modifying & 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. 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. It is important that the engineers consider what was learned from the first prototype before they begin the design process again.

12. Step 6 Communication: Engineers often need to share their successes, failures, and reasoning with others. 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. Engineers may explain and promote the technology to customers, or they may communicate with the public through news releases, advertisements, or journals.

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

15. What is Bioengineering? The application of engineering to living things, such as humans and plants, is called bioengineering. The application of engineering to living things, such as humans and plants, is called bioengineering. Bioengineered technologies can be classified as either assistive or adaptive. Bioengineered technologies can be classified as either assistive or adaptive.

16. Assistive technologies are developed to help organisms without changing them. Such as glasses, contacts, crutches, wheel chair, cane, hearing aid Assistive technologies are developed to help organisms without changing them. Such as glasses, contacts, crutches, wheel chair, cane, hearing aid Adaptive bioengineered products change the living organism. Such as cochlear implant, pace maker, organ transplant, bioengineered products (corn) Adaptive bioengineered products change the living organism. Such as cochlear implant, pace maker, organ transplant, bioengineered products (corn)
