What is Engineering?
• Engineering is the process of creating technology.
• Name some examples of technology that engineers, scientists, and inventors have created.

What is Bioengineering?
• Bioengineering is the application of engineering (technology) to living things, such as humans and plants.
• Bioengineers look at problems that occur in living things and invent technology that will help with these problems.

Assistive Bioengineering
• Technology that is developed to help organisms, but DOES NOT change them.
• ASSIST = HELP
• Examples:– Eyeglasses– Wheelchairs– Antibiotics

Adaptive Bioengineering
• Technology developed to help living organisms and DOES change them.
• ADAPT = CHANGE
• Examples:– Lasik Eye Surgery– Knee replacement– New strains of crop
in agriculture

Adaptive or Assistive????
• On the back of your notes make 2 columns labeled Adaptive and Assistive
• Write the name of the item you see underneath the type of bioengineering you think it is.
• Remember: Assist = Help
Adapt = Change

Assignment:• Choose one adaptive bioengineering
technology and one assistive bioengineering technology to draw.
• Divide your paper into two sections and draw and color each.
• Label the item and write one sentence on how each piece of technology can help organisms in their daily lives.

Engineering Process
• Objective:
How do we know that the engineering design process involves an ongoing series of events?
![Page 21: Adaptive and Assistive Bioengineering Objective: How can I describe and explain adaptive and assistive bioengineered products?](https://reader030.vdocuments.mx/reader030/viewer/2022032611/56649e875503460f94b8acd2/html5/thumbnails/21.jpg)
Engineering Process
• Step 1: ASK: Identifying and Researching a Need
• Example: The problem may be to make clothing that repels water so that explorers can work, even in Antarctica.
![Page 22: Adaptive and Assistive Bioengineering Objective: How can I describe and explain adaptive and assistive bioengineered products?](https://reader030.vdocuments.mx/reader030/viewer/2022032611/56649e875503460f94b8acd2/html5/thumbnails/22.jpg)
Engineering Process
• Step 2: IMAGINE: Developing Possible Solutions
• Includes: Brainstorming of ideas.
![Page 23: Adaptive and Assistive Bioengineering Objective: How can I describe and explain adaptive and assistive bioengineered products?](https://reader030.vdocuments.mx/reader030/viewer/2022032611/56649e875503460f94b8acd2/html5/thumbnails/23.jpg)
Engineering Process
• Step 3: IMAGINE: Making a Prototype
• Prototype: a test model of the product. Allows engineers see if their design works the way they expected.
• Example: clothing that is water proof.
![Page 24: Adaptive and Assistive Bioengineering Objective: How can I describe and explain adaptive and assistive bioengineered products?](https://reader030.vdocuments.mx/reader030/viewer/2022032611/56649e875503460f94b8acd2/html5/thumbnails/24.jpg)
Engineering Process
• Step 4: CREATE: Testing and Evaluating
• Determines whether the technology does the job is was designed to do.
• Cost-benefit analysis: determining whether the cost of doing something is worth the benefit provided.
![Page 25: Adaptive and Assistive Bioengineering Objective: How can I describe and explain adaptive and assistive bioengineered products?](https://reader030.vdocuments.mx/reader030/viewer/2022032611/56649e875503460f94b8acd2/html5/thumbnails/25.jpg)
Engineering Process
• Step 5: IMPROVE: Modifying and Retesting the Solution
• If the prototype was not successful, then scientists need to find a new solution.
