Objectives

SPI 0707.T/E.1 How does technology respond to social, political and economic needs?

SPI 0707.T/E.3 Can I compare the intended benefits with the unintended consequences of a new technology?

SPI 0707.T/E.4 Am I able to describe, explain, and develop adaptive and assistive bioengineered technology?

Technology & 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 harmful or beneficial.

Elbow Partners

With your elbow partners, take 1 MINUTE to discuss a technology. What are some intended benefits and consequences you can think of?

Intended benefit and unintended consequences

List the intended benefit and unintended consequence for each technology: Aspirin

Intended benefit- pain relieverUnintended consequence- prevents heart attacks & reduce

the severity of strokes Cars

Intended benefit- Faster transportationUnintended consequence- air pollution

DDT (pesticide) Intended benefit- kill insects and other plant pestsUnintended consequence- interfering with the reproduction

in birds and killed them; helped put bald eagles on the endangered species list

The need to know:

Bioengineering involves the use of technology to alter or improve living things.

Bioengineered technologies can be classified as either assistive or adaptive.Assistive technologies are developed to

help organisms with changing them. Adaptive bioengineered products change

the living organism.

CRICOS: 00116K

Biomedical Engineer:

Design products and procedures that solve medical problems.

These include artificial organs, prostheses, instrumentation, medical information systems, and health management and care delivery systems.

Bioengineering: Forensics

PCR machines (Polymerase Chain Reaction) allow scientists to create a vast quantity (copies) of a piece of DNA found at a crime scene.

Bioengineering in Agriculture

Bioengineering can make crops resistant to diseases, herbicides, frost, & pests.

Crops for food is altered so that it is more nutritious and better tasting.

Biofuels

• A fuel made from living things.

• Biofuels substituted for some of the gasoline burned in automobile

engines.• With the help of bacteria, ethanol can

be made from cellulose, a substance in the hard fibers of

plants

Assistive or Adaptive?

Artificial Heart

Artificial SkinArtificial Hip

Hearing Aide

Prosthetics

Exit Ticket

1. Engineers are working to develop new streetlights that can be powered using energy from the sun. The lights will cost more to purchase than existing lights, but should cost less to operate over time. What is the most likely intended benefit of this technology?

A better lighting

B longer-lasting bulbs

C an increase in fossil fuel use

D lower electrical costs for communities
