Bellwork 9-9-2014
 Get out the page in your folders with the questions.
 Do only the multiple choice question for now.
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 reliever
 Unintended consequence- prevents heart attacks & reduce the severity
of strokes
 Cars
 Intended benefit- Faster transportation
 Unintended consequence- air pollution
 DDT (pesticide)
 Intended benefit- kill insects and other plant pests
 Unintended 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.
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.
CRICOS: 00116K
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?
Hearing Aide
Artificial Heart
Artificial Hip
Prosthetics
Artificial Skin
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
