What Is Science?
 Science is the process of finding answers to
questions about the natural world so we could
better understand it.
 Questions science attempts to answer
- How did the universe form?
- How will Earth change in the future?
- How did life evolve on Earth?
- What is the nature of matter?
Major Fields of Science
***Copy fig 13-1 in your notebook

LIFE SCIENCE

-Botany, Zoology (related sciences)

EARTH SCIENCE

Astronomy, Meteorology, Geology

PHYSICAL SCIENCE

Chemistry, Physics
Fields of Science

Most technological advances involves knowledge from many fields
of science

EXAMPLE- The artificial heart
-invented from knowledge of biological science and physical science
(mechanical principles)
REF. to fig 13.2 in your text
How Does Science and Technology
Advance Each Other ?

Science advances technology and technology
advances science

EVERY technological advance is based on scientific
principles in some way

EX. Discovery of how light refracts or bends when it
passes through different types of lenses led to the
inventions of:
-
TELESCOPE
-
MICROSCOPE
-
EYEGLASSES
Table 13-1 Relationship
of Scientific
Principle and Technology
SCIENTIFIC PRINCIPLE
-Low temp. kills or
reduces growth of
microorganisms
-Sunlight=energy
-Splitting atoms of
radioactive elements
produce heat
- Every action has an
equal and opposite
reaction

TECHNOLOGICL
DEVICE/PROCESS
-Refrigerators & freezers

-Solar heating and solar
cells
-Nuclear power plants
- Rocket and jet engines
SEARCH FOR KNOWLEDGE
 Drives
science and technology
 Questions of who we are/why are we
here, etc.
 Development of new technology to
answers these questions
-EX. Improved and larger telescopes help
us explore the universe
_Can you think of any other examples?
Technology as a System
SYSTEM
= a group of related parts that work together for a
common purpose
• The parts of a system act in a series of steps:
-INPUT
-Compare and Control
-PROCESS
-Feedback

What about a Home Heating
System?
 Input=
Desired Temp.
 Comparison and control=
(turns furnace on and off)
 Processing=
Furnace burning fuel
 Output=
Heat
What other systems can you think
of?

The world

The universe

Biological

Physical

Everyday life!

Using Technology

Riding a school bus

T.V., I Pods, Computers, Calculators.

Telescopes, Microscopes

Machines

ALMOST EVERYTHING WE DO!!
In the Environment
Negative –
Using electricity consumes nonrenewable natural
resources and cause air and water pollution
PositiveSewage treatment plants remove harmful
materials from waste water
COPY TABLE 13-3 in your notebook
Process Skill P. 367- 368
Using a Radio Communication
Time Line

Marconi- “Father of Radio”
-wireless transmission and reception of a telegraph
- PLEASE READ and review timeline on Page 368
3/30/15
AIM: How has science and
technology effected Society?
 DO
NOW: Copy table 13.4 page 373
in your notebook
 Homework: Page 379 Part 2 questions
Science, technology, and society
are constantly interacting and
affecting one another

SOCIETY= a group of individuals who generally think and interact in
similar ways

EXAMPLE: Scientific discoveries about the structure of matter led to
many technological discoveries developments, including the
production of the micro- processors on tiny silicon chips.

These chips made it possible many products that affected society
by improving health care, communication and transportation

What are some other examples can you think of?
Negative Effects and the Attitude
of society

SOME EXAMPLES OF NEGATIVE EFFECTS

Environmental pollution

Garbage

Hazardous waste

Public opinion has pushed science to find a cure for AIDS, but have also
discouraged the use of animal testing for cosmetic safety

Public attitude determines if an existing technology is accepted

EX. Nuclear energy has advantages and disadvantages
-some countries have banned it, others generate much of their electricity
with nuclear energy
Historical, Political and Social
Factors that Affect Science

Historical- Galileo built the first telescope and was able to
conclude that the sun was the center of the solar system and Earth
traveled around it (HELIOCENTRIC)

The church did not believe this and imprisoned him

Political:10/4/57 – Soviet Union place Sputnick 1 into Earths orbit
which threatened the United States, so in Jan.1958 the U.S. launched
the Explorer 1

This space race/competition led to a push to improve science
education

Social: Genetic engineering of crops to decrease world hunger,
And biotechnology of replacing diseased genes with healthy genes
-BUT has caused controversy
Global Effects of Technology

Chernobyl= released radiation to several neighboring countries near
the Ukraine . Crops, livestock and water were contaminated

Acid rain- if air pollution caused in the Midwest, prevailing winds
cause acid rain in New York, Canada, New England

Greenhouse gases (carbon dioxide, methane) trap heat close to
Earth

Burning of fossil fuels release large amounts of CO2

GLOBAL WARMING: increase in temp. caused from an increase in
greenhouse gas emission.
-Glacier melting=causing high sea levels that stress humans and other
organisms
POSITIVE EFFECTS


Communication satellites allow people all over
the world to interact
Predicting natural disasters

Fig 13-9

CLOSURE: Name 3 specific examples of how
technology has helped and or harmed society

Homework page 379 Part 2 questions
3/31 AIM: How does making
decisions about technology affect
everyday life

DO NOW: Give examples about how you have
more choices in your life because of the
products of technology?

HOMEWORK: Page 383 PART 1 questions
Technology Increases Our Choices

Cable and Satellite television, MP3 players
 Leisure
activities –fig. 13.10
-Transportation (planes, train, cars, etc)
- Shoppes have choices for home, kitchen
and shop appliances (microwaves,
computers, cell phones, laser guide saws,
shopping online
ASSESSING TECHNOLOGY

Benefits and burdens: Ex. Automobiles have given
people greater mobility and contribute to our nations
wealth-** BUT have contributed to air pollution and
caused injuries and deaths in accidents

Who monitors the effects of technological
devices/processes? For example medical treatments,
food additives, industrial chemicals
-Government agencies, public interest groups, voters

TABLE 13-5 LIST at least 4 technological processes or
devices including the benefits and burdens
TECHNOLOGY AND DECISION
MAKING

We must consider long and short term effects

EXAMPLE: Benefits of x-rays outweigh the long
term risk of exposure to radiation

EXAMPLE: Using unleaded gasoline (less
pollution)

EXAMPLE: Recycling (reduces waste and
conserve resources)
4/1/15 AIM: How has technology been a
benefit for the medical industry

DO NOW: Name and describe 3 ways
technology has been a positive effect on the
health of society
