Integrated Science 9

Scientific Discovery & Scientific InsightMany scientific breakthroughs

throughout history have changed the course of human history

★Discovery of microorganisms that cause disease○ Let to studies in how to avoid spread of diseases and cures

★Watson and Crick in discovered the structure of the DNA double helix○ Had helped doctors better understand genetic

diseases/disorders○ Will hopefully lead to prevention of cancer and heart disease

Video: How simple ideas lead to scientific discoveries - Adam Savage

What is technology?

★Science and technology are often used interchangeably

★Science is an exploration process

★Technology is what results when scientific knowledge of materials and processes are used to benefit people

Technology

Technology can be:Any human-made object

Any method or technique for making any object or tool Object or skills needed to operate a human-made object A system of people or objects used to do a particular task

Technology and Time

What is considered technology today maybe considered an antique tomorrow

Global Technological NeedsTechnological solutions are different for

different groups of people People in underdeveloped

countries need technology that helps supply basic needs like food, water, and basic health care

People in industrialized countries need technology that improve the quality of life since basic needs are met

Bioengineering and FoodCan technology stop world hunger?

Is there enough food and we just aren’t getting it to everyone who needs it?

Agricultural biotechnology is a collection of techniques and engineering used to create, improve, or modify plants, animals, and microorganisms*GMOs

Round Table

Turn to Page 44 in your text and read about the technologies described there.

In your groups, discuss the following question:

If you were in charge of bringing technology to a developing country and could only bring one technology a year, in what order would you bring the technologies? Why?

*One member of your group should write a summary of your discussion to share with the class.

Journal Entry

Technological advances range from in the invention of the ballpoint pen to the invention of the television.

Think about the technological advancements that you have seen in your life.

How has technology changed your life?

Safety and Responsibility

Society and Technology

Science and Society are closely connected.

Advances in technology will bring about changes in a society.

Society will affect how new technologies develop

Automobiles

Automobile Invented

Changes in technology and manufacturing

increase the number of people with cars

Fossil-fuel emissions increase

As fuel prices rise, research into

technology that will make cars for fuel efficient begins.

Fossil-fuel consumption

increases

Hybrid cars become available

Ways Society Drives TechnologyConsumer Acceptance● Purchasing technology in one way that

people support the development of technology

Personal Values● People will support development of

technology that agrees with their personal values○ Indirectly

■ May elect officials that support research ○ Directly

■ May give money directly to fund research efforts

Economic Influences

● Funding is an important component of scientific research.○ Before money is given to develop a new

technology one may ask:■ What is the benefit?■ What will it cost?■ Who will by it?

● Methods of Funding○ Federal Government○ Private Foundations○ Private Industries

Safety and ResponsibilityIt is important that any new technology

not destroy the environment● Pros and cons of all technologies must

be considered○ Environmental Issues○ Moral and Ethical Issues

Developing Technology

Who develops technology? ● Scientists

○ Scientist are involved in research and discovery

○ Don’t always know how the results of their work will be used

○ Can work in the field or in labs conducting research

● Engineers○ Bring technology to the consumer○ Use scientific information to solve a problem

Technological problems found by engineers will often drive additional research by scientists

Finding Solutions

● Identify the problem○ Have a focuses goal...avoid being too broad

● Proposing solutions○ Must be aware of limitations

■ Constraints● Funding● Materials● Cost● Time● Complying with laws and regulations

Finding Solutions

● Performance testing○ Drawings, models, and computer simulations○ Prototypes (full-scale models used to test a

product)■ Made in pilot plants (smaller versions of

the real production equipment

● Limits System Failure■ Performance testing■ Redundant systems■ Control systems

Intellectual Property

• Innovation is costly and time consuming

• A company will want a return on their investment

• Patents will give creator exclusive rights to make, use, and sell the product for a number of years. o In the US, patents last 20 yearso Granted by the United States Patent and Trademark Office in

exchange for public disclosure of the inventiono A trademark is a word, phrase, symbol, and/or design

that identifies and distinguishes the source of the goods of one party from those of others.  

o A copywrite protects works of authorship, such as writings, music, and works of art that have been tangibly expressed.
