Science



The goal of science is often to describe, explain, and predict relationships that occur naturally.
In other words, science tries to explain objects and events.
E.g., How do changes in the kind of soil affect how abundantly mushrooms grow?

Technology


The goal of technology is to try and change the relationship that exists to achieve desirable results.
In other words, technology tries to change objects and events.
E.g., how can we stop mushrooms from growing on lawns?

Science VS Technology
 A scientist would attempt to explain how the changes in soil affect how abundantly mushrooms grow.
 A technologist would attempt to develop ways to stop mushroom growth on lawns.
 These fields have much in common.
Often the information gathered by the scientist is used by the technologist to make a useful product.

The next slide contains a list of 18 ideas about this crop duster.
Some of the ideas relate to science and other ideas relate to technology.
Consider each idea carefully and place it in the appropriate column on the handout given to you by your teacher.

Society
 Society can be defined as a group, large or small, of people in a particular place and time who are linked by common goals and interests.
 Society is affected greatly by both science and technology.
 How will society be affected by the scientific and technological ideas of airplanes we just discussed?

Affects on Society
 People can travel long distances in a short period of time.
 Society will want to know the airplane is safe before they use it. Laws and standards will help ensure people’s safety.

Environment
 Science and technology have many impacts, both positive and negative, on the environment.
 How will the environment be affected by the scientific and technological ideas of airplanes we just discussed?

Affects on the Environment
 Increased pollution
 Increased use of fuel
 As humans travel globally they carry and spread disease from one area of the world to another.
 Ecosystems destroyed to build runways.
 Affects of pesticides on organisms other than the crops sprayed.

Concluding Activity
 Write down 10 technologies you use daily that you feel you could not live without.
 Consider the impact each technology has on society and the environment.
 Write down an impact for both society and the environment for each of your technologies. They can be either positive or negative impacts.

I love bathroom cleaners that are “scrub-free” chemical based cleaners.
Society: it takes me less time to clean my bathroom.
Environment: these cleaners are made of chemicals that are harmful to the environment.
