2How Does Technology Relate to Science? - Understanding TechnologyHow Does Technology Relate to Science?Science is the study of the natural world to understand how it functions. Technology, on the other hand, changes, or modifies, the natural world to meet human needs or to solve problems. For example, understanding the physics of light (science) led to the development of optical fibers and endoscopes (technology).
3How Technology Progresses - Understanding TechnologyHow Technology ProgressesTechnology, such as writing or word-processing technology, is always changing. Technology progresses as people’s knowledge increases and as new needs can be satisfied.
4Previewing Visuals - Understanding Technology When you preview, you look ahead at the material to be read. Preview the figure Science and Technology. Then write two questions you have about the diagram in a graphic organizer like the one below. As you read, answer your questions.Science and TechnologyQ. What does technology have to do with science?A. Advances in technology contribute to advances in science.Q. How does science affect technology?A. Advances in science contribute to advances in technology.

7Identifying a Need - Technology Design Skills When engineers identify a need, they clearly define the problem they are trying to solve.
8Researching the Problem - Technology Design SkillsResearching the ProblemAfter defining a problem, engineers need to research it fully. When engineers research a problem, they gather information that will help them in their tasks.
9Designing a Solution - Technology Design Skills Brainstorming leads to several possible design solutions. Sketching and modeling help engineers visualize different designs.
10Designing a Solution - Technology Design Skills In choosing the best design, engineers must evaluate constraints and make trade-offs. Engineers sometimes have to repeat one or more steps.
11Building a Prototype - Technology Design Skills Prototypes are used to test the operation of a product, including how well it works, how long it lasts, and how safe it is to use.
12Troubleshooting and Redesigning - Technology Design SkillsTroubleshooting and RedesigningThe next stage in the design process is to identify the causes of any problems and to re-design the product to address the problems.
13Communicating the Solution - Technology Design SkillsCommunicating the SolutionEngineers must communicate to consumers how a product meets their needs. They must also communicate with those involved in bringing the product to consumers.
14Patents - Technology Design Skills A patent is a legal document issued by a government that gives the inventor exclusive rights to make, use, or sell the invention for a limited time.
15The Technology Design Process - Technology Design SkillsSequencingSequence is the order in which a series of events occurs. As you read, make a flowchart that shows the steps in the technology design process. Put the steps of the process in separate boxes in the flowchart in the order in which they typically occur.The Technology Design ProcessIdentify the need.Research the problem.Design a solution.Build a prototype.Troubleshoot and redesign.Communicate the solution.
17Working on the Farm - Technology and Society The graph shows the percentage of workers who worked on farms between the years 1860 and Use the graph to answer the following questions.
18Working on the Farm - Technology and Society Reading Graphs: What factor is plotted on the horizontal axis?Year, from 1860 to 2000
19Working on the Farm - Technology and Society Reading Graphs: What factor is plotted on the vertical axis?Percentage of total workers in the United States who are farm workers
20Working on the Farm - Technology and Society Interpreting Data: Of the years shown on the graph, in which year was the percentage of farm workers highest?1860
21Working on the Farm - Technology and Society Interpreting Data: In which year was the percentage lowest?2000
22Working on the Farm - Technology and Society Calculating: By how much did the percentage of farm workers change between 1860 and 2000?It decreased from about 45 percent to about 2 percent, or a reduction of about 43 percent of the total workforce.
23Working on the Farm - Technology and Society Drawing Conclusions: What trend does the graph show?The percentage of farm workers in the total workforce of the United States has declined steadily from 1860 to 2000.
24Working on the Farm - Technology and Society Inferring: Based on what you know about technological advances, how would you explain the trend shown in the graph?The progress of technology, including the advance of tractors and other machinery, reduced significantly the need for workers on farms over the last 150 years.
25Analyzing Risks and Benefits - Technology and SocietyAnalyzing Risks and BenefitsShould you use headphones? Evaluating the risks and benefits can help you decide.
26Relating Cause and Effect - Technology and SocietyRelating Cause and EffectAs you read, identify one positive and one negative effect of each technology discussed in this section. Write the information in a graphic organizer like the one below.CauseEffectsPositive effect: can plow more landPositive effect: workers can do morePositive effect: protects cropsPositive effect: saves livesPositive effect: greater productionInvention of air bagsInvention of computersInvention of steam-powered loomsInvention of tractorsPesticide applicationNegative effect: harmful to plants and animalsNegative effect: quickens pace of lifeNegative effect: can cause injury or deathNegative effect: loss of farm jobsNegative effect: loss of jobs
