Technology and Engineering - Understanding Technology How 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).
Technology and Engineering Technology, such as writing or word-processing technology, is always changing. Technology progresses as peoples knowledge increases and as new needs can be satisfied. - Understanding Technology How Technology Progresses
Technology and Engineering 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. Q. What does technology have to do with science? A. Advances in technology contribute to advances in science. - Understanding Technology Q. How does science affect technology? A. Advances in science contribute to advances in technology.

Technology and Engineering - Technology Design Skills Identifying a Need When engineers identify a need, they clearly define the problem they are trying to solve.
Technology and Engineering - Technology Design Skills Researching the Problem After defining a problem, engineers need to research it fully. When engineers research a problem, they gather information that will help them in their tasks.
Technology and Engineering - Technology Design Skills Designing a Solution Brainstorming leads to several possible design solutions. Sketching and modeling help engineers visualize different designs.
Technology and Engineering - Technology Design Skills Designing a Solution In choosing the best design, engineers must evaluate constraints and make trade-offs. Engineers sometimes have to repeat one or more steps.
Technology and Engineering - Technology Design Skills Building a Prototype 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.
Technology and Engineering - Technology Design Skills Troubleshooting and Redesigning The next stage in the design process is to identify the causes of any problems and to re-design the product to address the problems.
Technology and Engineering - Technology Design Skills Communicating the Solution Engineers must communicate to consumers how a product meets their needs. They must also communicate with those involved in bringing the product to consumers.
Technology and Engineering - Technology Design Skills Patents 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.
Technology and Engineering Sequencing Sequence 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 Process Identify the need. Research the problem. Design a solution. Build a prototype. Troubleshoot and redesign. Communicate the solution. - Technology Design Skills

Technology and Engineering Working on the Farm The graph shows the percentage of workers who worked on farms between the years 1860 and Use the graph to answer the following questions. - Technology and Society
Technology and Engineering Working on the Farm Year, from 1860 to 2000 Reading Graphs: What factor is plotted on the horizontal axis? - Technology and Society
Technology and Engineering Working on the Farm Percentage of total workers in the United States who are farm workers Reading Graphs: What factor is plotted on the vertical axis? - Technology and Society
Technology and Engineering Working on the Farm 1860 Interpreting Data: Of the years shown on the graph, in which year was the percentage of farm workers highest? - Technology and Society
Technology and Engineering Working on the Farm 2000 Interpreting Data: In which year was the percentage lowest? - Technology and Society
Technology and Engineering Working on the Farm It decreased from about 45 percent to about 2 percent, or a reduction of about 43 percent of the total workforce. Calculating: By how much did the percentage of farm workers change between 1860 and 2000? - Technology and Society
Technology and Engineering Working on the Farm The percentage of farm workers in the total workforce of the United States has declined steadily from 1860 to Drawing Conclusions: What trend does the graph show? - Technology and Society
Technology and Engineering Working on the Farm 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. Inferring: Based on what you know about technological advances, how would you explain the trend shown in the graph? - Technology and Society
Technology and Engineering - Technology and Society Analyzing Risks and Benefits Should you use headphones? Evaluating the risks and benefits can help you decide.
Technology and Engineering Cause Effects As 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. Invention of air bags Positive effect: saves lives Negative effect: can cause injury or death Invention of steam-powered looms Positive effect: greater production Negative effect: loss of jobs Pesticide application Positive effect: protects crops Negative effect: harmful to plants and animals Invention of tractors Positive effect: can plow more land Negative effect: loss of farm jobs Invention of computers Positive effect: workers can do more Negative effect: quickens pace of life - Technology and Society Relating Cause and Effect
