Impact of inventions anddiscoveries
Answers
Answer:
A promotional painting by George Inness will introduce students to a new invention from the nineteenth century: the locomotive. Then, they will research another invention from the nineteenth-century and the impact it had on the lives of the American people. Students will illustrate two advertisements: the first as a promotion of the positive impact of the invention and the second as a public service announcement warning about potentially harmful side effects.
Answer:
In Inventions 1: Edison and the Light Bulb, students learn how inventions are created to solve problems or improve the way things are done. The revolutionary invention of the light bulb by Thomas Edison is used as an example.
In Inventions 2: The Impact, students focus on the process of inventing, particularly on what short- and long-term issues inventors have to consider before developing an invention. They examine a number of other revolutionary American inventions and are encouraged to evaluate the effects of their own invention ideas in terms of their usefulness and public impact.
At this early level, it is important to introduce students to the idea of technology, and help them to identify its various forms and ongoing effects on society. It is also worthwhile to help them see that technology, including the invention of processes and tools since the beginning of time, shows that people have some control over their destiny and can handle problems by searching for better ways to do things, inventing solutions, and taking risks. (Benchmarks for Science Literacy, p. 53.)
Having students take part in simple design projects gives them interesting opportunities to solve problems, use tools well, measure things carefully, make reasonable estimations, calculate accurately, and communicate clearly. They are also given the opportunity to ponder the effects that their inventions or projects might have, particularly on their surroundings.
