REVIEW QUESTIONS
1. What are some examples of products produced by the agricultural industry?
Answer: Answers should include examples such as fabrics, plastics, medicines, paint,
leather, and glue.
2. It can be said that agriculture is the backbone of American society. Explain.
Answer: American agriculture contributes to the manufacture of automobiles,
furniture, airplanes, radios, stereos, and computers; the construction of homes, boats,
and factories, in addition to providing food for all Americans.
3. Compare the number of farms in the United States in 1940 to the number of farms
today. What has made today’s food surpluses possible despite the decrease in farms?
Answer: Answers should focus on the concept of efficiency. Efficiency means the
ability to produce with a minimum waste of time, energy, and materials. Much of that
efficiency comes from mechanization.
4. How has mechanization contributed to the increase in agricultural production
efficiency?
Answer: Machines have replaced the power of human beings and animals in the
agricultural industry.
5. What is agricultural mechanics and why are skills in agricultural mechanics important?
Answer: The invention, development, and maintenance of modern farm machinery
(agricultural mechanics) has led to great leaps in efficiency. Skills in agricultural
mechanics are necessary to keep American society afloat, since so much of American
society depends on the efficiency made possible by agricultural mechanics.

6. List five occupations that involve agricultural mechanics.
Answer: There are many occupations that involve agricultural mechanics. Examples
include the engineer who designs tractors and other farm and ranch machines, the
forester who keeps chainsaws and other equipment going, the builder who constructs
processing plants, farm buildings, and aquaculture facilities, the electrician who
installs climate controls, silo unloaders, and milling equipment, the soil conservationist
who constructs terraces to control erosion, the hardware store employee who obtains
and stocks repair parts for agricultural tools and machines., the specialist who creates
air-conditioning and refrigeration systems in processing and storage facilities, the
specialist who designs and installs drainage and irrigation systems for fields, turf,
landscaping, and golf courses, the lawn equipment service mechanic who repairs lawn
tractors, the welder who repairs farm machinery, and the mechanic who keeps diesel
trucks and machines in good repair.
7. What percentage of Americans worked in production agriculture in 1776? What
percentage worked in production agriculture in 2021?
Answer: In 1776, 90 percent of Americans worked in production agriculture. In 2021, 10
percent of Americans worked in production agriculture.
8. Identify two inventions that had a profound influence on the settling of this country
and explain the importance of each.
Answer: Examples include the McCormick reaper, which allowed one person to do the
work of several people, the Deere plow which could cut through the heavy sod of the
Midwest, and the Cotton Gin, which allowed the growing of upland cotton throughout
the South.
9. Explain the impact of refrigeration on agriculture and society.
Answer: Refrigeration utterly transformed the agricultural industry. With mechanical
refrigeration, for the first time in history, people could have fresh meats and
vegetables year-round.
10. In the past, agriculture meant to farm or to grow plants or animals. Why is such a
simple definition not possible today?
Answer: Answers should refer to the wide variety of products now produced by
American farms, including fabrics, plastics, fuels and a wide variety of other items
unthinkable in the past.

DISCUSSION QUESTIONS
1. How has the agricultural industry impacted your life?
Answer: Answers will vary based on the students’ own personal experiences. Students
should be encouraged to speak to various types of experiences, from the food they eat
to any familial or economic connection to the agricultural industry.
2. Although agriculture is considered a basic industry, how could it also be described as
complex? What are some examples of its complexity?
Answer: Answers will vary but should indicate how agricultural mechanics have
transformed the way humans live in countless ways. The complexities should include
an explanation of the global nature of the contemporary agricultural industry, the
connections with other related industries, and the interconnected products and
services which can all be considered agriculture.
3. Mechanization improves efficiencies, creates career opportunities, and provides a more
stable food supply for our society. These are all advantages. Do you think that there
are any disadvantages to mechanization? Explain.
Answer: Answers will vary but might include the use of fossil fuels to run machinery,
the corporatization of certain aspects of agriculture, and the way that animals are
treated in mechanized farms.
STUDENT ACTIVITIES
1. Interview a cooperative extension specialist for agricultural resources in your county or
city. Ask the specialist to describe the different agricultural or agriculturally related
jobs that people do in your locality.
Answer: Student experiences will vary, but it is recommended that they develop a set
of interview questions for instructor approval prior to the interview to ensure that the
conversation is both productive and helpful to the student.
2. Research inventors or inventions online. Identify the inventions that relate to
agriculture and report your findings to the class.
Answer: The results of the student research and their presentations will vary, but it is
recommended that they choose reliable resources for their research. Provide them
with a list of reliable agriculture websites at the start of the project. Some websites
might include:
