Warm Up: Each day we will begin with a question or activity to get us started!

Vocabulary

• Heavy Machinery
• Operator

What kinds of jobs could Malachi get where he could use big machines?

Think About It...

• As a kid, Malachi was fascinated by big machines and cars. Growing up in Seattle, where skyscrapers were always being built, surrounded by large machines, fueled his interest. He believes it started when he went to monster truck rallies with his older brother. Malachi has always wanted to work with these machines and dreams of a job where he can do just that.

Remember...

• The Industrial Revolution brought about significant societal changes that still have effects seen today. ​

• Life before the Industrial Revolution centered around small towns built mainly by farmers and a smaller number of those who made goods by hand. ​

• Things were traded only at a local level and at a slow pace. ​

• Once towns were connected via railways and inventions of machinery like the loom that creates fabric, society started to change. ​

• People began slowly shifting from farming to manufacturing work, from rural to urban areas, and from local goods to goods traded from all over the country.

Heavy Farming Machinery

• The biggest reason all of this could happen was the invention of heavy machinery for farming.
• Heavy machinery is a large vehicle with functions often related to earthwork and construction.
• Extensive planting and harvesting vehicles were created, and fewer people could produce more food.
• This gave a surplus of food and a lower need for so many farmers.
• This meant those who were farmers could move to urban areas to pursue jobs in manufacturing.

1906: The gas-powered tractor trailer was invented.

1920: Excavators (big machines used to move large amounts of earth) were used for mining minerals.

1886: Machines for agriculture began to be built for planting and harvesting plants.

1956: The Federal-Aid Highway Act was signed, creating a need for large machinery to build highways and bridges across the U.S. over the next 35 years.

1990: Environmental rules made heavy machinery smaller than the big machines from before. By the 2000s, these smaller machines became available for individual rentals.

An excavator - used for digging, trenching, and earthmoving.

A harvester - used to harvest grains. It can be used to reap, thresh, and winnow crops.

A construction crane - used to lift or lower objects on a construction site.

A paver - used to lay cement concrete on roads, bridges, and other places.

Heavy Machinery

• Now we have a variety of common heavy machinery we use today.
• See examples of standard heavy machinery here!

Becoming an operator can be personally fulfilling work.

• Over the next decade, an estimated 84,300 operator jobs are expected to open each year.
• In most of these positions, you can learn on the job.
• This means you can seek employment and earn a paycheck while learning the trade instead of investing your money into education and certification first.

• Heavy machinery is currently not automated machinery. This means that they need an operator to run them.
• An operator is a person who controls the functions of heavy machinery.
