Civil
Engineers
A Civil engineer plans and constructs buildings, bridges, waterways, streets,
tunnels, dams, airports, missiles, automobiles, etc. A civil engineer needs
to know about the materials and tools she uses. She must also know about
the rocks and minerals in order to build foundations. She must also
know how to use machines such as bulldozers, cranes, and power shovels.
Civil engineers have built things such as, the Empire State Building, Hoover
Dam, Panama Canal, and the San Francisco-Oakland Bay Bridge, to name a
few.

Mechanical
Engineers
Mechanical engineers deal with mechanical power. They design, operate,
and test all sorts of machines. They work with a lot of manufacturing.
They build tings like transportation devices and engines.
Mechanical engineers have built Spinning Machinery, Gasoline Engines, and
machines for exploring the moon.

Mining
And Metallurgical Engineers
Mining and metallurgical engineers deal with minerals, such as, coil, tin,
and copper. They find them, dig them up, and process them into useful products.
A mining and mettalurgical engineer must know how to carefully dig up the
mineral. She must also know geology - the study of minerals and rocks.
A mining and metallurgical engineer must also know a bit about civil, mechanical,
and electrical engineering so that they can build shafts, fill it with
clean air, and select mining machines.
Mining and metallurgical engineers have made steam hammers, Bessemer Processers
for making steel, and have worked on Project Mohole, a hole dug through
the Earth's crust.

Chemical
Engineers
Chemical engineers make things such as plastics, explosives, paint, soap,
etc. They know about the chemical process that changes raw materials
into products we can use. They must know how to control the chemicals and
move them from place to place in the production process. They must know
about things like evaporation, heat problems, about the chemicals, etc.
Chemical engineers have made rubber, the first large Gas Lights System,
Aniline, and Sulfuric Acid.

Electrical
Engineers
Electrical engineers deal with the use, amount, distribution, and production
of electricity. They also design equipment to generate and distribute electricity.
Electrical engineers have created things such as electric street railways,
televisions, cameras, radios, and cables.
