Chemical engineers use chemistry to bridge the gap between scientific invention and manufactured goods.

Chemical engineers know that there’s more to creating a great product than coming up with a new idea. They figure out how to turn new ideas into products that can be mass-produced.

Whether they’re making perfume with a fragrance that lasts or cookies that taste homemade or tape that sticks in the rain, chemical engineers are using their understanding of chemicals and chemical reactions.

Chemists research chemicals -- the building blocks of all materials. Materials scientists conduct research on the structures and compositions of materials.

You may not realize it, but the products of chemistry play a big role in our daily lives. Chemists and materials scientists create the building blocks for medicines like Prozac or products such as plastic bags. Even the chocolate, marshmallow, and banana flavors of the processed food you eat were created in a lab by food chemists.

Chemists and materials scientists working in applied research come up with new products for industrial, commercial, and medical use.

Environmental engineers use math and science to address environmental challenges such as hazardous waste and pollution. They also study the impact on the environment of proposed construction projects.

Back in 1910, President Theodore Roosevelt stressed the importance of treating our natural resources well. He said that we must pass them on to the next generation improved -- not impaired.

Environmental engineers work toward that goal. They help cities and construction companies find ways to build that don’t damage the environment. They help to clean up environmental problems from the past. They work with factories so they pollute less. Environmental engineers do their part to make sure that the earth will be in good condition for those who live here tomorrow.

Industrial engineers consider factors such as location, inventory, and the needs of workers to create systems that help businesses and other organizations run better.

Suppose you had a great idea for a new product. Even better, suppose a lot of people wanted to buy it. First, congratulations! Second, how are you going to make it? How many workers will you need? How many items can they produce? What kind of system will help them make more? What kinds of parts will they need to make it? How much should you keep on hand?

An industrial engineer can help you answer these questions. Or, if answering questions like these sounds like an interesting challenge, you could become one.

Materials engineers find ways to use and improve existing materials and then come up with new ones. They work with metals, ceramics and glass, plastics, and other natural and synthetic materials.

Did you ever wonder why rubber bands stretch and string doesn’t? Which would help your golf game more, a club with a graphite shaft or one of steel? What makes something waterproof? Would you build a bridge in a cold climate out of the same material as you would in a hot place?

These are the kinds of questions that materials engineers answer. They find -- or make -- the right materials for the job. 

Mining and geological engineers help find deposits of coal, metals, and minerals. They also design mines and mining equipment for bringing these materials to the earth. And they solve safety and environmental problems related to mining.

A lot has changed since the nineteenth century when the forty-niners panned for gold in California. Mining and geological engineers now use satellite photography and variations in the earth’s magnetic field to find new deposits of minerals. They use machines that can remove 10.8 metric tons of coal per minute.

But it’s not just about the tools. Today’s mining pros are also finding ways to mine that are safer for both mine workers and the environment.

Occupational health and safety specialists promote better health and safety in work environments and prevent harm to workers and the general public. They also enforce air quality and environmental regulations.

As an occupational health and safety specialist, your job will be to make sure that working conditions are as safe as possible. You may inspect and enforce safety standards on assembly lines or protect workers against biohazardous waste in hospitals. You may inspect safety standards at nuclear power plants or within public schools.

The job may also require studying, redesigning, and updating working environments. And if an accident occurs, occupational health and safety specialists help investigate possible causes and recommend corrective action.

Petroleum engineers search for oil and gas. They design ways to remove as much as possible from the earth and to turn it into fuel we can use.

The United States gets about 63 percent of its energy from oil and natural gas. That means that there’s a constant race to find new sources of petroleum and natural gas, get them out of the earth, and process them.

Today’s petroleum engineers are using the latest high-tech equipment to do just that. They keep homes heated, cars running, and stoves burning.
