CCK Engineering Concepts and Processes

What is the main job of an engineer?

• To draw pictures for books.

• To design and build things to solve problems.

• To teach science in schools.

• To write stories about inventions.

What is the first step an engineer takes when trying to solve a problem?

• Build a prototype.

• Test their solution.

• Define the problem.

• Do research.

What is a telegraph?

• A type of early radio.

• A system for sending messages using smoke signals.

• An old-fashioned system for sending messages over electrical wires.

• A device for listening to music.

What was the main problem Alexander Graham Bell wanted to solve?

• People couldn't travel far enough.

• Sending messages over long distances was too slow and costly.

• There were no good ways to write letters.

• People needed more entertainment.

Why is "doing research" an important step in the engineering process?

• It helps engineers find out what problems other people have.

• It helps engineers decide what color their invention should be.

• It helps engineers learn about existing solutions and what information they need.

• It helps engineers draw their designs.

What did Alfred Nobel invent to help miners?

• A new type of lamp.

• A safer explosive called dynamite.

• A special mining cart.

• A stronger pickaxe.

What is the purpose of designing a solution?

• To build the final product right away.

• To draw or sketch what the solution will look like.

• To find out if the solution is too expensive.

• To test the solution with real users.

What is a prototype in the engineering process?

• The final version of an invention.

• A simple model used to test a design.

• A book about famous engineers.

• A type of computer program.

Why is it important for engineers to test their prototypes many times?

• To make sure the prototype is very shiny.

• To see if the design works and to make improvements.

• To show off their work to other engineers.

• To find out how much money they can make.

What is the last step in the engineering process?

• Building the final product.

• Selling the invention.

• Evaluating your solutions.

• Starting a new project.
