What is engineering?

• A type of investigation that uses the scientific method

• A branch of science that is dedicated to studying living things

• A branch of science that deals with designing and building solutions to problems

• A summary or collection of data from primary research studies

What is the engineer design process?

• A process of identifying variables

• A way to solve problems

• A step-by-step procedure to conducting a controlled experiment

• The process of forming a scientific theory

When should you stop testing, revising, and retesting your prototype?

• When you get tired

• When you are satisfied with the final result

• When you cannot make the prototype any better

• Either when you are satisfied with the final result or when you cannot make the prototype any better

What should you do to best understand the problem?

• Ask who, what and why the problem exists

• Research the problem

• Determine whether it's feasible or realistic to solve the problem

• All of the above

What is a model?

• An important variable to designing a solution to a problem

• A representation of something in nature

• A scientific argument against a well-established theory

• A form of creative brainstorming

Why are models useful?

• They help you visualize things that are too small to be seen or too large to be comprehended

• They help you better understand processes that you are studying

• They help engineers design solutions to problems

• All of the above
