Engineering Design Exam

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

What is a problem?

• A controlled variable
• Something that sparks scientific arguments
• A difficulty or need that must be overcome
• A way to improve an experiment

What is brainstorming?

• The process of generating ideas
• The process of communicating scientific ideas
• A type of headache
• A critique of a scientific study

What should you consider when choosing a solution that will best solve a problem?

• The cost
• The benefits and risks
• The feasibility or practicality
• All of the above

What do you call the first or preliminary model of a solution?

• A controlled variable
• A focused solution
• A prototype
• A drawback

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 b and c

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
