If you want to develop a new invention, you look up information about it to help you get started. You are

• Asking a question

• Doing Research

• Planning a Prototype

• Testing a Prototype

Engineers must consider many factors such as cost, time, and materials when designing a new invention. These factors are called

• prototypes

• boundaries
• safety

• constraints

What is the final step in the design process?

• Testing
• Select an Approach

• Build a Prototype

• Share the design solution

The first step of the design process is

• Brainstorm/Imagine Ideas

• Identify the problem or need
• Testing the product
• Finalizing the design

How many times should you go through the steps in the engineering design process before you are finished?

• As many times as needed
• Twice
• Once
• 10 times

If you want to build a new type of invention, the first thing you should do is

• Skip research and start building immediately
• Ask someone else to come up with ideas
• Research and identify design specs and contraints

• Copy someone else's invention

A model of an invention is called a

• prototype
• blueprint
• sample
• mockup

Why do engineers test and retest their designs?

• To improve designs

• To save time and resources
• To confuse competitors
• To experiment with different colors

The main goal of the design process is to find solutions to problems.

• True

• False

Engineers redesign their product when they find flaws.

• True

• False
