An engineer has designed and built a prototype to improve the brake system of a car. What is the next step that the engineer should take in the process?

• Test the prototype.
• Make sketches of the prototype.
• Identify constraints.
• Collect and analyze the test results. 

Jacob has noticed that when he opens his bedroom door, the doorknob hits the wall. He decides to design a device to absorb the force of the opening door. He has identified the problem. What is the next step in his design process?

• Evaluate the design.
• Identify the criteria and constraints.
• Brainstorm solutions. 
• Sketch a possible prototype.

What is the first step in the Design Process?

• Identify the Problem
• Construct a Prototype
• Develop Possible Solutions
• Optimize

A small group of people start sharing ideas. Some ideas may seem silly, but all suggestions are written down for further consideration. This activity is part of which step of the Design Process?

• Choose the Best Solution
• Brainstorm Design Solutions
• Research
• Communicate Results

During which step of the Design Process do you experiment with the prototype under controlled conditions and collect /record data?

• Test and Evaluate
• Construct Prototype
• Optimize
• Analyze Results

It is important to sketch detailed drawings/blueprints and ask for feedback. This happens during which step of the Design Process?

• Design Solutions
• Construct Prototype
• Redesign
• Communicate Results

 During which step of the Design Process would the specific constraints or criteria of the problem be identified

• Define
• Design Solutions
• Construct Prototype
• Optimize

 In which step of the Design Process would you discuss questions such as: Has the criteria been met? If so, how well? If not, why not? What are the next steps?

• Identify the Problem
• Optimize
• Design Solutions
• Construct Prototype

Which word best describes a constraint?

• option
• opportunity
• limitation
• goal

A prototype is a model that

• functions like the final solution would
• is made of the same materials as the final product
• is made after the final product is made
• has to be 3D
