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

Which answer (or answers) best describes criteria?

• how the model could fail

• the limits of the model

• To make charts and graphs
• To find solutions to problems

You begin to create a prototype of your design only to find that your solution isn't working at all. What should you do?

• Add more tape

• Go back to an earlier stage and choose another solution

• Blame your partner

• Keep going and hope it will be ok

• solution

• design

• prototype

• failure point

The engineering process begins

• when you brainstorm new ideas 
• creating an advertisment
• identifying the need or solution to a problem

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
