Unit 2 Lesson 2 Lesson Check/Roundup review

Defining a problem is often the first part of the engineering design processes. Which of these steps are usually part of defining the problem? Select all that apply.

• evaluating the design

• doing additional research

• finding a problem to be solved

• testing a solution

Which of these items are known as criteria?

• time

• erosion is reduced

• location

• the solution is safe

• money

Which of these items are known as constraints?

• time

• erosion is reduced

• location

• the solution is safe

• money

Which of the following are true about the engineering design process? Select all that apply.

• Collaboration and communication never play a role in the design process

• Some solutions work better than others

• Each step needs to be followed in an exact order

• The steps are always the same, no matter what the problem.

• Sometimes steps are repeated or blend together.

Why is communication important in the engineering process?

• Engineers want to know what mistakes others have made

• To share information about different discoveries

• To ensure that brainstorming happens after the experiment is designed

• Engineers need it to keep track of where others are living

What should we do after a problem has been identified?

• It is important to add more to the problem

• It is important to do background research to learn more about the problem

• Leave the problem alone

After doing background research and learning about the problem, this will lead to more complete set of _______ and _______?

• designs

• engineering and scientists

• problem and solutions

• criteria and constraints

What role does research play in the design solution process?

• Background research is an important part of the design solution process

• Learning more about the topic helps to ensure that the problem is understood

• Learning more about the topic helps to ensure that criteria and constraints are identified for a good solution

• all of the above
