How is communication an important part of designing solutions? Choose all of the statements that are correct.

• Communication helps people talk about improvement.

• Communication helps identify problems.

• Communication only causes arguments.

• Communication creates a sense of teamwork.

• Communication is critical only if everyone agrees.

Choose the correct words to complete each sentence. When building and designing an engineering solution, it is always important to _______________ the solution.

• ignore

• original problem

• multiple times

• once

• test

Good engineers will always try to test a solution _______________.

• ignore

• original problem

• multiple times

• once

• test

It is important to keep in mind the _______________ that the solution was meant to solve when designing and testing a solution.

• ignore

• original problem

• multiple times

• once

• test

Circle the letter of each correct statement.

• Making good observations is important.

• Making good observations helps to figure out what needs to be improved.

• Making good observations shows you what to test next.

• Making good observations is not important because it slows down the process.

• Making good observations can be distracting and should be stopped when it happens.

An engineer is testing a solution. The solution is failing. What should she do? Select all that apply.

• She should consider using other materials for the same design.

• She should figure out what didn’t go right with her design.

• She should understand that sometimes things don’t work as planned.

• She should not try to develop other solutions to this problem.

Feedback is important in solving any problem. Select the best example of how to give good feedback.

• Tell the other person that his or her project is a good example of what not to do.

• Tell the person that his or her design is poorly built. Do not suggest any improvements.

• Tell the person that his or her design is built well but still suggest some possible improvements.

• Ignore the person if he or she isn’t listening to you.

Which of these describes a good approach to solving an engineering problem? Select all that apply.

• Research, revise, and repeat.

• Give up if your first solution fails so that you don’t waste any more of your time.

• Failure marks the end of the process.

• If at first you don’t succeed, try, try again.

An engineering design solution that does not pass testing can be considered a successful solution because:

• It provides valuable insights for improvement.

• It meets all initial design requirements.

• It is cost-effective.

• It is aesthetically pleasing.

Below are steps that you might follow to solve an engineering problem. Add numbers to put them in order.

• 1. Identify the problem that needs solving. 2. Research information about the problem. 3. Identify criteria and constraints. 4. Choose materials for the prototype. 5. Create the prototype. 6. Test the prototype. 7. Perform failure analysis. 8. Improve prototype. 9. Test final design.
