Science -Unit 1: Lesson 1 (Part 3)

Which step in the design process involves creating a model?

• Define a Problem
• Plan and Build
• Test and Improve
• Redesign

During which step do engineers identify what the problem is?

• Plan and Build
• Test and Improve
• Define a Problem
• Communicate

What should you do if the design does not work well during testing?

• Abandon the project
• Redesign and improve the solution
• Ignore the problem
• Start a completely new project

True or False: Testing is an important part of the design process because it shows if the design works.

• True
• False

True or False: Once a problem is defined, engineers skip directly to communicating their results.

• True
• False

True or False: Engineers might need to redesign a solution more than once to make it work properly.

• True
• False

What is the final step of the design process?

• Plan and Build
• Test and Improve
• Communicate
• Redesign

Emma used a ramp to help her dad move a box. What step is she on when she tells others how she did it?

• Define a Problem
• Communicate
• Test and Improve
• Plan and Build

Why do engineers share their design results with others?

• To show off their work
• To get feedback and improve
• To keep their ideas secret
• To skip the testing phase

True or False: Communicating results is not necessary if the design works perfectly.

• True
• False
