5. Engineers design a plan and then test a prototype. Their data show that the prototype is not working. What will the engineers do next?

• communicate their results
• start from the beginning
• improve the design and test it again

6. What problem did cellular phones solve?

• Being able to have something to hold
• Being able to yell at people long distance
• Making it easier to talk to others far away
• Being able to play games while waiting in line

7. Scientists created a car that could run on banana peels. When they tried to drive it, it made loud and weird noises. What step would the scientists need to do next?

• Redesign the prototype and test it again
• Communicate your results and offer it for sale

8. What problem does expanding a road solve?

• Cause accidents
• Make sure people need to replace their tires more often
• Allow for more cars to drive on the road
• Limit the number of cars of the road

9. Miss Feeser designed a microwave that fits into the car, and you can take on road trips. She tested her prototype and redesigned it. The microwave now works perfectly in her car. What is her next step?

• Find a solution to a problem
• Share her design with others and communicate with others
• Redesign it again
• Plan and build a prototype

10. Which is a good way for Miss Feeser to communicate her results of the microwave she created for her car ?

• write an opinion piece on a blog about her prototype
• TikTok or YouTube video about her prototype
• bring her prototype to school
• share using graphs, tables, drawings of her prototype
