What is the first step in the design process?

• do research

• develop possible solutions

• identify the problem

• test a prototype

Telephones, steam engines, and washing machines are all examples of technology. What do these three examples have in common?

• They help people communicate.

• They solve problems.

• They are used in homes.

• They were recently developed.

Orville and Wilbur Wright used the design process as they designed their airplanes. One of the things they did was to read about other people’s experiments. Which step of the design process is this?

• Doing research

• Choosing one solution

• Identifying the problem

• Communicating results

An engineer wants to design an electric car. She chooses one solution to build. What should she do next?

• create a prototype of the design

• start selling the electric car

• redesign the electric car.

• determine if people like the design
