• All of Above

How does technology affect your school?

• It makes it harder to get your work finished.

• The public address system allows the principal to communicate with the whole school at the same time.

• It allows the teacher to talk to one student at a time.

• It gives the students time to talk with friends.

Which of the following is NOT a step in the design process?

• Do research

• Construct a prototype

• Identify and control variables.

• Redesign.

Which two reasons might cost affect which prototype you chose to build?

• You would choose a prototype that you think is the coolest.

• You would choose a prototype most people could afford.

• The prototype costs don't matter.

• If the prototype costs too much to build, few people would be able to buy it.

Why do you think engineers build prototypes of their designs?

• They need to see if their friends will like it.

• They like to build models.

• They can use the prototype to test whether or not their design works.

• The prototype helps them answer questions.
