Engineering Lesson

Engineers use a design process to invent or improve machines. What is the first step in this design process?

• Make a prototype of the design.

• Make a graph to show how well the design worked.

• Keep notes and drawings of the design throughout the process.

• Identify a need or problem to be solved.

A student team designs a device to meet a human need. Then the students build a prototype.

Which of these best describes the purpose of a prototype?

• to develop ideas for a solution

• to show how the design will look

• to test the quality of the conclusions

• to see whether it meets design criteria

Why should engineers test their designs?

• to find ways to improve their designs

• to make them smaller and more compact

• to change the design to be more profitable

• to discover solutions to problems that have not yet occurred

Which is a true statement about the work of engineers and the work of scientists?

• Engineers analyze data, and scientists do not.

• Scientists often work in teams, and engineers do not.

• Both follow a series of steps to find solutions to problems.

Why do scientists follow the design process?

• to find solutions to problems

• to understand how Earth formed

• to practice making measurements

• to use the same solution for every problem.

Engineers designed a machine that will decrease air pollution. What is the main purpose of telling others about this machine?

• to build a prototype

• to gather data about a problem

• to keep people from copying the design

• to help other people solve the same problem

Jason and Luis have designed and tested a tool to help them construct a backyard birdhouse. Now they are writing a summary of their conclusions.

What will these conclusions communicate?

• whether the data reflected the purpose

• whether the prototype met the criteria

• whether the design matched the model

• whether the design process created the data
