Early Engineering

Which of the steps listed is performed LAST in the engineering design process?

Choose the correct answer.

• Identify the problem or need.

• Determine the constraints and criteria for the solution.

• Implement the tested and optimized design on a broad scale.

A group of scientists is developing a small, working model of a solar-powered heating and cooling system. What is the purpose of building this model?

Choose the correct answer.

• to make sure the model can fit into small spaces

• to produce a working prototype for customers to use

• to test how changes in one part of the system affect other parts

• to ensure that all of the originally planned features remain the same

Students are asked to conduct two investigations. The first investigation uses scientific practices to find out how birds glide in the air. The second investigation uses engineering practices to design a plane that would glide easily in the air.

Select the practices that would be used only in the second investigation. (Hint: There are 3)

• Use a model to make a prediction.

• Use a model to test a solution to a problem.

• Ask questions and seek answers in a systematic way.

• Define a problem and look for a solution in a systematic way.

• Clearly define a need and the criteria or constraints for the solution.
