Defining Problems, Criteria, Constraints

The first steps in science and engineering:

• Analyzing and Interpreting Data

• Conducting an Investigation

• Asking questions and Defining problems

• Developing and Using Models

The goal of science is to:

• Explain phenomena / how the world works

• Interpret data

• Fulfill human needs

• To have fun and have do cool experiments

• Hypothesis

• Dependent Variable

• Control Variable

• Independent Variable

This year I set a goal to workout 4 days per week. However, because of social distancing guidelines, I have to wear a mask at the gym now. Since exercising more, I increased my speed on the treadmill. When I inhale deeply, my mask goes into my mouth. This makes exercising more challenging.

WHICH QUESTIONS WOULD AN ENGINEER USE TO DEFINE THE PROBLEM? Select all that apply.

• How can I get out of wearing a mask at the gym?

• Am I going too fast on the treadmill?

• How can I manipulate my existing mask so I can breathe easier?

• Why does the mask go into my mouth?

• What are the existing solutions for this problem?

What questions would these engineers need to answer in order design a solution? Select all that apply.

• What materials are available?

• What is the budget of the design?

• What type of mask are you currently using?

• What type of treadmill are you using?

What questions would an engineer need to answer in order to design a solution? Select all that apply.

• What can be added to existing masks to prevent inhaling while still meeting mask guidelines?

• Do you have to exercise?

• What is the deadline to design a solution?

• Will putting a fan in front of the treadmill make it easier to breathe?

• How can I fix this problem?
