Engineering Process and Variable Isolation Quiz

What is one of the key steps in the engineering process?

• Final product sale

• Testing proposed solutions

• Hypothesis creation

• Marketing analysis

What should engineers change to test their solutions effectively?

• All variables randomly

• Only one variable at a time

• Multiple variables at once

• No variables at all

What does isolating a variable help engineers determine?

• The cost of materials

• Why a solution works or doesn't

• The color of the final product

• The marketing strategy

What happens if multiple variables are changed at once during testing?

• It is impossible to determine the effect of each variable

• It simplifies the test

• It makes the test invalid

• It helps identify the best variable

What was the successful variable change in the slingshot experiment?

• The angle of the slingshot

• The size of the slingshot

• The strength of the pull

• The type of marshmallows

What is the purpose of setting criteria in engineering tests?

• To determine the price

• To judge the success of a solution

• To design the product logo

• To choose the project team

In the bowling experiment, what variable was initially chosen to be isolated?

• The weight of the ball

• The speed of the throw

• The color of the ball

• The angle of the throw

Why was it difficult to maintain the same speed in the bowling experiment?

• The pins were misaligned

• The lane was inconsistent

• Arm fatigue affected the throw

• The ball was defective

Why was using a ball ramp considered in the bowling experiment?

• To make the game harder

• To increase the fun

• To change the ball color

• To keep the throwing speed consistent

What ensures a test's success according to the criteria set by engineers?

• Changing as many variables as possible

• Testing without any plan

• Using the most expensive materials

• Isolating and testing one variable at a time
