Try Trials

The video tutorial uses bowling to illustrate the engineering problem-solving process. It explains how engineers identify variables and criteria to test solutions. By isolating the angle of the ball as a variable, the tutorial demonstrates conducting trials to achieve a strike. The process involves keeping other variables constant and adjusting the angle to meet the criteria of knocking down all pins in one turn. The tutorial concludes by emphasizing the importance of trials in engineering.

What is the first step engineers take when solving a problem, as discussed in the video?

• Ignoring variables

• Changing all variables simultaneously

• Identifying and isolating a variable

• Testing all variables at once

Which variable was chosen to be isolated in the bowling experiment?

• The mass of the ball

• The type of pins

• The speed of the ball

• The angle of the ball

What was the outcome when the ball was aimed directly down the middle of the lane?

• All pins were knocked down

• Some pins were knocked down

• The ball went into the gutter

• The ball stopped halfway

What was the result when the ball was aimed far to the right side of the lane?

• The ball hit the left pins

• Some pins were knocked down

• A strike was achieved

• The ball went into the gutter

What is the significance of conducting multiple trials in engineering problem-solving?

• To ensure the solution is entertaining

• To confuse the problem-solving process

• To test different variables simultaneously

• To verify if the solution meets the criteria
