Isolating a Variable in an Experiment

What is one of the steps in the engineering process mentioned in the video?

• Building prototypes

• Variable isolation

• Problem identification

• Testing proposed solutions

What was the initial problem in the slingshot example?

• Throwing a ball into a basket

• Knocking down a pile of marshmallows

• Hitting a target with an arrow

• Knocking down a tower of blocks

Why is it important to change only one variable at a time in tests?

• To save time

• To identify which variable affects the outcome

• To reduce costs

• To make the experiment more complex

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

• The weight of the ball

• The speed of the throw

• The angle of the throw

• The color of the ball

What solution was found to keep the speed of the bowling ball constant?

• Adjusting the bowling lane

• Changing the ball after each throw

• Having friends throw the ball

• Using a ball ramp
