Designing a Trial

When engineers design a solution to a problem, they focus on _____

• a failure point
• a scale model
• an isolated variable
• a specific outcome

In order to make sure that a solution meets a specific outcome, engineers _____

• identify a single failure point
• isolate a specific variable
• do a bunch of trials
• do a single trial

The criteria are the rules we use to _____

• isolate a variable
• judge a solution
• strengthen a bridge
• step through a problem

Conditions that could change over the course of an experiment are called _____

• criteria
• variables
• failure points
• solutions

When we launched Catbot into a pile of marshmallows, we only changed _____

• the angle of the slingshot
• how hard the slingshot was pulled
• the number of marshmallows
• the distance to the pile

The places where a solution doesn't work anymore are called _____

• variables
• criteria
• failure points
• isolations

Getting a ring around the pin, and doing it in one throw are the _____

• variables we can change
• criteria for success
• variables we can isolate
• problems we can solve

The size of the ring, and the distance we can stand away from the pin are _____

• variables we can change
• variables we can't change
• problems we can solve
• problems we can't solve

In the ring toss game, which variable are we unable to change?

• the size of the ring
• the size of the pin
• how we throw the ring
• the pull of gravity

In the ring toss game, we first chose to isolate _____

• the size of the ring
• the distance from the pin
• the size of the pin
• how we throw the ring
