• hypothetical questions
• leading questions

Engineers use a series of steps known as the _____

• met our criteria
• was the easiest

A condition or a value that can be changed is called _____

• a problem

• a problem we can't solve
• a variable we can change
• a variable we can't change

When dropping a ball, the kind of ball we drop ball is _____

• a problem we can solve
• a problem we can't solve
• a variable we can change
• a variable we can't change

When dropping a ball, one thing we can't change is _____

• the height from which we drop the ball
• the kind of ball we drop
• the gravity that pulls on the ball
• the time at which we let go of the ball

When trying to traverse the gorge, one variable we can change is _____

• the weight of our hang glider
• the speed of the wind
• the distance across the gorge
• the depth of the canyon

When trying to hang glide across the canyon, one variable we can't control is _____
