A Case of "What-Ifs"

What kind of questions do engineers ask themselves every day?

• "what if" questions
• closed questions
• hypothetical questions
• leading questions

Engineers use a series of steps known as the _____

• step-by-step process
• manufacturing process
• engineering process
• scientific method

We started by defining a solvable problem, in our case _____

• how can we build a hang glider?
• how can we inflate the balloons?
• how can we use the umbrella?
• how can we get across the gorge?

We looked at more than one solution and chose a solution that _____

• used the balloons
• used the umbrella
• met our criteria
• was the easiest

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

• a problem
• a variable
• a prototype
• a solution

The height from which we drop a 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, 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 _____

• the weight of our hang glider
• the speed of the wind
• the size of the wings
• the angle of the wings
