• an evaluation
• a plan
• unknown variables

In the slingshot game, we decided that we could change one of two _____

• variables
• options
• criteria
• angles

When we changed the angle of the slingshot, we also  _____

• pulled a bit less
• pulled a bit harder
• didn't change how hard we pulled

In repeated trials, we should _____

• change only one variable at a time
• pull harder on the slingshot

When you choose one, and only one, variable to change, it's called _____

• dividing a variable
• imprisoning a variable

• variables
• criteria
• options
• conditions

In the bowling game, knocking down the pins and doing it all in one turn were _____

• variables to change
• problems to solve

In the bowling game the mass, the angle, and how hard we threw the ball were _____
