IV DV Constants Practice 6th grade

Mr. Smith set up an experiment to see how the mass of a ball affects the distance ball rolls off a ramp (cm). Identify the ^{independent variable}.

• Distance traveled by the ball
• Height of the ramp
• Mass of the ball
• The current weather in Florida

Mr. Smith set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp (cm). Identify the dependent variable.

• Distance traveled by the ball
• Height of the ramp
• Mass of the ball
• The current weather in Florida

Mr. Smith set up an experiment to see how the mass of a ball affects the distance ball rolls off a ramp (cm). Identify a possible CONSTANT for this experiment.

• Distance traveled by the ball
• Height of the ramp
• Mass of the ball
• The current weather in Florida

Mr. Smith set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp (cm). Identify a possible CONSTANT for this experiment.

• Distance traveled by the ball
• Height of the ramp
• Mass of the ball
• The current weather in Florida

Mr. Smith set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp (cm). Identify a scientific title to fit this experiment.

• Distance traveled by the ball vs. the Mass of a ball.
• The effect of the Height of the ramp on the distance the ball will roll from a ramp.
• The effect of the Mass of the ball on the distance a ball rolls off of the ramp.
• The current weather in Florida vs. the mass of a ball.

Mr. Smith set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp (cm). Identify the best written testable question to fit this experiment.

• Does the distance a ball travels affect the mass of a ball?
• Does the height of the ramp affect the distance the ball will roll from a ramp?
• Does the mass of the ball affect the distance a ball rolls off of the ramp?
• Does the current weather in Florida affect the distance the ball rolls off of the ramp?

Mr. Smith set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp (cm). Identify the most appropriate hypothesis for this experiment.

• If the mass of the ball increases then the ball will increase its speed.
• If the mass of the ball decreases then the distance the ball rolls will increase.
• If the mass of ball increases then the distance a ball rolls off of the ramp will increase.
• If mass changes then distance will change. 

A student wants to test the effects of different types of exercise on heart rate.  What is the dependent variable?

• heart rate
• type of exercise
• amount of exercise
• time of day exercise occurs

This variable in an experiment is the one being deliberately changed by the scientist. 

• dependent variable
• independent variable
• data
• control group
