Which is not part of a scientific experiment? Verification Independent Variable Control Dependent Variable 3.

The ones the video showed were: Dimples on a car, dogs afraid of cats, a rock throw at a train, running in the snow Dimples on a car, elephants afraid of mice, a rock being thrown from a lawn mower, running in the rain Dimples of a car, elephants afraid of dogs, a basketball game, running in the rain Dimples on a person, elephants afraid of mice, a rock thrown from a lawn mower, running in the snow 6. What is the definition of dependent variable? the variable changed by the investigator or Scientist the variable that is being measured observed (data) the variable that is not changed, stays the same 7. In an experiment what you keep the same, or constant, is the independent variable dependent variable controlled variable 8. What is the definition of an independent variable? the variable that is changed by the investigator or Scientist the variable that is being measured or observed (data) the variable that is not changed, stays the same jigsaw puzzle (20 pieces) Go to the link and complete the puzzle.
