  2. 7. a gauge of how close your data values are to each other
  3. 8. the variable being changed by the scientist
  4. 9. things that are LESS dense than what they are placed in will do this
  5. 11. a gauge of how close your data values are to the accepted value

  1. 2. the variable being measured in an experiment
  2. 3. this term describes an object falling ONLY due to the acceleration of gravity
  3. 4. the variable kept constant in an experiment
  4. 5. if your percent error is this value or less, your results are accurate
