- 12. Multiple ChoiceSimon wanted to know if the height of a ramp affected how fast the car went down it. What part of this experiment is Simon's INDEPENDENT (Test) Variable?height of the rampthe type of carthe speed of the carthere isn't one
- 13. Multiple ChoiceSimon wanted to know if the height of a ramp affected how fast the car went down it. What part of this experiment is Simon's Dependent (Outcome) Variable?there isn't onethe height of the rampthe type of carthe speed of the car
- 14. Multiple ChoiceAfter Simon conducted his experiment he analyzed his data and saw some speeds that were surprising. Why would it be a good idea for Simon to ask his friends to replicate (redo) his experiment?They can test many more different variables that he didthey can compare their results to Simon's to see if he was accurateSo they can get better resultsThey wouldn't do that, scientists do repeat other scientists experiments.
