Izzy rolled a marble down a ramp and timed how long it took for the marble to reach the bottom of the ramp. After three trials, she doubled the height of the ramp (making it steeper) and added a thick layer of cotton cloth to the surface of the ramp. She conducted three more trials and after reviewing the data, Izzy concluded that the height of the ramp had no effect on the speed of the marble rolling down the slope.
Which of the following reasons best describes why her conclusion is unsupported?
Izzy miscalculated the speed of the marble.
More trials were needed during the investigation.
A control should have been used in the investigation.
Too many variables were changed during the investigation.
Adrian wants to determine the effect of color on the temperature of the air inside of different colored boxes.
