OBSERVATION 2: Aljune and Toby proposes the idea that the marble would travel at a faster pace if it is rolled down the longer slide. PROBLEM: What happens to the speed of a marble travels when the height of a ramp is changed? HYPOTHESIS: If the height of a ramp is doubled, then the marble will reach the same speed even if the inclined is increased. INDEPENDENT VARIABLE (S) (IV): DEPENDENT VARIABLE(DV): CONTROL VARIABLE (S (CV)):
