How do block of different sizes react to force?B. How do different surfaces affect the amount of force needed to move a block?C. How do blocks affect spring scales?D. How does the mass of a block change when it is pulled across a desk?

50. M.S. ?’s25. 5th graders have been studying force and motion. One group of students decided to repeat Galileo’s famous experiment for their science project. They designed an experiment to test the effects of gravity on heavier objects versus lighter objects. They dropped an iron ball and rubber ball from two flights of stairs. 3 trials runs were conducted and then data was recorded. Why did the students conduct 3 trial runs during the investigation?A. To formulate a hypothesisB. To increase reliability of resultsC. To test more than one variableD. To impress the teacher
