25. 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

37. Based on the notebook entry below, which experiment to test force is likely to have been tested:
In science class we tested the effects of force on objects. I learned that when a force is applied, an equal but opposite force is created. The coach let us borrow materials and we completed the experiment in the gym. The other team won when they crossed the line. Our team fell down to the ground. Learning about forces was fun!

38. A marble is rolled in a straight line inside a box. When the marble gets to the end of the box, it changes direction and rolls the other way. Which statement best describes why this happens?
A. The marble had nowhere else to go, so it moved in the opposite direction.B. The force of gravity on the box pushed the marble in the opposite direction.C. The force of the marble hitting the box produced an opposite force pushing the marble in the opposite direction.D. The marble stopped by the wall and then magnetic force pushed it in the opposite direction.
