A group of students conducted an investigation to collect data on how much potential energy an object has as it moves farther and farther from Earth's surface. To measure this students dropped a marble from different heights onto clay and measured the crater left by the marble by filling it with drops of water. Their results are shown in the picture. What is the independent variable in this experiment?

• mass of the marble

• height

• drops of water (volume of crater)

• diameter of marble

A group of students conducted an investigation to collect data on how much potential energy an object has as it moves farther and farther from Earth's surface. To measure this students dropped a marble from different heights onto clay and measured the crater left by the marble by filling it with drops of water. Their results are shown in the picture. What is the relationship between the height of the drop and crater depth.

• On average the higher the ball was dropped from the deeper the crater is.

• On average the lower the ball was dropped from the deeper the crater is.

• On average the higher the ball was dropped from the shallower the crater is.

• There is no relationship between release hight and crater depth.
