A science class is planning an investigation to study the effect of gravity on objects of different masses. Which of the following steps should they take to gather data for their investigation?
Measure the temperature of objects of different masses as they sit on a table.
Drop objects of different masses from the same height and time how long it takes for each to reach the ground.
Listen to the sounds different objects make when dropped to determine the effect of gravity.
Compare the color of objects of different masses to see if there is a pattern.
