A science class is planning an investigation about gravity and objects on Earth. In three to four sentences, explain the steps the class should take to provide data to help them make a conclusion about the effect of gravity on objects of different masses.

First, the class should gather objects of varying masses to use in their investigation. They should then set up a controlled experiment where they drop each object from the same height and measure the time it takes to fall to the ground. They should repeat this process several times for each object to ensure accuracy. Finally, they should analyze the data collected and look for any patterns or trends to draw a conclusion about the effect of gravity on objects of different masses.
