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.

??

The class should first choose a variety of objects with different masses. They should then measure the weights of each object using a scale. Next, they can drop each object from the same height and measure the time it takes to reach the ground using a stopwatch. By analyzing the data collected, the class can make conclusions about the effect of gravity on objects of different masses.
