Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes revising the hypothesis. hint: to revise the hypothesis, you use the results of the investigation to come up with a new explanation. ms. conway explained to her science class that objects fall at the same speed even if they have different masses. the class wanted to explore that idea by dropping objects with different masses. the students dropped seven balls, apples, scarves, and pieces of paper out of their classroom window and recorded how long it took each object to reach the ground. the students found that the balls and apples plunged to the ground at similar speeds, but the scarves and paper got caught in the wind and drifted to the ground at slower speeds. the students concluded that objects of different masses don’t always fall at the same speed. they thought that shape affects how quickly an object falls, and that objects of the same shape will fall to the ground at the same speed even if they have different masses.

Explanation:

The students first tested the idea that objects of different masses fall at the same speed. After observing that some objects (scarves and paper) fell differently due to wind - resistance, they used these results to form a new explanation. They concluded that shape affects falling speed and that objects of the same shape with different masses will fall at the same speed. This is the part where they revised the hypothesis.

Answer:

They thought that shape affects how quickly an object falls, and that objects of the same shape will fall to the ground at the same speed even if they have different masses.
