Reasoning
Mia, Arjun, and David were playing basketball. They noticed that the ball was not bouncing well, so they decided to pump more air into it. They found that the weight of the ball increases by .5lbs each time they pumped more air into it. This is important because it shows that air has weight, one of the characteristics of matter.
Which sentence is the evidence?

Claim
Opinion
What is the reasoning in the following argument...?
In our experiment, the blocks had different masses, 20 g., 30 g., 44 g., 123 g. and 142 g. but the time for all five blocks to fall was about the same. It took between 1.5 and 1.8 seconds for them to fall. No, mass does not affect how quickly an object falls. Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.
