Which of the following includes reasoning?

• We took two pictures. One had yellow leaves and the one on the windowsill had green leaves.

• Our plant on the windowsill grew more and was green. I know that plants need sunlight to grow, so the green color might have something to do with getting the light they need.

• Our plant in the closet is yellow. The plant on the window sill is growing. They are different colors.

Air is matter. We found that the weight of the ball increases by 0.5 lbs each time we pumped more air into it. This shows that air has weight, one of the characteristics of matter.

Which sentence is the reasoning?

• Air is matter.

• We found that the weight of the ball increases by 0.5 lbs each time we pumped more air into it

• This shows that air has weight, one of the characteristics of matter.

Which sentence is the evidence?

• Air is matter.

• We found that the weight of the ball increases by .05lbs each time we pumped more air into it.

• This shows that air has weight, one of the characteristics of matter.

Question being investigated: Does an object’s mass affect how quickly it falls?

Mass does not affect how quickly an object falls. 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. Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.

What is the evidence?

• No, mass does not affect how quickly an object falls

• 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.

• Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.
