My answers would be as follows:

You step on the scale and notice that you have lost five pounds. Which of the following has changed?


B) Only your weight changed since mass is conserved. It cannot be destroyed or created.


How could you increase the mass of a wooden block?

D) None of the above. Mass cannot be created so the mass will stay the same it will only be the weight you can increase depending on the acceleration.


If you went to the moon, how would your mass change relative to your mass on Earth?

A) It would be the same on the moon as on Earth. Mass will be the same. It is weight that will change since the gravitational acceleration in the moon is different as that to the earth.
