If you go to the moon, what will change, your weight or mass? Explain.

Your weight doesn't change.
Your mass depends on how much matter you are made of. This doesn't change when you go elsewhere. Your weight depends on your mass and the mass of the planet/moon/whatever you are standing on. So this can change

Mass will always stay the same no matter where you are in the universe. The equation f=ma shows this.
f is force or weight
m is mass
a is acceleration or the force of gravity
If you ever saw video of men on the moon, you noticed that they were able to jump higher that they would on earth. This was possible because they weighed less than they did on earth. Their muscles were stronger than they needed to be because of their time on earth. On the moon, the force of gravity is much smaller than on earth, so they weighed less.
Another way to explain this is:
Your body is made up of millions of cells. These cells are made up of billions of atoms. Each atom has a specific mass associated with it (look at what is called the Periodic Table of Elements). When you go to the moon, the total number of cells and atoms in your body doesn't increase or decrease. So, the mass of your body must stay the same. Based on the equation above, since the mass stays the same and the force of the moon's gravity is already known, then the only thing that could change is the weight of the person standing on the moon.
on a side note:
On earth, a=9.8 meters per second
On the moon, a-1.6 meters per second

If you go to the moon your weight will change. Mass is consistent wherever you go in the universe. However, weight changes because weight is the force of gravity on a given mass. To further prove what changes lets look at this mathematically. Like I previously stated mass is always consistent, but weight changes. The weight of a mass on earth will be a set amount that this is on the moon because the earth (9.8 N/kg) has a different gravitational field strength than the moon (1.6 N/kg). On earth the weight of a given mass of 10 kg will be:
Weight = mg
= 10(9.8)
= 98 N
On the moon the weight will be:
Weight = mg
= 10 (1.6)
= 16N
So you can see on the moon your weight will decrease but your mass will stay the same.

Your mass always stays constant, unless you were to lose an arm. Your weight changes due to gravity. The moon has much less gravity than Earth, hence the jumping you do there. This means that although your mass is the same you weigh less because not as much gravity is pulling you down.

Your weight changes, it will be about one sixth that of your earth weight. Your mass is always constant unless you overdo the speeding and get close to light speed, which you don't.
Say you weigh 100 kilograms on earth. Because we live on earth, 100 kg is also your mass.
On the moon you'd only weigh 16.6 kg, which is nice for jumping.
But if you'd run and don't get a corner and smack into a wall, you'd hit that wall with the same force as on the earth, because you'd hit it with 100 kg mass. No gravity involved here.

I think it depends on what you eat on the trip. Remember, it takes a week or two to get there, and you aren't working out on your nautilus machine or anything. If you take a lot of dougnuts and like that, you could definitely gain mass. Of course, it is very unlikely that your weight would stay the same, even if you stuffed yourself, since your weight on the moon will be about 1/4 of what you would weigh at that instant on earth.

You will weigh less, but your mass will remain the same. Mass is a measure of how much matter an object has, whereas weight is how hard gravity pulls on you.

mass stays constant; weight changes with the gravity of the planet.
w= g x mass

your gravity will change and a lot of feelings and you will weight less but your mass will remain the same and if you want to learn more stay with me: stephanie beltran

Your mass never changes by definition of mass.

Your MASS will change because no matter where you go, even the moon your weight will not change.
