    1. To use a balance you have to make sure the balance is even on both sides before you start. Then you can put an objects on both sides to see which one weighs more. You can also put an object on one side and gram cubes on the other to figure out how much the object weighs.

    2.To compare two objects you put the objects on opposites sides of the balance. The heavier oject will make the balance go down. The lighter object will go up.

    3. To find the wieght in grams you put the object on one side and gram cubes on the other side. You will add gram cubes until the balance is even. Then you will count all of the gram cubes to see how much the object weighs.

    4. The fulcrum is the middle part of the balance. It is the triangle part of the blue balance in the picture. It is where the balance rocks back and forth.

  2. 1. To measure mass using a balance beam, first you have to put the balance beam together. Next, put one cup on each side and put the object you want to weigh in one cup and the grams in the other. Add or remove grams to the cup until the cups are even. Finally, count how many grams we in the cup.

    2. A falcrum the top point of the balance beam.

  3. 1. First you put some type of object in one of the cups. Then you put the mass pieces in the other cup. Next, you make sure its equal. If its not equal, you have to try some more mass pieces.

    2. To compare two objects I could see if one is heavier than the other one. One way is to lift each in one hand. In the balance beam, I'd put each in a cup and see if its equal. And if its equal or not equal, you'd write it on a piece of paper.

    3. To find the weight of an object in grams, you would have to count the mass pieces which are in grams.

    4. A fulcrum is a point in the balance. Its the part that its balance on. You can't see it, when the other piece is on top.

    1. Yes, I would make sure the beam is leveled. Then I would put one object on one side and the mass pieces on the other side until it was leveled.

    2. I would put one object on one side and the other object on the other side to see which one weiths more and which one weighs less.

    3. I would put the object on one side and add the mass peices that equal grams to the other side until the beam is leveled.

    4. The fulcrum is the tip of the balance.
