Mass and Volume

This slide will tell you step-by-step procedures for finding the mass (or volume) of objects found in every day life.

2. MASS (Definition) Mass - The amount of matter in an object Mass is in every object known to man. It shows how much matter is in an object, and also shows how much space a certain object takes up. However, this is not the same as weight. Weight is the amount of gravitational pull on an object. That is why you would be 100 pounds on Earth and around 30 pounds on the moon.

3. MASS (Ways to Calculate) There are two different ways to calculate the mass in an object. The first way is to weigh it on a balance scale. The way to do this is to set the object on one side of the balance scale, and set weights on the other side till the scale evens out. That will give you the approximate weight of your object. However, this way to calculate mass is not very reliable, as the scale can become unbalanced quite easily.

4. MASS (Ways to Calculate C.) The second way to calculate mass is to set it on an electric mass scale. This way is more easily understood. Just turn on the scale, set the mode to grams, and set the object onto the weigh scale. This will give you a more accurate weight than the balance scale.

5. VOLUME (Definition) Volume - The amount of matter a three dimensional object can contain or hold. Volume can most commonly be found when involving cardboard boxes. You need to know how much the box can hold, especially when you are moving to a new home. You can find volume in every day life.

6. VOLUME (Ways to Calculate) There are two different ways to calculate the volume of an object. This way describes the way to find the volume of a rectangular object. First, you measure the length of the object in centimeters. Then you measure the width and height of the object in the same manner. Then take all your measurements and multiply them together. This will give you the complete volume of the object.

7. VOLUME (Ways to Calculate C.) The second way to calculate the volume of a small object is to put the object in a graduated cylinder. This gets a little complicated, so follow each step carefully. First, fill the graduated cylinder to any mark on it with water. Make sure it is right on and measured to the meniscus. Then drop the small object into the water and calculate how high the water travels. That will be the approximate volume of your object.
