##### Presentation Transcript

1. Mass/Volume/Density Sarah Stack andAsh Letts

2. Mass • Mass is a measure of the amount of material in an object. • It can be measured with grams and kilograms. • A large object contains more matter then a small object made of the same material. • To find the mass of an object, you can measure them with a balance or a scale.

3. Examples

4. Volume • Volume is the amount of space an object with matter takes up. • The volume of a solid can be measured in cubic centimeters (cm3) • Liquid volumes are measured in liters (L) or milliliters(mL). • One cm3 equals one milliliter. • To find the volume of a solid that does not float in water, measure the volume of water it moves away while it sinks.

5. Volume is how much space the object takes up (in this case Justin Bieber) !!!

6. Density • The density of an object is its mass per unit volume . • To find the density of an object , measure its mass and its volume then add them up! • After that, divide the mass by the volume or vice versa. • Remember density is not the same as mass.

7. This is an example of a one kg. balloon sinking!

8. Fun Facts • A bottle filled with plastic foam will float because the foam is less dense then the water. • A bottle of sand will sink because sand is denser then water. • All objects of a pure item kept under the same conditions have the same density.

9. THE END • I hope you liked our presentation !!!
