FLOAT OR SINK?

1.Calculate mass

2.Calculate volume

* Using formula

* By submerging the object in water

3.Find out density

4.Compare with water density

Volume of a cylinder

FLOAT OR SINK?

Calculate the volume by submerging it in water :

1. Fill up the graduated beaker about half way with water.

2. Write down the measurement

3. Submerge the object

4. Take the new measurement.

5. Subtract the new measurement from the original. The difference, is the volume of the object.
