Used to measure the volume of liquids or irregular shaped objects.

### volume

The amount of space an object takes up.

### meniscus

When water is placed in a graduated cylinder it forms a downward curve. This curve is the meniscus. Always measure at the bottom of the meniscus.

### pipette

A dropper used to adjust the water level in a graduated cylinder.

### Rules for using a graduated cylinder

1) Use a flat level surface. 2) Read the volume at the bottom of the meniscus. 3) Use a pipette to adjust the water level. 4) Make sure you are eye level with the meniscus when reading the water level. 5) Label your answer with ml or mL, don't forget the decimal point and a zero.

### Volume by Difference (Rise Up Method)

A way of finding the volume of an irregular shaped object.

### Step for using the Rise Up Method

1) Make sure the water level is above the height of the object being measured. 2) Record the water level. 3) Put the object in the water. 4) Record the new water level. 5) Subtract to find the volume of the object.
