​Water Displacement Method

• ​Step 1: Fill a graduated cylinder... record the volume as your initial, or starting volume.

• ​Step 2: Place the irregular object into the graduated cylinder. The water level will change.

• ​Step 3: Record the final volume.

• ​Step 4: Object volume = final volume - initial volume

Multiple Choice

What unit will you use for your initial volume? 

• mL (milliliters)

• L (Liters)

• cm (centimeters)

• g (grams)

Multiple Choice

What unit will you use for your final volume? 

• mL (milliliters)

• L (Liters)

• cm (centimeters)

• g (grams)

Multiple Choice

Which equation do you use to determine the volume of an irregular object?

• Volume = length x width x height

• Object Volume = Final volume - Initial Volume

• Density = mass/volume

• Length + Mass = Frequency

Multiple Choice

What unit will you use for your object volume? 

• mL³ (milliliters³)

• L (Liters)

• cm³ (centimeters³)

• g (grams)

​Determining Mass of an Object

​To find the mass of an object we use a trible beam balance scale.
