Methods for Calculating Density

Calculating Density Remember, Density = mass/volume Mass is determined using a scale Volume is calculated several different ways

Finding Volume To find the volume of a liquid, use a graduated cylinder Make sure to read the bottom of the meniscus

Finding Volume Length x Width x Height Volume of a regular object, such as a wooden block

Finding Volume Water Displacement Method - Read the initial volume of water in a graduated cylinder - Place object into cylinder - Read the final volume of water - Final – Initial = Volume of the object

Density Water Displacement Lab Ms. Ose will assign lab groups

Lab Safety/ Clean Up No closed toe shoes or aprons are required If you spill, clean the water with a paper towel When you finish collecting data, return the lab area as you found it

Density Practice When you finish the lab activity begin working on the Density practice problems. Whatever problems you do not finish will become your homework.
