DENSITY LAB
DENSITY LAB
In this lab you will measure the density of a regular and irregular object.
What is a regular object?
How could you find its volume?
What is an irregular object?
How could you find its volume?
Write the formula for density
Write the SI unit of density in grams and cubic centimeters.
1. Look at your block of wood. Is it a regular or irregular object? __________
First find its mass on the grams scale. Write it here: _________(don’t forget units!)
Now measure its length, width, and height in cm. Write those measurements below:
length = ___________ width = ________________ height = __________________
Find the wood block’s volume using the formula: length x width x height = volume
Write the wood block’s volume here: ___________________ (don’t forget your units!)
Now you can find the wood block’s density. Use the formula D = M/V to find the density. Show your work and write the answer below (don’t forget the units!):
2. Now look at your bolt. Is a bolt a regular or irregular object?
________________________
Find its mass on the grams scale. Write it here: _____________(don’t forget units!)
Find its volume by using the water displacement method. What are the units of
volume using this method? ________________
You can convert your units to cm3 since 1 ml = 1 cm3.
Re-write your units of volume in cm3. ___________________
Now find the density of your bolt below.
Show the formula you will use to find density and show your work and the answer!
NOW ANSWER THESE QUESTIONS:
1. Water has a density of 1 g/cm3. Can you explain why wood floats and bolts sink in relation to the density of water?
2. A solid cube has a mass of 3 grams and dimensions length = 3 cm, width = 3 cm and height = 3 cm. What is the cubes density? (Don’t forget to write the units!)
3. A sphere has a mass of 100 pounds (lbs.) and a radius of 50 in. Volume of a sphere is
1.33 π r3. What is its density? (Don’t forget to write the units!)
