3. Define density?
__________________________________________________________________________
The concept of density is sometimes confusing since it has to do with particles that we cannot
see (atoms and molecules). If a substance is dense, that means that the atoms/molecules
are close together.
Examples: The dots below represent atoms.

4. How many total dots are in example 1? ______ how many in example 2? _______
5. In which example are the dots (atoms) closer together? Example #______
6. Which example shows a greater density? #______
7. Density Equation: Density = ____________________________________________
8. The units for density are ___________________ or __________________.
Calculate the densities of the following objects to the nearest hundredth. Remember to
place units of measurement after each number!
9. Object A
mass = 36g
length = 6cm
volume = _____
width = 3cm
density = _____
height = 1cm
10. Object B
mass = 300g
length = 10cm
volume = _____
width = 5cm
density = _____
height = 2cm
11. Object C
Use the water displacement method to determine the density of
object C (silly putty). Initial water level in graduated cylinder = 25ml. Final water level after
placing silly putty into graduated cylinder = 29ml
mass of silly putty=8g
volume = _____
density = _____
12. Calculate the density of the metal cube listed below. The mass is 8 grams and the
volume is 4 ml. What is the density? Write the problem and answer below.
Mass ________ / volume _________ = density __________
13. Imagine that the cube is split in half exactly. What is the mass of one half of the cube?
______________ . What is the volume of one half of the cube? ______________
Calculate the density for each of the halves. Write the problem and the answer below.
Mass ________ / volume _________ = density __________
14. Does size affect density of a substance? Why or Why not?
