More Details of Density
1) What is density?_______________________________________________________________________________________________________
2) We use ____________________________ and ______________________________ to measure density, so the units of density are
often___________________________________ or ______________________________.
3) The _________________________ the density the _________________________________ something will be and the
_____________________________ the density the _________________________________________ and something will be.
4) ____________________________ and density are different. Two pounds of feathers weighs more than 1 pound of steel
but steal is more dense.
5) Density will determine if something __________________________________ or ____________________________________. Let’s think
about ice. It is _______________________________ dense than water that is why it floats in water The density of
____________________________ is 0.92 g/ml and the density of water is 1.00 g/ml.
Density is a physical property. That means it NEVER CHANGES!!!. A Big piece of lead will have the same density as
a small piece of lead because all lead has the same density.
Big piece of lead-Density =
11.3 g/cm3
Big piece of lead -Density =
11.3 g/cm3
6) Using density we can find other parts of the ______________________________. If we have density and mass we can find
_________________________________________________. That equation is V= mass/ density
7) If we have density and volume we can find _______________________________. That equation is M= Density x Volume.

More Details of Density With Answers
1) What is density? ___Density is an amount of mass for a specific volume______________________
2) We use ________mass____ and ___________volume_______ to measure density, so the units of density are
often ________g/mL_______________ or ________g/cm3____________.
3) The ______higher ____ the density the _______heavier______ something will be and the
________lower_________ the density the ______________lighter_______ and something will be.
4) ______Mass______ and density are different. Two pounds of feathers weighs more than 1 pound of steel but steal is
more dense.
5) Density will determine if something _________will sink_____ or ______________float________. Let’s think
about ice. It is ___________less_____ dense than water that is why it floats in water The density of
_________ice_______ is 0.92 g/ml and the density of water is 1.00 g/ml.
Density is a physical property. That means it NEVER CHANGES!!!. A Big piece of lead will have the same density as
a small piece of lead because all lead has the same density.
Big piece of lead-Density =
11.3 g/cm3
Big piece of lead -Density =

6) Using density we can find other parts of the ______equation_______. If we have density and mass we can find
______________volume__________________. That equation is V= mass/ density
7) If we have density and volume we can find __________mass_____. That equation is M= Density x Volume.
