PART 1 DIRECTIONS: PLEASE FILL IN THE BLANKS TO COMPLETE THE
PARAGRAPH.
Density
is the _________________ per unit ____________ of an object. The density of an object will remain the
________________, regardless of the size of the object. Density is an important property, because it
allows you to _____________ different types of matter. No two types of matter will have the
________________ density.
The density of water is _________________. If an object has a density that is greater than water, it will _______________ when placed in water. If the object’s density is less, it will _____________ when placed in water.

1. Mrs.
Anderson’s secret identity is Super Anderson, protector of all that is good and
sweet. Her archenemy is the Evil
Mahlum-in-ator. The Evil Mahlum-in-ator
is yucky!!!! One day while working in
her lab, Super Anderson discovers a new metal.
She names the metal “Pinkonium.” When
measured, Pinkonium has a volume of 23.8 cm3 and a mass of 241.75g. What is its density?
2. Super
Anderson realizes that the Evil Mahlum-in-ator hates all that is pink. She begins to form a plan that will rid the
world of his evil presence. Super
Anderson decides to bring her sample of Pinkonium to the evil city of
Evilopolis, where the Evil Mahlum-in-ator lives. To reach the city, she must travel through
the White Pine Forest of Purity in her invisible jet. What is the density of white pine if 6.7 g
has a volume of 63.8 cm3?
3. 
Once Super Anderson nears
the evil city of Evilopolis, she changes into her pink SCUBA gear. She leaps from her invisible plane into the
lake that surrounds the evil city. Her
buoyancy vest is inflated with air and has a mass of 75.0g and a volume of 2.00
mL. Will she float or sink in the water?
4. 
Unbeknownst to Super
Anderson, the Evil Mahlum-in-ator has somehow heard that Super Anderson was
planning an attack! Just as she emerges
from the water, the Evil One drops a Metallica bomb on Super Anderson! Stunned by the blow, she stumbles back. Quickly, she pulls out the Pinkonium and
tosses it at the Evil One. Kindness and
sweetness gas fills the air. If the
gas has a density of 25.0 g/mL and a mass of 100.0 g, what is the volume of the
gas?
Evil Mahlum- in-ator
5. The Evil Mahlum-in-ator
inhales the pink fumes from the Pinkonium and starts to...believe it or
not...smile and act nice!!!!!!! Super
Anderson quickly captures the now defenseless Evil One and places him in her
invisible jet. Together, they fly back
to Super Anderson’s secret Hideout, the Super Cave where the Evil
Mahlum-in-ator will become her slave.
(As her prisoner, he will be forced to do things like dress in pink,
play country music, and put clip art and pretty font on homework assignments
for his students!) If the invisible
jet has a density of 0.00130 g/cm3 and a volume of 40,000.0 cm3,
what is the mass of the jet?
Yes, boys and girls...all seems to be well in the fair city of Menomonee
Falls-opolis. But, on the invisible jet
the kindness and sweetness gas has started to wear off! Oh no!
The Evil Mahlum-in-ator starts to laugh evilly as he yells
“Beware Super Anderson! I shall have my revenge!”
Will he have revenge? Or will he be Super Anderson’s prisoner
forever?
Tune in next time to find out!
