VolumeVolume is the amount of space that matter takes up. The volume of something
can be measured using math and a graduated cylinder, a ruler, or a tape measure.
volume = Length X Width X Height
Think about these two methods for calculating a solid’s volume. Which one would be used to find
the volume of...
volume = Length X Width X Height
This method is better because it
is an irregular shape.
This one because it is a nice, straight shape that can easily be
measured with a ruler.
cotton balls white sand
Look at these containers. One is filled with cotton balls and one is filled with white sand.
Do they have the same volume?
Yes!!!!Since both containers are the same size, they both take up the exact same
amount of space, so they have the exact same
volume! With volume, it doesn’t matter how heavy
the matter is!
mashed potatoes rice Krispies
Look at these cups! Compare their mass and their volume.
They both have the same volume because they are both the same container. However, their masses are
different. Mashed potatoes would be heavier
than Rice Krispies!
MassMass is the amount of matter something contains. The mass of something
can be measured using a triple beam balance.
Think about the mass of these objects. Put them in order from least to most in your mind. Then click to check.
cotton balls white sand
Look at these containers. One is filled with cotton balls and one is filled with white sand.
Do they have the same mass?
No!!!!They have the same
volume, but not the same mass. White sand has a lot
more matter than cotton balls, therefore, it is
heavier, and has more mass!
cotton balls white sand
Density compares the volume of something to the mass of something!
Mass: 100 gramsVolume: 136 cubic centimeters
Mass: 200 gramsVolume: 136 cubic centimeters
Density= mass divided by volume!100/136= .74
Density= mass divided by volume!200/136= 1.47
WHITE SAND IS MORE DENSE!!!
mashed potatoes
216 g.
Rice Krispies104 g.
What conclusion could you draw about density from this information? Each measuring cup is filled with a certain food. It’s mass is given.
Chips83 g.
The chips are the least dense. The mashed potatoes
are the most dense, and the Rice
Krispies are in between.
If you wanted to measure the density of these items, which tools would you use?
length X width X height
If you wanted to measure the density of these items, which tools would you use?
length X width X height
If you wanted to measure the density of these items, which tools would you use?
length X width X height
The less dense an object is, the more buoyant it is! Which of these items do you think is buoyant?
Bobbers float on water when you’re fishing!
Wood also floats! That’s
why boats are made of wood!
If I mixed these together, would it be a solution?
NO! You could un-mix it using your hands or a magnet!
If I mixed these together, would it be a solution?
NO! You could un-mix it using your hands or a
filter!
Some things dissolve easily in water!Which ones do you think?
Leaves won’t dissolve.
Sugar dissolves
VERY easily– especially in warm water!
Chocolate will dissolve,
but not as easily as sugar!
Salt will dissolve, but not as easily
as sugar!
I tricked you! Ice doesn’t dissolve, it
melts! Plus, ice is the same thing as water, so
it’s not a different material.
