- [Professor Byhower] Okay, this video
demonstrates the part B
section of your manual,
page 143, on observations
of a block of wood.
Okay, so the first thing you need to know
is if you can get these parts
yourself, these materials,
you should do it yourself
and I think you'll learn a lot more.
You have a block of wood,
you have a measuring tape
that has both inches and
centimeters on the other side,
oops, this side has centimeters.
And then you want a measuring cup
that has both the English system,
which is cups, ounces, quarts,
and then, on the other side,
they have the metric system,
which is liters and milliliters.
So to get started,
the first thing they want you to do
is to measure the perimeter of the block,
and that's done simply by taking your tape
and wrapping it around it like I just did.
And then to take a reading from there.
Now, for the *oops* ENGLISH side,
you're going to be reading
right about there, okay?
Right where my thumb is.
And then, on the other side,
you're gonna flip it over
and read the bottom row,
which is the centimeter side,
and let me see if I can
get it on there right.
Okay, so hopefully you can see that.
I'll try to take a picture of that later.
Okay, so that's the perimeter,
it's measured, and that's for distance,
it's measured in
centimeters and in inches.
Now they want you to take
the volume of your block,
and you can do this by
following the directions.
It says to fill your cup first,
or your measuring cup,
with 500 ml's of water,
which I have done.
And then take your block,
and instead of using a wire,
I used a kebab stick,
and you just place it in there.
So we went from 500 to 675, okay?
675, so your new volume
is 675 milliliters.
Then you're going to change
to the English system,
and then they ask you to
go up to the 20 ounce,
so I'm gonna go fill that up
with 20 ounces of water,
up to 20 ounces.
Take my block again,
stick it in there,
and my new volume is 22 ounces.
Okay, so you've got the
mass and the perimeter,
and the last thing they want you to do,
you're going to take
the weight of the block,
but you're going to do that
by watching the video that I showed you
and then reading it off the little file.
So the next part,
you're going to fill your measuring cup
up to four cups,
which, of course,
is equal to one ml, sorry,
which is equal to one quart.
Okay, I have enough water,
okay, so I'm gonna keep pouring
until I get it to the four cup mark,
which is right there, oops.
Okay, right there.
And now I'm simply going
to turn the cup around
and read how many ml's are in one quart.
Because on one side it's a quart
and on the other side it's a liter.
On this side,
it says 950, okay?
So 950 for your volume
for the amount of milliliters in a quart.
You can also do this by doing a conversion
using the table that's on page 143.
Okay, that's it,
thanks for watching.
