Let me say it now…if you don’t put the labels on your answers…
![Page 3: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/3.jpg)
Mass: A measurement of the amount of matter in
an object
It can be measured with a triple beam balance
It is measured in grams.

Volume: Is the amount of space an object takes up.
There are several ways to calculate volume. We are going to look at
the ruler method and the water displacement method.
![Page 5: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/5.jpg)
Just a quick reminder…we only measure in the metric system in this class!!!
So how do we find the volume of an
object using a ruler?
![Page 6: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/6.jpg)
If you said Length X Width X Height…you are ahead of the curve!
Length
Width
Height
![Page 7: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/7.jpg)
L x W x H. ( We use this method when the object has a regular
shape.)
Length
Width
Height
![Page 8: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/8.jpg)
So our formula looks like this:
L x W x H
Length = 4Widt
h =
3
Height = 2
What is our answer?
![Page 9: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/9.jpg)
If you said only 24 you would be wrong…why?
Length = 4Widt
h =
3
Height = 2
![Page 10: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/10.jpg)
So what is the label we use?
Length = 4Widt
h =
3
Height = 2
Centimeters cubed = written like this cm 3

How many of you have every gotten into the tub only to find out you have filled it too high and water
flows over the top?
![Page 12: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/12.jpg)
So what is water displacement?
![Page 13: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/13.jpg)
How does it work?
![Page 14: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/14.jpg)
Just like when you got into the tub, the water level had to go up in
proportion to the amount of space you were
taking up.
![Page 15: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/15.jpg)
What type of objects are you going to use water displacement on?
![Page 16: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/16.jpg)
So would be the first step?
![Page 17: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/17.jpg)
Place a known amount of water into the graduated
cylinder
How much water is in this graduated cylinder?
![Page 18: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/18.jpg)
Read your graduated cylinder carefully…
remember to record your unit of measurement.
![Page 19: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/19.jpg)
Very carefully place your object into the graduated cylinder…what are some
things you need to be aware of as you place the object into the graduated
cylinder?
![Page 20: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/20.jpg)
• Don’t drop it directly into the graduated cylinder – tilt the cylinder to the side and slide it to the bottom…GENTLY
•Only place enough water in the graduated cylinder to cover the object by several mL.
![Page 21: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/21.jpg)
After placing the object carefully in the
graduated cylinder, what should you do
now?
![Page 22: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/22.jpg)
Read the volume of the water after the object has
been put in, then…
![Page 23: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/23.jpg)
subtract your beginning water level from you ending water level.
25 mL20 mL5 mL
Ending Water Level
-Beginning Water Level
Volume of the object

Now what is the unit of measurement we will be using with our
answer.
![Page 25: Mass and Volume of Matter](https://reader036.fdocuments.in/reader036/viewer/2022062503/58ac2c7c1a28abf03a8b6b49/html5/thumbnails/25.jpg)
What is the
volume of this
object?3 mL
