1. Volume Notes
And a flow chart

2. Define Volume Volume is the amount of space an object takes up or…
Volume is the amount of material a container can hold
Example: this bottle can hold 1 Liter of H2O

3. What is the base unit for finding Volume?
-Remember the base unit for finding volume is Liter
-The abbreviation for Liter is an uppercase L
-The two most common volume measurements are mL and L
-Remember that 1 L is the same as 1000 mL

4. Liquids
To measure volumes smaller than a liter, scientist use the milliliter (mL).
There are approximately 20 drops of water in 1 mL.
Remember: there are mL in a single Liter.

5. What Tools do we use to find volume?
What if we are finding the volume of a liquid… what tool do we use?
Liquids use a graduated cylinder
A graduated cylinder is usually calibrated in milliliters.
Each line on a graduated cylinder is one milliliter.

6. What about rectangular prisms?
To get the volume right we multiply what?
Length x width x height
Why do we use cm3?

7. What is displacement and how do we use it to find volume?
Displacement is the difference in water level (volume) due to the addition of another material

Is it a liquid or a solid?
Are you finding the volume of a LIQUID
Are you finding the volume of a SOLID

10. Are you finding the volume of a LIQUID
What tool would you use?
Are you finding the volume of a LIQUID
Directions for tool:
A Graduated Cylinder finds the volume of liquids.
It measures liquids in mL.
Pour liquid into graduated cylinder
Get eye level with the meniscus of the liquid.
As accurately as possible determine where the bottom of the meniscus is to find your volume
Remember to use the correct units (ex: 13 mL)

15. Rectangle: L x W x H A ruler Directions for tool:
Line the item right on the 0 cm line.
Find the two numbers it is in between (ex: 8 and 9)
Count how many lines past your object is (ex: 3 lines)
Determine your measurement (ex: 8.3 cm)

18. Fits inside a graduated cylinder
Fill graduated cylinder to a set volume (ex: 200 mL)
Gently place item into graduated cylinder.
Read the new volume (ex: 270 mL)
Find the difference of the before and after (ex: 70 mL)
For solid objects don’t forget to convert from mL to cm3

20. To large for a graduated cylinder
What tool to use and how to use it?
Fill a displacement cup with water right up to the brim, and place it inside a tray or other container.
Then place your irregular object in the water, and watch the water overflow a graduated cylinder.
The volume of water you collect in the graduated cylinder will be equal to the volume of your object.
