2. Do Now Pick up the new half sheet
Glue it to the fourth page of your journal*
Add this page to your Table of Contents (see marker board on right side of room)
*If you don’t have a journal, get one from Mr. Hallihan, and start setting it up (use a classmate’s as an example)

3. English vs. Metric Units
Which is larger?
A. 1 liter or 1 gallon
B. 1 liter or 1 quart
C. 1 milliliter or 1 fluid ounce
1 fl oz = ml
1 12-oz can of soda would equal approximately 355 ml.
1 gallon = 3.79 liters
It would take approximately 3 ¾ 1-liter bottles to equal a gallon.
1 quart = liters

Metric Units kL cL mL L
Volume is the amount of space an object takes up.
The base unit of volume in the metric system in the liter and is represented by L or l.
Standard: 1 liter is equal to one cubic decimeter
Metric Units
1 liter (L) = 1000 milliliters (mL)
1 milliliter (mL) = 1 cm3 (or cc) = 1 gram*
Which is larger?
Click the image to watch a short video about volume.
A. 1 liter or 1500 milliliters
B. 200 milliliters or 1.2 liters
C. 12 cm3 or 1.2 milliliters*

5. Measuring Volume
We will be using graduated cylinders to find the volume of liquids and other objects.
Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water.
What is the volume of water in the cylinder? _____mL
What causes the meniscus?
A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.

6. Measuring Liquid Volume
What is the volume of water in each cylinder?
Images created at A B C
Pay attention to the scales for each cylinder.

7. Measuring Solid Volume
10 cm
9 cm
8 cm
We can measure the volume of regular object using the formula length x width x height.
_____ X _____ X _____ = _____
We can measure the volume of irregular object using water displacement.
Amount of H2O with object = ______ About of H2O without object = ______ Difference = Volume = ______

8. Volume Lab 1. Fill your graduated cylinders up to 10 mL with water
2. Record this data directly into your science journal:
Estimate how many drops it will take to add one milliliter of water to your graduated cylinder
Use your eye dropper to add water one drop at a time until the level raises to 11 mL
How many drops did it actually take?

9. Volume Lab 1. Fill your graduated cylinder up to 20mL
2. Carefully drop your three marbles into the graduated cylinder.
3. How much did the water level rise? (Subtract 20 from whatever level it’s at right now)
4. Follow the teacher’s directions to remove the marbles.

10. Volume Lab
1. Using your ruler, measure the length, width, and height of the small cube in centimeters.
2. Multiply those three numbers (you may use your phone as a calculator) to find the volume.

11. Volume Lab
1. Write down the letters of the four other rectangular prisms in your bag.
2. Make a prediction as to what each one’s volume is.
3. Measure them and calculate the actual volume (length X width X height)

12. Volume Lab B = 8 cm³ C = 27 cm³ D = 64 cm³ E = 16 cm³ F = 24 cm³
G = 32 cm³
H = 32 cm³
I = 32 cm³
J = 64 cm³
K = 128 cm³

13. Volume Lab
1. Predict the volume of a science textbook (in cubic centimeters)
2. Use your ruler to calculate the actual volume.
3. How close were you?

14. Volume Lab
Fill your graduated cylinder back up to 10mL
