7. What this means:
One kilometer (km) is a little bigger than half a mile. A meter (m) is a little longer than a yard. A centimeter (cm) is about 1/3 (0.3) of an inch.

8. Why do you have to learn this?
ALL scientists use the metric system.
Anyone understands this type of data no matter what language you speak.
It’s WAY EASIER than the Standard System, which we use in the United States because everything is based on 10

9. LENGTH The base for length is METERS (m).
The tool that is used is a ruler.
You could also use a measuring tape.

10. How to Measure
We will NEVER use inches in science – only meters, centimeters, or millimeters.
Line up the object with the 0, not the edge.
The longer lines are centimeters (cm), the shorter lines are millimeters (mm).

11. How to Measure

51. How do we find the volume of things that aren’t cubes?
Displacement: The amount of water an object moves
This type of volume is measured in LITERS.
Most often we will use milliliters, or mL

52. Volume Volume is measured in LITERS (L).
The tool used to measure volume is a graduated cylinder.
Most often we will use milliliters or mL.
1 mL = 1 cm3 = 1 cc (cubic centimeter)

53. Reading a Graduated Cylinder
Meniscus: the way water curves when in a tube

54. Reading a Graduated Cylinder
Understand what units the graduated cylinder is in
Look at the bottom of the meniscus

55. Practice: How many mL are in the graduated cylinder?
What is the scale?
(Meaning, how much is line worth?)
Each line is worth 1 mL.
14 mL
90 mL
18 mL
42 mL
250 mL

Find the “after” measurement.
Subtract to find the volume of the object.

67. TEMPERATURE
Temperature is a measurement of the amount of heat in something
Temperature is measured in degrees CELSIUS (⁰C)
The tool that is used to measure temperature is a thermometer.

68. Water Boils
Room Temperature
Water Freezes

69. What is the temperature?
94⁰ C

70. MASS Mass is the amount of matter (stuff) in an object
Mass is measured in the base GRAMS (g)
The tool that is used to measure mass is a triple beam balance.

71. How to Use a Triple Beam Balance

72. How to Use a Triple Beam Balance
Double check that the balance mark is lined up.
Place an object on the pan.
Move the masses. START WITH THE SMALLEST MASS FIRST. If it is too small, go to the next biggest mass.
Move the masses until the balance mark is again lined up.

73. Practice: What is the mass?

79. Electronic Scales
Always make sure the scale reads 0 before you put anything on.
If it doesn’t read 0, push the “tare” button.
Never push on an electronic scale – you will break it.

80. Real Practice
Measure each item around the room on the triple beam balance. Record your answer.
Check your answer by measuring the item on the electronic scale at the front of the class.
Return each item to the station you got it from.
