From Wednesday
Metric System: Length
Base unit is the meter “m”
1 centimeter is as big as the tip of your pinky
1 millimeter is as big as a dime on its edge
1 meter (m)= 100 centimeters (cm)
1 meter (m)= 1000 millimeters (mm)
1 centimeter (cm)= 10 millimeters (mm)
1 kilometer (km) 100 meters (m)

English vs. Metric Units
Which is larger?
A. 1 liter or 1 gallon
B. 1 liter or 1 quart
C. 1 milligram or 1 fluid ounce
1 gallon = 3.79 liters
It would take approximately 3 ¾ 1-liter bottles to equal a gallon.
1 fl oz = 29.573 ml
1 12-oz can of soda would equal
approximately 355 ml.
1 quart = 0.946 liters

Metric Units
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?
A. 1 liter or 1500 milliliters
B. 200 milliliters or 1.2 liters
C. 12 cm3 or 1.2 milliliters*

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.
