The Metric System is a system of measurement that is used by scientists all over the world. Most countries only use the metric system. There are different metric units depending on what

we want to measure: Length: Meter (m) Volume: Liter (l) Mass: Gram (g) These are called basic units. When you add a prefix to a basic unit you change its value. Kilo (k) = 1000 Hecta (h) = 100 Deca (da) = 10 BASE UNIT = 1

Deci (d) = .1 Centi (c) = .01 Milli (m) = .001 Kilo (k) 100 0 Hecta (h) 100 Deca (da)

10 1 Deci (d) .1 Centi (c) .01 Milli (m)

.00 1 Kilo (k) 100 0 Hecta (h) 100 4.___.___.___. = 4000 m ________

Deca (da) 10 1 How do you use the Ladder Method? 1.Determine your starting point. 2.Count the jumps to your ending point 3.Move the decimal the same

number of jumps in the same direction Deci (d) .1 Centi (c) .01 Milli (m) .00

1 4 km= ________ m Ending Starting Point Point How many jumps does it take? The basic unit of length in the metric system is the meter and is abbreviated using a lowercase m. Metric Units

1 Kilometer (km) = 1000 meters 1 Meter = 100 Centimeters (cm) 1 Meter = 1000 Millimeters (mm) To measure length, we use a ruler.

How many millimeters are in 1 centimeter? 1 centimeter = 10 millimeters 28 What is the length of the line in millimeters? _______mm What is the length of the line to the nearest centimeter? ________cm ***HINT: Round to the nearest centimeter 3 NO decimals. 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. Metric Units 1 liter (L) = 1000 milliliters (mL) 1 milliliter (mL) = 1 cm3 = 1 gram*

To measure volume, use a graduated cylinder. 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 67 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. _______ ml ______ ml ______

52 37 23 ml What is the volume of each cylinder? Mass refers to the amount of matter in an object. The base unit of mass in the metric system in the kilogram and is represented by kg. Metric Units 1

Kilogram (km) = 1000 Grams (g) 1 Gram (g) = 1000 Milligrams (mg) The objects are placed on the scale Then you move the weights on the beams until you get

the lines on the rightside of the scale to match up. To measure mass, we use a triple beam balance. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? ______ 40 + ______ 30 + ______ 1.8 = ________
