• Remember any measurements you make during your Science Project in the English system must be converted to metric units
Overview
• Metric Ruler and Meter Stick Rules• Metric Pretest (Example pg )• Metric Definitions • Common Metric Units (Length) • Metric Measuring Exercise• Metric System Pretest (Answers)
Metric Ruler & Meter Stick Rules
• They are only to be used for measuring• They are not toys• They are not propellers• They are not light swords• They are not tapping devices• When not in use – they will be placed
back on or in your desk

Convert 100 inches into
• Total number of Feet and Inches
• 12” + 12” + 12” + 12” + 12” + 12” + 12” + 12” =• 96” or 8’
• 100” – 96” = 4” Answer is 8’ + 4”
• Now, convert it into total Yards, Feet, and Inches
• 2 yards + 2 Feet + 4 inches
Instructions for taking Cornell Notes
• Starting on pg 3, use a ruler to put a Cornell Line on the next 2 Note pages (odd pages) in your INB– Put the line 1/3 of the way in from the book fold
• Write Blue colored words to the left of the line
• Write Black colored words to the right of the line
• You do not need to write Red or Orange colored words
• Underline words that are underlined for emphasis
Metric Notes – An introduction to Scientific Measurement
• What are the 5 Areas of Scientific Measurement and what do they measure?
OrOr
Let’s get started with your notes
• Metric System – standard system of measurements used by __?__
• Scientists
• Decimal system - based on multiples of __?__• ten
• SI - basic unit/s of metric (system) measurement– Abbreviation for International System of Units
Metric Prefix Abbreviations and Symbols-
• kilo - (k) King
• hecto - (h) Human
• deca - (da/D/Dk) Dragon
• Basic Unit - (meter - m / liter – L / gram - g) Bear
• deci - (d) Dog
• centi - (c) Cat
• milli - (m) Mouse
Temperature -
• Degree of warmth (amt. of heat) of a body or environment.
• Measure of the average kinetic energy of the particles in a sample of matter
• Expressed in terms of units or degrees designated on a standard scale.
Temperature - • SI Unit (Basic unit of metric measurement )–• Degrees Celsius ( 0C )
• Equipment – • Celsius thermometer
• Freezing Point (FP) of water – • 0 0C
• Boiling Point (BP) of water - • 100 0C
Length -
• Distance between two points
• SI Unit (Basic unit of metric measurement ) - Meter • km > hm > Dm > m > dm > cm > mm• Meter slightly shorter / longer than a yard
(Hint: a Meter stick is 39 inches long)
• Equipment – • meter stick / metric ruler
Look at the Metric Ruler on your desk
• What are the smallest units on a metric ruler• millimeters (mm)
• What Part of your hand is about the size of a millimeter?–
• thickness of your fingernail
• How many mm are there on a meter stick?• 1,000
Look at the Metric Ruler on your desk
• What are the next biggest units on a metric ruler?
• centimeters (cm) • How many cm are there on a meter stick?• 100
• What part of your hand is about the size of a cm?
• Width of your finger
• How many dm are there on a meter stick?• 10
Look at the Meter Stick on your desk
• What part of your hand is about the size of a dm?
• Width of your hand
• How many cm on a metric ruler?• 30• How many mm on a metric ruler?• 300• How many dm on a metric ruler?• 3
Volume -
• Amount of space an object takes up in a liquid or gaseous state
• SI Unit - Liter• kl > hl > Dl > L > dl > cl > mL• Liter is slightly smaller / larger than a quart
• Equipment – graduated cylinder, beaker
Measuring Volume
• http://www.wisc-online.com/objects/ViewObject.aspx?ID=gch302
Mass -
• Amount of matter in an object • Weight is a function of gravity (Mass isn’t)• Would your weight change if you were on the moon?• Would your mass change if you were on the moon?
• SI unit - Gram • kg > hg > Dg > g > dg > cg > mg• gram has approx. mass to 1 paper clip
• Equipment - • Triple Beam Balance or digital scale
Weight -
• Amount of heaviness of something• Changes with gravity
• SI Unit – Newton• Equipment - same as Mass
Density -• measurement of how tightly matter is crammed together (mass per
unit volume)
• SI Unit - cgs unit of grams per cubic centimeter (g/cm 3 ). • One of most common uses of density is in how different materials interact when mixed
together• Wood floats in water because it has a lower density than H2O• Anchor sinks because the metal has a higher density than H2O• Helium balloons float because the density of the helium is lower than the density of the
air
• Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
• Small Scale Equipment:
• Equipment - same as Mass
Density -• Small Scale Equipment:
•
• Regular shaped object (Scale - mass and Ruler - Volume)
• Mass divided by volume
Density -• Small Scale Equipment:
• Irregular shaped object: (scale – mass and water filled graduated cylinder)
• -- immerse object in water and measuring the volume of water it displaces)
Metric Reflection (on an Example Page)
• Draw a small hand and put arrows pointing to the 3 areas of the hand that relate to mm, cm and dm
• Come up with a Metric Reflection using:– King– Human– Dragon– Base Unit– Dog– Cat – Mouse
Make sure both pictures have plenty of color and imagination
