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

Volume of a Regular Shaped Object -

• Length x Width x Height

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
