Question Answer
Mass: The amount of matter in a substance.
Gram: Basic unit of mass.
What are examples of units of metric mass? Kilograms, hectograms, decagrams, grams, decigrams, centigrams, milligrams.
What are the labels of units of metric mass? kg, hg, dag, g, dg, cg, mg.
What are the common units of mass in the English/standard system? ounces, pounds, tons.
What are the labels for English mass? oz, lbs, T (capital)
How is mass measured? By using a balance.
Volume: The amount of space a substance takes up.
Liter: The basic unit of volume.
What are examples of units of fluid metric volume? kilometers, hectoliters, decaliters, liters, deciliters, centiliters, milliliters.
What are the labels of units of fluid metric volume? kL, hL, daL, L, dL, cL, mL.
What are other units of fluid volume In the English system? fluid oz., cups, pints, quarts, gallons.
What are the labels of the other units of fluid volume? fl.oz., c., pts., qts., gals.
What is liquid or fluid volume measured with? a graduate.
What are examples of solid metric/English volume? any distance unit with the word cubic in front of it. (ie cubic meter, cubic centimeter)
Why do certain labels have to be cubed? the solid volume of a rectangular object is 3 dimensional and measures 3 distances and needs a ruler to measure it.
What are labels for solid metric volume? km(3), hm(3), dam(3), m(3), dm(3), cm(3), mm(3).
What are labels for solid English volume? in(3), ft(3), yds(3), mi(3).
Distance: The amount of separation between two points.
Meter: the basic unit of distance.
What are examples of units of metric distance? kilometers, hectometers, decameters, meter, decimeter, centimeter, millimeter.
What are the labels of distance? km, hm, dam, m, dm, cm, mm.
What are examples of units of English distance? Inches, feet, yards, miles.
What are labels of English distance? in, ft, yds, mi.
What is distance measured with? Ruler or meter stick.
Density: The amount of mass in a certain volume.
What is the formula for density? D=M divided by V.
Why does density have a double unit label? it involves two different types of units (mass and volume)
Examples of labels for density: any mas unit divided by a volume unit (g/cc, g/mL, kg/m(3)
What is step one of determining the increments? Subtract the difference between any two numbers on the graduate and write that number inside the division box.
What is the second step of determining the increments? count the number of lines between the numbers. It will always be 5 or 10. Put that number outside of the division box.
What is step three of determining the increment? Divide. The quotient is the increment you have to know this to read the graduate correctly.
Measurement: comparing something to a known standard.
What is the metric system abbreviation? S.I= System International.
Weight: the measurement of the pull of gravity on a substance.
What are all the prefix's? kilo, hecta, deca, base, deci, centi, mili.
What are the values of each of the prefix's? 1,000, 100, 10, 1, .1, .01, .001.
Liquid displacement volume: used to measure the volume of irregularly shaped objects.
what is the label for liquid displacement? cc, or cm cubed.
How do you read a graduate? read below the meniscus.
How do you find the mass of a liquid? weigh the graduate by itself, put 10 mL of water, find the mass of the graduate and liquid together, subtract the difference.
How do you find the volume of an irregular object? Fill a graduate with water higher then the object, read the level, put the object in the water, read the level again and subtract the difference.
What also measures distance? a trundle wheel.
