  • 3rd side (hint)
Mass
a measure of how much matter is in an object
constant
Weight
The measure of the force of gravity on an object
6 times less on the moon
Density
A measurement of how much mass of a substance is conatained in a given volume
Think Mass/Volume
Inference
A logical interpretation based on observations and prior knowledge
Think I-I
Hypothesis
A possible explanation for a set of observations or an answer to a scientific question: MUST BE TESTABLE
Nope...
Manipulated Variable
the one factor a scientist changes in an experiment
Independent variable
Responding Variable
the factor that changes as a result of the manipulated variable in an experiment
Dependent variable
Controlled experiment
an experiment in which all variables except one are kept constant
Control!!!!!!!!!
Science
a way of learning about the natural world through observations and logical reasoning leading to a body of knowledge
duh........
Scientific theory
a well tested idea that expplains and connects a wide range of observations
......nope
scientific law
a statement that describes what scientists expect to happen every time under a particular set of conditions
LAW not theory
volume
a measure of how much space matter occupies(lxwxh)
not constant
centimeters cubed (cm3)
the unit for measuring volumes of solids (mL=cm3=cc)
nopers
grams per centimeter cubed (g/cm3)
unit used to measure density of a solid
blah
density formula
mass diveded by volume (mass/volume)
milli
.001 = one thousandTH of a meter/gram/liter
K-H-D-M-D-C-M
centi
.01 = one hundredTH of a meter/gram/liter
K-H-D-M-D-C-M
deci
.1 = one tenTH of a meter/gram/liter
K-H-D-M-D-C-M
deka
x10 = 10 meters/grams/liters
K-H-D-M-D-C-M
hecto
x100 = 100 meter/grams/liters
K-H-D-M-D-C-M
kilo
x1000 = 1000 meters/grams/liters
K-H-D-M-D-C-M
meter
in 1875 scientists calculated 1/10000000 of the distance from the equator to the north pole
K-H-D-M-D-C-M
meniscus
the bottom of the curved surface(line) that determines the measurement(for volume) of a liquid(or irregular shaped object) in a graduated cylindar
Think Krawczuk...
Celcius
the temperature scale on which 0 and 100 are the temps. at which water freezes and boils
not Farenheit
Gram
In 1875 scientists decided to use water measured at sea level at 23 degrees C
1 gram = 1 mL of WATER
K-H-D-G-D-C-M
Liter
the standard unit of volume of metrics 1 liter = 1000 cm3
K-H-D-M-D-C-M
