Significant numbers are... - ANSWER-all non zero numbers, zeros between numbers,
and zeros to the right of the number.
ex 0.01230 sig numbers are: 1230
___ variable goes on the x axis
___ variable goes on the y axis - ANSWER-independent variable goes on the x axis
dependent variable goes on the y axis
Independent variable - ANSWER-the variable being manipulated by the experiment
Dependent variable - ANSWER-the variable that may change because of the
independent variable
Mean - ANSWER-average
add up all numbers and divide
Median - ANSWER-the "middle" value in the list of numbers in numerical order
Mode - ANSWER-Number that appears most often
Range - ANSWER-Difference between highest and lowest number
Igneous Rock - ANSWER-formed when hot magma cools beneath the ground
or
, lava cools above the ground
forms crystal like/ glassy rocks
ex: granite and pumus
Sedimentary Rock - ANSWER-Changed by pressure
does not involve heat
Usually near water/ involves water
sometimes contain fossils
forms from previously weathered and erroted material which may have been igneous,
sedimentary, rock metamorphic rock.
ex: dolemite, limestone
Metamorphic Rock - ANSWER-Has been changed by great heat and pressure
altered, partially remelted
