senses can be fooled so knowing the truth through this is impossible, truth comes from within, personal existence is the only truth
|
|
|
all is change
|
change occurs, ex- time, moon phases, seasons, age, death; individuals can be fooled but together truth can be known
|
|
|
qualitative
|
description with no measurements
|
|
|
quantitative

|
|
|
natural events
|
natural events are traced to a natural cause, not supernatural
|
|
|
atom
|
smallest particle of an element that retains the properties of element
|
|
|
molecule
|
a particle of one or more atoms held together by chemical bonds
|
|
|
hypothesis
|
based on previous observations and offered as an answer to the question being asked
|
|
|
experiment
|
carefully controlled observations that either support or refute the hypothesis, leading to a conclusion
|
|
|
control
|
all the variables not being tested remain constant, and are then compared w/ the experimental situation where only the variable being tested is changed
|
|
|
literature search
|
tells a scientist if others have noticed the same patterns and have offered similar explanations
|
|
|
inductive reasoning
|
creating a generalization as a result of many observations that support it, and none that contradict it
|
|
|
deductive reasoning
|
process of generating hypotheses about how a specific experiment or observation will turn out, based on a well supported generalization
|
|

electron
|
negatively charged particles with little mass
|
|
|
proton
|
positively charged subatomic particle found in the nucleus, large mass= to neutron
|
|
|
neutron
|
uncharged subatomic particles found in the nucleus with mass same as protons
|
|
|
element
|
substance that can not be broken down or converted to other substances by ordinary chemical means
|
|
|
atomic number
|
number of protons in the nucleus of a particular element
|
|
|
compound
|
substance whose molecules are formed by different types of atoms
|
|
|
ionic bond
|
an electron is transferred, creating positive and negative ions that attract one another
|
|

inorganic compound
|
molecule that doesnt contain both carbon and hydrogen
|
|
|
organic compound
|
molecule that contains carbon and hydrogen
|
|
|
water
|
dissolves many polar and ionic compounds necessary for cell function, organizes nonpolar compounds to form cell membranes, many biochem rxns occur in H20

|
|
dissachharide
|
2 monosaccharides are linked

polymer of many monosaccharides
|
|
|
glucose
|
most common monosaccharide in living organisms, has 6 carbons
|
|
|
lipids
|
contain large regions composed almost entirely of hydrogen and carbon, these regions make lipids hydrophobic and insoluble in water, energy storage molecules- oils, fats, waxes, phospholipids, steorids
