scientific methos
three main steps of the scientific method
observing
hypothesizing
experimenting
the closeness of a measurement to the actual, exact number
Accuracy
in the formula p=m/V m =
mass
Ar
gold
Mn
manganese
gathering data about material
observing
the consistency or reproducibility of a measurement
Precision
solid,liquid,gas
3 common states of matter
Si
silicon
symbol for platinum
pt
suggesting explanations for observations
hypothesizing
the coldest possible temperature at which molecules cease vibrating
absolute zero
in the formula p=m/V V=?
volume
U
uranium
Pu
plutonium
setting up carefully controlled artificial situations (experiments to test a hypothesis
experimenting
p=m/V
