Chemistry - Answer: Science that seeks to understand the
behavior of matter by studying the behavior of atoms and
molecules; studies change of matter
,Microscopic level - Answer: atomic and molecular view
Macroscopic level - Answer: lab view
Structure and Properties: Same atom/molecule - Answer:
Properties are different because structure form differently or are
not the same
Structures and Properties: Temperature - Answer: different
structures at different temperatures "HOT" demonstration
Clinical: Heart disease - Answer: fat deposit (plaque) is fixed with
metal stent; starts at low temp.=normal wire; hearts have higher
temp. so stent forms
Scientific knowledge is empirical... - Answer: based on
observations and experiments
Scientific method purpose - Answer: process for understanding
nature by observing in nature and its behavior, and by conducting
experiments to test ideas
, SM 1) Observation - Answer: "data"
SM 2) hypothesis - Answer: tentative interpretation of
explanation of the observations
good hypothesis=falsifiable
SM 3) scientific law - Answer: brief statement that summarizes
past observations and predicts futures ones; allows testing
SM 4) theory - Answer: model for the way nature is and tries to
explain why nature does what it does; validated by experiments
SM 5) Further experiments - Answer: Continue studies
Two unit systems - Answer: SI system & English system
SI base units - Answer: m - Meter - Length.
s - Second - Time.
mol - Mole - Amount of Substance.
A - Ampere - Electric Current.
K - Kelvin - Temperature.
