2. Science
●
●
●
Science is empirical- meaning it is based on
observation and experiment
Scientists observe and perform experiments on
the physical world to learn about it.
Broken into many sub levels:
–
Biology
–
Chemistry
–
Physics
–
Astronomy
3. Observations
There are two kinds of Observation
●
Qualitative
●
Quantitative
–
–
●
Qualitative: describing how a process happens
Quantitative: measuring or quantifying
something about the process.
These observations lead scientists to formulate
a hypothesis (a tentative interpretation or
explanation of the observations)
4. Experiments
●
●
●
●
When a hypothesis is formulated it must be
tested by an experiment.
An experiment are highly controlled procedures
designed to generate such observations.
The results of the experiment may support
one's hypothesis or disprove it.
When a hypothesis is disproven it must be
modified or changed and once again tested.
5. Scientific Law
●
●
●
In some cases, a series of similar experiments
can lead to the development of a scientific law.
Scientific Laws are brief statements which
summarizes past observations and predicts
future ones.
The Law of Conservation of Mass- “In a
chemical reaction, mater is neither created nor
destroyed.”
6. Theory
●
●
●
One or more well- established hypotheses may
form the basis of a Scientific theory.
A theory is a model for the way nature is and
tries to explain not merely what nature does but
also why.
Atomic Theory- Proposed by John Dalton,
proposes that matter is made up of small,
indestructible particles he called atoms
