Science is based upon observation. However, observation
1
is not science. Scientists generally state a problem. Then

guides them in their observations. But without observation people generally are not

of a problem. This then raises a question

comes first, the observation or the problem. Curiosity awakens a

, he formulates a specific statement that can be tested. This statement is called a hypothesis. It is the starting point for an experiment.
9
experimenting, the scientist tries to show or prove that the hypothesis is true

false. He must use good

to create an experiment that

the problem. The experiment must produce
13
information or data. The data gathered during the experiment are observations.
Observations can be made directly and indirectly. For indirect observation, instruments are often used.
14
instruments used by modem scientists are quite simple, others are very

To complete his experiment, the scientist must state his observations

17
he can make more exact comparisons or descriptions to

his hypothesis. The results of a scientific experiment
