experimental set
the trill set in an experiment that contains the experimental variable
Observational science
science in which hypotheses are supported or denied in the basis of observations alone rather than controlled experiments
Contributions of Aristotle on marine biology
He developed a classification which he called "ladder of life" had descriptions of over 500 species. Also figured out that gills helped fish breath and detailed the anatomy of the cuttlefish
an explanation for observed events that can be tested by experiments
organisms that float or drift in the seas current
inductive reasoning

Approximately how much of the earth is covered by oceans?
philny the elder and contributions to marine bio
37 volume of "natural history" contains info about terrestrial animals and fish and bivalves (shellfish)
represents a body of observations and experimental support have stood the test of time
ocean productivity
the production of organic matter by photosynthetic and chemo synthetic marine organisms
deductive reasoning
a process of reasoning in which observations suggest a general principle from which a specific statement can be derived.
experimental variable
the trial set in an experiment that contains the experiemtnal variable
the study of the oceans and their phenomena such as waves currents and tides.
steps of scientific method
1) making observations
2) using inductive reasoning to form a hypothesis
3) using deductive reasoning to design experiments
4) gathering results
5) drawing conclusions
