Their very survival depended on acquiring this knowledge and passing it on from generation to generation.

Familiarity with the phenomena should precede their explanation, and attention to the concrete object should precede abstract theory.

Perhaps this is another instance in which following the course of history pays off.

Children know, for example, that fish resemble other fish, frogs resemble other frogs, and that fish and frogs are different.

In the beginning, children can focus on any attribute—size, color, limbs, fins, or wings—but then should gradually be guided to realize that for purposes of understanding relatedness among organisms, some characteristics are more significant than others.Eventually, scientists produced and tested the theories and models that are used to explain people's observations.They came to understand the living environment first through observations, then classifications, then theories.SFCSM: States of Matter: Solid, Liquid and Gas Ask Eric Solutions and Concentrations SFCTM: Theories of Matter SFCPF: Pressure in Fluids Mediacen: Seawater vs Fresh Water TLMTT: The Living Machine as a Teaching Tool Chemistry Teaching Resources WWW Chemistry Resources Organic Chemistry Resources Worldwide Chemistry Resources Links for Chemists / Virtual Library Chemistry Section Chemistry in the Yahoo!Directory High School Chemistry Resources on the Web Science Teachers' Resource Center General Chemistry Online: Home Computational Chemistry Resources on the WWW The Catalyst: Chemistry Resources For Teachers UCSB Libraries - Chemistry Chemistry Resources on the Internet [Internet Resources] Chemistry I Index WWW Chemistry Resources Inorganic Chemistry Resources Chemistry Resources The Chemistry Hypermedia Project at Virginia Tech US FDA/CFSAN Library of Chemistry Information Chemistry and New Zealand Sheffield Chemdex - Home web links homepage OHIO STATE UNIVERSITY-RESOURCES FOR ORGANIC CHEMISTRY Instructional Resources for Chemistry Caltech Library System Organic Chemistry Resources Quiz Hub Chemistry Links Description: Documents about Chemistry produced or collected by the Pentagon and distributed by Storming Media, including ones about Biochemistry; Industrial Chemistry and Chemical Processing; Inorganic Chemistry; Isotopes; Organic Chemistry; Pharmacology; Physical Chemistry; Polymer Chemistry; and Toxicology.: Storming Media provides unclassified reports and documents from the Pentagon, most about science, technology or policy.General similarities and differences among organisms are easily observed.
