THE TEACHING OF CHEMISTRY 37

understanding of the objectives of science instruction in the
secondary school, nor on a recognition of the psychology of
youth at the high school level.
 Center interest on chemistry for Florida. At present many in-
dustries exist in Florida because of chemical research. The alert
teacher will investigate local and state industries to have these
serve as a hub for the study of applied chemistry. Outstanding
fields in which chemical research is playing a major part are
citrus products, paper manufacture, starch derivatives. Indus-
tries in which chemical processes are basic produce sugar, lime
and cement, charcoal and wood derivatives, sulphuric acid, and
dry ice.
 For its future development, Florida is unique in having many
potential industries which are chemically feasible such as those
based on the use of soy bean, peanut, lemon grass, and native
plants such as palmetto, coconut, mangrove and kelp. New in-
dustries based on Florida resources, which are now being shipped
for processing outside the state, may be developed from phos-
phate, zirconium, magnesium, titanium, turpentine, tung oil,
ceramics, diatomaceous and fuller's earths.
 Problems in communities of Florida which can be solved
through the application of chemistry are water purification,
sewage disposal, weed eradication and suppression of pollen, in-
sect control, soil deficiency, reclaiming waste products.
 Objectives of the teaching of chemistry. The following ob-
jectives seem valid:
 1. To show the powers for good and evil of man's control of
 nature through chemistry.
 2. To enhance the appreciation of chemistry's contribution
 to the welfare of mankind.
 3. To train the students to become intelligent consumers of
 our nation's goods and services.
 4. To teach the chemistry of the human body in such a man-
 ner as to contribute to health and safety.
 5. To give a basic understanding of agricultural and indus-
 trial processes.
