USING FLORIDA ENVIRONMENT IN TEACHING 37

 Thus, the remaining colors of light seem to be yellow
 to red. Colors of light are visible when they fall on
 some object. When the sun is below the horizon so
 that it cannot be seen, the clouds will show the bril-
 liant colors.
 In the low flat peninsula of Florida where there is a
 great amount of moisture and cloud formations in the
 atmosphere, sunsets will be brilliant.
 This phenomenon is applicable to the concepts developed
 in elementary science classes in all parts of the state.
 The beautiful sunsets seen by the first grader will add
 meaning to the concept, the sun gives us light; while
 the second grade pupils will realize that the sunlight
 passes through the air that surrounds the earth. The
 third and fourth grade pupils are using the concepts:
 the earth spins like a top, and light rays may be bent
 in passing from one substance through another. The
 pupils of the fifth grade will be making application of
 the concept that the sun's rays strike the earth and the
 sixth grade pupils will understand that the brilliant sun-
 set does not happen each day because of the rapidly
 changing conditions of weather.
(25) 6-V. Minerals of Florida.
 Florida is an important non-metallic mineral producing
 state. It stands first in the production of phosphate;
 second in Fuller's earth, a clay used in clarifying min-
 eral and vegetable oils; is a center in production of
 kaolin used in white ware; is an important producer
 of limestone, lime and cement; has sand deposits suit-
 able for the manufacture of brick and tile as well as
 pottery. Mines and plants connected with these min-
 ing industries provide many learning possibilities for
 Florida boys and girls.
(26) 3-V. Florida's Pulp and Paper Industry
 There are several paper mills already located in Flor-
 ida. The pulp mills are able to use pines, straight or
 crooked, fast-growing or slow-growing, thrifty or
 stunted, limby or clean-boled, thus utilizing otherwise
 wasted wood. There are paper mills at Panama City,
 Port St. Joe, Jacksonville and Fernandina. Much can
 be learned in a study of the process of paper-making.

 The Gulf Stream is not only an interesting phenomenon
 of the ocean near the East Coast, but is an asset to
