 SECTION 2. THE INTER-RELATION OF SCIENCE WITH
 OTHER SUBJECT FIELDS
 Science is not an isolated subject that can be confined to such
classes as biology, chemistry, or physics. Science today is in-
timately connected with every phase of living. This points to the
necessity of the science teacher's working in close cooperation
with teachers in the other subject fields. An understanding of
the work carried on in all subjects will bring appreciations that
will work to the good of all concerned in achieving the common
objective, the education of the child.
 The bulletin Programs of Study in Florida Secondary Schools
 (October, 1946) shows where correlations may be made with
other courses.
 In agriculture we see the application of science principles.
In agriculture classes these principles are developed. The com-
position of the earth's soils, the elimination of soil waste, soil
erosion by wind or water, the study of the seasons, and the
study of climate and weather are all adapted from phases of
earth science. The application of chemistry can be found in such
sections as the development of fertilizers, and healthful food.
Electricity on the farm, the study of farm machinery, irrigation,
and drainage are phases of physics. Agriculture is rich in appli-
cations of biology. These include study of farm animals, growth
of crops, control of insects, and conservation of birds, fish, and
wild animals.
 In home living and home economics courses we find another
field of applied sciences. Applications of heat, use of energy,
time saving devices, maintenance of home machinery, color
effects, rules of architecture and design, choice and preparation
of foods, all are related to science.
 Mathematics and other sciences are intimately related. Many
problems arise directly from scientific situations. Science uses
basic mathematics in interpreting the findings of experiments.
