32 TEACHING SCIENCE IN THE ELEMENTARY SCHOOL

 Many aspects of health can be considered in connec-
 tion with a trip to the fruit groves, especially the im-
 portance and the ways of preserving fruit.
 The winter conditions can be observed and succession
 of changes that take place in the groves can be asso-
 ciated with seasonal changes. The fertilizing, spray-
 ing, and cultivating all represent examples of applied
 science. For further information see the Department
 of Agriculture bulletin, "The Citrus Industry in Flor-
 ida."

 (13) 6-V. Timbering
 There are many science experiences possible in the
 study of lumbering.
 This unit might include the study of the variety of
 trees in a local area-how they grow, the uses of dif-
 ferent kinds, such as trees used for pulpwood, posts,
 veneer crates, and lumber. The ways trees are cut
 and sent to sawmills, how machines have changed the
 methods of finishing and dressing are other possi-
 bilities. The new uses found for by-products are full
 of opportunities for illustrating science principles.

 (14) 6-V. Florida Parks and Forests
 Florida's national, state, and county parks and forests
 which have been set aside to preserve the native life,
 the beauty and the history of Florida, are accessible
 to practically every school.
 Some well known parks that would be of interest to
 a group of children to visit are: Everglades National
 Park, Highland Hammock State Park, Hillsborough
 River State Park, Gold Head Branch State Park,
 Myakka River State Park, Florida Caverns State Park,
 Torreya State Park, and Fort Clinch State Park. These
 parks not only offer different type of recreation but
 make it possible to observe the different types and
 forms of plant growth, both land and water, native
 wildlife in the natural habitat, beautiful lakes, sand
 hills, forests, nature trails, natural wildlife sanctuaries,
 old buildings and tropical jungles. For further sugges-
 tions see the Department of Education, Florida School
 Bulletin, March 1947, "Using Out-of-Door Florida as
 Instructional Material," and consult the publications of
 the Florida Forestry and Park Service listed on page
