Describes a project for junior high and senior high school students designed to safely preserve hard-bodied marine invertebrates. Details the materials and procedures used in this technique. Stresses the use of non-toxic solutions and producing a lifelike specimen. (CW)

The virgin forests supply a wealth of knowledge and information concerning soil conditions, climate, etc. which can be readily ascertained from simple experiments. (DF)

By investigation it can be shown that life partnerships are founded on the collaboration between each species of animals and plant-life, and that only those species which integrate themselves into the whole can find their natural places in a forest. (DF)

Provided is a biographical sketch of Percy L. Julian (1898- ), an American Black organic chemist who first synthesized cortisone, testosterone, progesterone, and physostigmine. (CS)

Describes behaviors of the domestic cat in terms of developing students abilities to observe. Discussed are play, territoriality and pecking order, catnip, feral studies, and chasing. (CW)

Describes the use of constructivism in teaching human anatomy. Provides directions for constructing arm-hand and leg-foot models that include extensor and flexor muscles and that are easily and cheaply constructed. Lists resources that provide ideas for using such models depending upon the curriculum implemented in a school or the course that is…

Discusses science activities designed to examine a balanced community in an unspoiled wooded section, including the study of physical and floral characteristics, shrubs, small and large trees, and animals. Indicates that the students' awareness of man's place in nature and nature's place in man is enhanced through such activities. (CC)

Describes the construction and observation of beehives. (SL)
