Use and preparation of the biological specimen

Abstract

Scope of Study: This is a study of the biological specimen as an aid for teaching secondary biology. The establishment and care of the four common habitat terraria is covered concisely. Some of the potentialities of both the non-flowering plants and the common laboratory grown flowering plants are investigated and practical suggestions offered. The preservation, care, and use of the botanical and zoological specimen is given an effectual review. The practicability of the living animal in the classroom is also given adequate consideration.

Findings and Conclusions: The use of the biological specimen enables the teacher to approach his subject while utilizing more of the discriminatory powers of the student. These aids are not to supplant ordinary classroom methods, instead they are to supplement these methods. The effort required to maintain the useable specimen is an essential part of the teachers' responsibilities. The use of the preserved specimen is an important part of the biological program and one which cannot be eliminated. The representative collection of preserved materials is a vital part of any inspiring program. However, the use of the living plant or animal is advisable when it is practical. The living organism is an asset to the study of the "Life Sciences."
