First course in biology

A clear, approachable introduction to biology, this text is aimed at secondary‑school learners who need a single, unified course rather than isolated botany, zoology or physiology lessons. It bridges the gap between informal nature‑study and the more formal science of later grades, offering a gentle yet thorough grounding in the living world.

Divided into three parts—plant biology, animal biology, and human biology—the book lets teachers start wherever fits their schedule. Practical suggestions guide a year‑long, half‑year, or flexible term plan, with recommendations for how often to study each section as seasons change. Real specimens and hands‑on observation are emphasized, keeping the focus on what students can see and touch instead of abstract theory.

The overall philosophy favors learning through everyday life, highlighting how plants adapt, how animals survive, and how human bodies function. By keeping explanations simple and avoiding unnecessary jargon, the text invites beginners to develop a solid, lasting understanding of living processes.
