Meaning of Science and Biology
Science can be defined as a systematic process of making inquiry about the living and non-living things in our environment. Science is both an organized body of knowledge and a process of finding out knowledge. Biology is the branch of science that studies living things. The word ‘biology’ is derived from two Greek words: ‘bios’ which means life, and ‘logos’ which means study. Biology therefore means the study of life or of living things. Biology has several branches, these include- Botany (study of plants)
- Zoology (study of animals)
- Morphology (study of the external features of living things)
- Anatomy (study of internal structure of living things)
- Physiology (Study of how living things function)
- Ecology (study of the relationships between living things and their environment),
- Genetics (Study of how living things inherit characters from their parents) etc.
- Define the terms (a) Science (b) Biology
- State five branches of biology.
- Of what use is (a) science (b) biology to man?
Methods of Science (The Scientific Method)
The method of science involves systematically making inquiries about something under study. It begins with observation (that is, looking at something carefully with a view to finding an answer to a question). This involves using all the senses i.e. sight, hearing, touch, feeling, pressure, taste, etc. and instruments (e.g. ruler, microscope, magnifying lens, weighing balance, telescopes, barometer, etc.) where necessary. Observation is followed by a hypothesis i.e. a sensible, reasonable guess which is capable of being tested or verified.You are viewing an excerpt of this lesson.
