Below are the Excerpts (Samples) of the 2023 Complete Biology Lesson Notes for SS1 First Term

WEEK 1: BIOLOGY AND LIVING THINGS

CONTENT

• Biology as Inquiry inScience
• Process or Method of Science
• Microscope Parts and Functions

BIOLOGY AS AN INQUIRY IN SCIENCE

Science is the study of nature (living and non-living things).  Biology is a science that studies living things in nature. Biology was formed from the Greek words “Bio” (meaning life) and “logos” (meaning, study of).

The organisms studied in biology are generally classified into plants and animals. Therefore, biology is a science subject that can be subdivided into two main branches or subjects namely:

• Botany –the study of
• Zoology – the study of animals.

Other branches of biology include zoology, botany, microbiology, parasitology, anatomy, physiology, biotechnology, etc.

RELEVANCE OF BIOLOGY

Biology has found great applications in many areas of human life, some of which include:

1. Medicine: Production of drugs and vaccines for preventing and curing many diseases e.g. penicillin, organ transplant e.g. kidney (renal) transplant, in-vitro fertilization in infertile couples.
2. Agriculture: Production of hybrid (crops and animals with desired qualities), use of biological pestic.ides to control agricultural pests
3. Bioremediation i.e. use of naturally occurring bacteria to clean up oil spills and toxic
4. Biotechnology: Use of genetic engineering to fight genetic diseases.
5. Food production: Production of single cell protein (SCP) to reduce protein deficiency problem, food storage and preservation

EVALUATION

1. What is
2. Describe the following branches of Biology (a) parasitology (b) anatomy (c)

PROCESS OR METHOD OF SCIENCE

This is a systematic approach used to investigate enquiries arising from any observation made in nature. Therefore, the scientific method is the tool used to unravel the mysteries of life. The scientific methods include the following steps:

• Observation
• Classification
• Inference
• Measurement and Identification
• Hypothesis
• Experiment
• Control or Conclusion
• Theory or Law

The starting point of scientific method is observation which involves the use of the senses to describe what one has seen or felt about an object. The observation then leads to classification, then to inference (logical reasoning) and later to measurement and identification of the existing problem. This is followed by hypothesis which is a reasonable explanation for an observation made and which can be tested experimentally. A tested hypothesis may be accepted, rejected or modified to form a new hypothesis. A tested hypothesis that is found to be repeatedly true within the limits of available evidence becomes a theory. A theory is therefore an aggregate of many verified hypotheses. An extensively tested and proven theory becomes a law or principle which is still subject to change due to continual experimentation or research. To carry out a successful experiment (void of false conclusions), a parallel experiment called controlled experiment is usually set up. This is done by keeping constant all factors affecting the result of the main experiment and varying the factor being tested.

Experiments should be reported following a generally accepted pattern laid down by scientists. The pattern includes:

1. Aim: the purpose of the
2. Apparatus/ materials required.
3. Method /procedure followed
4. Observation made.
5. Conclusion based on observation made and final result got.

Note: Precaution or care that should be taken against dangers/hazards can also feature during experimentation.

EVALUATION

1. Define (a) Hypothesis     (b) Theory     (c) Principle
2. List the steps in scientific methods.

MICROSCOPE PARTS AND FUNCTIONS

A microscope is an instrument used in magnifying and viewing organisms smaller than 0.1mm that is too tiny to be seen by the human eyes. A compound light microscope consists of the following parts:

1. Revolving nose piece: it is used for selecting lens to be used and to be in line with the eye
2. Objective lenses (low, medium and high power): for magnification of object
3. Eye piece lens or ocular: for viewing magnified
4. Body tube: provides attachment to eyepiece, revolving nose piece, low-power, medium-power and high-power objective lens.
5. Coarse focus knob: for focusing on object at low power.
6. Fine adjustment knob: for focusing on object at medium and high power magnification so that object is sharper at focus.
7. Arm: for lifting or carrying the microscope.
8. Clip: for holding glass slide on stage.
9. Stage: for displaying slide and specimens under focus.
10. Condenser: regulates the amount of light rays entering the microscope and object.
11. Knob: to raise and lower the
12. Base: for balancing the microscope on the
13. Mirror: for collecting light rays and directing them to condenser and

EVALUATION

1. List five major parts of a microscope and their
