BASIC SCIENCE AND TECHNOLOGY
THEME: THE HUMAN BODY
PREVIOUS LESSON –
TOPIC: The Human Circulatory System
1. The Structure and Functions of the Heart
2. The Functions of the Blood Vessels
By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and be able to:
1. name some parts of the human heart and major blood vessels;
2. differentiate among arteries, veins and capillaries;
3. state some basic functions of the human heart and blood vessels;
4. describe in simple terms how food and materials are distributed to different parts of the body by, the blood.
The pupils are required to already have learned parts of the body.
The teacher will teach the lesson with the aid of:
Model of the human heart
Mode of blood vessel
Chart/diagram showing blood circulation
METHOD OF TEACHING – Choose a suitable and appropriate methods for the lessons.
Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON
LESSON ONE – INTRODUCTION
The human circulatory system is made of an independent systems that work together. These systems are the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cell s.
THE BLOOD CIRCULATORY SYSTEM
The blood circulatory system delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body.
THE HUMAN HEART
STRUCTURE OF THE HEART
The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.
The human heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles). The right atrium and right ventricle together make up the “right heart,” and the left atrium and left ventricle make up the “left heart.” A wall of muscle called the septum separates the two sides of the heart.
FUNCTIONS OF THE HEART
1. It is a muscular and pumping organ.
2. It pumps blood to other parts of the body.
3. The pumping action keep human being alive.
LESSON TWO – BLOOD VESSELS
The blood vessels are part of the circulatory system and function to transport blood throughout the body. There are three major types of blood vessels:
1. The arteries are the blood vessels that carry oxygen – rich blood from the heart to the tissues of the body.
2. The capillaries smallest blood vessel that enable the actual exchange of water and chemicals between the blood and the tissues.
3. The veins are blood vessel that carry blood from the capillaries back toward the heart.
LESSON THREE – REVISION OF THE LESSON
To deliver the lesson, the teacher adopts the following steps:
1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
2. Sources and brings the models of human heart and blood vessels to the class;
Pupil’s Activities – Draw and label the human heart and the blood vessels.
3. Guides pupils to name parts of the heart and the blood vessels using diagrams in the textbook or charts;
Pupil’s Activities – Trace the movement of food and other materials by the blood to all parts of the human body using a chart.
4. Guides and moderate class discussion on blood circulation;
State the basic functions of human heart and blood vessels.
Pupil’s Activities – Active participation in the class discussion.
- To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson – revision of first term’s lesson.
1. identify the parts of the human heart and the blood vessels.
2. state two distinguishing features of the arteries, veins and capillaries.
3. state two functions each of the heart and the blood vessel.
4. describe the blood circulation process.
