Lesson Note For JSS2 Basic Science (First Term)

Week 1 – Living Things (Habitat)

Overview – Every living organism, whether plant or animal has a particular place where it normally lives. The kind of place or environment where an organism normally lives is called its habitat. Habitat is any environment in which an organism naturally lives. There are three types of habitats, aquatic (water), terrestrial (land) and arboreal (tree trunks and tree tops) habitats. This week, we shall learn about the dwelling place of living things – the habitat. To learn more, Click here

Week 2 – Adaptation of Living Things to their Habitat

Overview – For a living thing to live comfortably in its habitat, there are certain things it must have adapted to it. Organisms such as fishes that live in aquatic habitats have developed certain characteristics that make the able to survive in water. One of the characteristics of fishes is the use of gills for respiration under water. Organisms found in terrestrial and arboreal habitats also have certain adaptations to their habitats. This week, we shall learn about the adaptation of living things to their environment.

Week 3 – Air Pollution

Overview – Air pollution is the process of making air unsuitable for breathing by both plants and animals. The release of toxic gases (sulphur (IV) oxide, carbon (II) oxide) and particles (dust) into the air causes air pollution. Air pollution can cause damage to an organism’s respiratory organs. The particles released into the air can reduce visibility. One way of reducing air pollution is by educating people on the dangers of air pollution. This week, we shall learn about air pollution – its sources, consequences, and control.

Week 4 – Uniqueness of Human Beings

Overview – In science, human beings are always considered as higher animals. This is because, they can move from place to place, possess no chlorophyll and cannot make their own food amongst other characteristics. Human beings are said to be unique from other animals because of the possession of certain special characteristics. Human beings are highly intelligent animals with a highly developed brain that enables him to reason, plan and solve problems better than other animals. This week, we shall learn about the uniqueness of human beings. We shall also learn types of uses of intelligence.

Week 5 – Measurement of Growth and Developmental Changes 

Overview – You would have noticed that a baby does not remain the same size after birth. A baby is said to be growing as he or she increases in size gradually as the baby is being fed with breast milk. As growth is taking place, other changes occur, leading to the overall physical development of the baby. Development is a series of orderly changes by which a living thing comes into maturity. This week, we shall learn about how to measure growth and developmental changes. To learn more, Click here…

Week 6 – Human Development 

Overview – Human development is a lifelong process of physical, behavioural, cognitive, and emotional growth and change. Throughout the entire human development, enormous changes occur. The stages of human development include infancy, childhood, adolescence and adulthood. At each stage of changes occur, from learning how to walk as an infant to becoming more physically and intellectually intelligent as an adult. This week, we shall learn about human development and the stages of human development.

Week 7 – Human Development (II)

Overview – Each of the developmental stages i.e. childhood, adolescence and adulthood is associated with some characteristic features. This week, we shall learn about characteristic features of developmental stages. We shall also learn about the temporary and permanent changes in growth and development.

Week 8 – Changes in Matter 

Overview – Matter is anything that has mass and occupies space. It undergoes certain changes which may be as a result of growth in plants and animals.  There are two types of changes in matter – temporary and permanent changes. Temporary change is a change in which no new substance is formed and it can be easily reversed. Permanent change is a change that is not easily reversed because a new substance is formed. This week, we shall learn about changes in the matter – the types of change, examples and their characteristics.

Week 9 – Changes in Living Things

Overview – Growth can be defined as the quantitative increase in size, weight and height of a living thing. These changes which are observable and measurable accompany age increase.  Growth changes occur in height, weight and size. Developmental changes begin from conception of the child to adulthood.  This week, we shall learn about the changes in living things.

Week 10 – Changes in Non-Living Things

Overview – In nature, there are two types of changes – physical and chemical change. Physical Change is a temporary change that can be easily be reversed. A chemical change is a permanent change that cannot be easily reversed. These changes are different from one another, while a new substance is formed after a chemical change occurs, a physical change does not produce any new substance. This week, we shall learn about the changes in non-living things.
