The world of living creatures that are present everywhere but are too small to be seen
with the naked eye, is said to be a world of micro-organisms. They are omnipresent;
found floating in the air and in water, moving about in the soil and on plants, inside our
bodies and those of all animals. Some of these tiny creatures are disease-causing
(germs). However, most are harmless. To know more about this world, let us explore
the chapter.In this chapter, you will learn about Microorganisms: Categories, and
habitats. Useful microorganisms, harmful microorganisms. Food preservation. Nitrogen

Chapter 4: Materials: Metals and Non-Metals

This chapter deal with the properties of metal and non-metal learn how to identify what
are the basic difference in chemical and physical properties of metal and non-metal
with the appropriate example given in the NCERT text book. Read all the important
reaction related to metal and non-metal and how they react with acid-base and their
fundamental properties. You have already studied about elements as being pure
substances that each are made up of one kind of atoms only.

For the convenience of study, these elements are divided into two broad classes:
Metals and non-metals. This division of elements is based on the fact that there are
certain properties that are found only in metals and certain others that are found only in
non-metals. But, there are also some elements that show the properties of both metals
and non-metals. They are known as metalloids. Some common metalloids are arsenic,
antimony and silicon. The noble (inert) gases from the fourth category of elements.

The majority of the elements known to us are metals.For example gold, silver,
platinum, copper, iron aluminium, tin, nickel chromium, mercury, calcium, magnesium,
lithium, sodium, potassium, zinc, and many more.

Chapter 5: Coal and Petroleum

The prime necessities of human being are food, clothing and shelter. We need heat
energy to cook our food and other kinds of energy to run machines for manufacturing
articles of clothing and shelter. We use various materials to fulfill our energy
requirements which may be either natural or man made (i.e. artificial). We use the
resources of the earth in several other ways also.

Plants and animals are living natural resources while air, water and soil are non-living
natural resources. Fuel is a substance that can be used to produce heat at a
reasonable cost. Today fuels have become indispensable to man. Fuels are stores of
energy which on burning give heat and light mainly made up with carbon or its
compounds.

Chapter 8: Cell – Structure and Functions

The history of biology traces the study of the living world from ancient to modern times.
Although the concept of biology as a single coherent field arose in the 19th century, the
biological sciences emerged from traditions of medicine and natural history reaching
back to ayurveda, ancient Egyptian medicine. Cell form the basis of all living things.
They are the smallest single unit of life, from the simplest bacteria to blue whales and
giant redwood trees.

Differences in the structure of cells and the way that they carry out their internal
mechanisms for the basis of the first measure division of life, into the three kingdoms
of Archaea (ancient bacteria, Eubacteria (modern bacteria) and Eukaryota (everything
else, including us). An understanding of cell is therefore vital in any understanding of
life itself. Cell biology (formerly cytology, from the Greek ketos, "contain") is a scientific
discipline that studies cells – their physiological properties, their structure, the
organelles they contain, interactions with their environment, their life cycle, division and
death.

This is done both on a microscopic and molecular level. Cell biology research
encompasses both the great diversity of single-celled organisms like bacteria and
protozoa, as well as the many specialized cells in multicellular organisms such as
humans, plants, and sponges.Knowing the components of cells and how cells work is
fundamental to all biological sciences. Appreciating the similarities and differences
between cell types is particularly important to the fields of cell and molecular biology as
well as to biomedical fields such as cancer research and developmental biology.

These fundamental similarities and differences provide a unifying theme, sometimes
allowing the principles learned from studying one cell type to be extrapolated and
generalized to other cell types. Therefore, research in cell biology is closely related to
genetics, biochemistry, molecular biology, immunology, and developmental biology.

Chapter 9: Reproduction in Animals

The production of new organisms from the existing organism of the same species is
known as reproduction. Reproduction is the creation of new living beings. (From
existing living beings)It involves the transmission of genetic material from the parental
generation to the next generation. Process of reproduction is essential for existence
and continuity of a species. Types of Reproduction There are many ways in which new
organisms are produced from their parents. All the different ways of reproduction can
be divided in to two main groups such as asexual and sexual.

Chapter 10: Reaching the Age​of Adolescence

Adolescence is the period of physical and psychological development from the
childhood to adult. Before this period, the gonads of both the sexes are dormant. They
are stimulated by gonadotropins from the pituitary, which brings about the final
maturation of the reproductive system. Puberty-This is the period of sexual maturation.
Growth is a natural process. It begins from the day you are born, but upon crossing the
age of or 11,there is a sudden spurt in growth that becomes noticeable.

The period of life, when the body undergoes certain noticeable changes, leading to
reproductive maturity called adolescence. It begins after the age of 11 and lasts upto 8
to 19 years of age.Adolescents are also called as “teenagers” because the period
covers the teens (13 to 18 or 19 years of age). The human body undergoes several
changes during adolescence. These changes mark the onset of puberty. Puberty is the
start of the time when a boy is biologically ready to become a father and a girl is
biologically ready to become mother. It basically refers to the bodily changes of sexual
maturation rather than psychological and social transition from childhood to adulthood.
It generally overlaps the period of puberty. Puberty ends when an adolescent reaches
reproductive maturity.

The pituitary gland at this stage is highly active. In addition to it, the gonads also
become very active. The hormones secreted by the glands activate a series of
changes which bring in physical and mental development.During adolescence, there is
an increase in testosterone, changes in the ratio of excitatory and inhibitory
neurotransmitters and the physical restructuring of the brain.Around the age of 20, the
transmitters start to decrease and the inhibitory transmitters start to increase.

Thus, more adult-like personality traits emerge. Changes at Puberty: Increase in
Height-At this stage, the physical development takes place at a rapid pace. Specially at
the age of 13 in girls and 15 in boys, the development of height is the maximum.At this
time the long bones, that is the bone of the arms and the legs elongate and make a
person tall. By about 18 years of age, both girls and boys reach their maximum height.
The rate of growth in height varies in different individuals. Some may grow suddenly at
puberty and then slow down, while others may grow gradually. All parts of the body do
not grow at same rate.

Chapter 11: Forc​e and Pressure

Let us recall some of our everyday experiences. What do we do to open or close the
door of our home, to make a football move, to make a moving ball move faster? How
does a goalkeeper stop a ball?. Why school bags have wide straps? Why a sharp knife
cuts better than a blunt knife? Why a nail has a pointed tip? Why do buildings have
wide foundations? Why the rear wheels of tractors are made very wide? In day to day
life, we observe that some effort is required to put a stationary object into motion or to
stop it. So, to produce motion, the effort which is required is called as “Force”. In this
chapter, we will study about different concepts that revolve around “Force and
pressure”.you will learn Force, contact and non-contact forces, a force of friction,
pressure, pressure exerted by liquid and gases, and atmospheric pressure.

Chapter 12: Friction

On the atomic scale, even the most finely polished surface like steel is irregular, such a
surface can look plane to naked eyes but if seen under a powerful microscope, its
surface is found to be quite irregular. When two surfaces are in contact, the actual area
of contact is much less than apparent area of contact.In a particular case this area can
easily be in ratios of 1:104.At points of contact, the distance between the particles of
the two bodies becomes very small and their molecules exert very strong
intermolecular forces of adhesion on each other.As the actual area of contact is very
small, the adhesive pressure at the point of contact becomes very large.

Therefore many of the contact points may deform plastically.At these contact points,
molecular bonds are formed and these points become cold welded together.When one
body tens to move over the other, it involves rupturing of thousand of such tiny cold

welds.The cold welds continually reform as new contacts are made.This gives rise to
frictional force which resists the motion of one body over the other.

Laws of Friction: Friction can be operate between given pair of solids, between a
solid and a fluid or between a pair of fluids.But frictional force exerted by fluids is called
viscous force.

Friction can be classified on a basic of law of inertia.When two solid bodies slip over
each other, the force of friction is called kinetic friction.But when two bodies do not slip
on each other, the force of friction is called static friction.

“Frictional force applied on a body is directly proportional to the normal force acting
between the two bodies.

Chapter 13: Sound

Sound is a form of energy which makes us hear and travels in the form of waves.
Sound is produced by various sources. Though sound is mechanical in nature, its
perception is, of course, largely physiological.

Production of Sound: When you clap your hands, a sound is produced. In order
to know how sound is produced, let us perform the following two simple
experiments.
Experiment 1: Stretch a metallic wire AB between two nails fixed on a table as
shown in the figure. When we pluck the wire a sound is heard. If a V-shaped small
paper rider (R) is placed near the centre of the wire, it starts vibrating. If the rider
is placed at the centre of the wire, it flies off.
Experiment 2: On striking a bell B with a hammer, it produces sound. On touching
it with finger, we feel that the bell is in a state of vibration. 

In the above activities, we have produced sound by plucking and striking. We can also
produce sound by scratching, rubbing, blowing, shaking, etc. Thus, we conclude that
sound is produced by setting the objects in vibration. Vibration means a kind of rapid to
and fro motion of an object.

Propagation of Sound

The sound produced by vibrating objects reaches the listener only when it passes
through a medium which may be a liquid, a solid or a gas. Let us now briefly discuss
as to how sound travels from the source point of generation to the listener.

1. The vibration of the object sets the particles of the medium around it vibrating.
2. The particles do not travel from the vibrating object to the ear. A particle of the

medium in contact with the vibrating object is first displaced from its equilibrium
position as shown in the figure. This particle exerts a force on a neighboring
particle (2) which is displaced from its equilibrium position and also starts moving.
After displacing particle (2), particle (1) comes back to its mean position. This
process continues till the particle near the listener’s ear starts vibrating. Thus,
sound created by the source reaches the listener through the particles of the
medium without any net transport of the medium.

Chapter 16: Light

Light is a form of energy. More specifically, light is a general term commonly used to
refer to the "visible spectrum", which is the range of wavelengths, (and their
corresponding frequencies) that forms the visible part of the electro-magnetic
spectrum. The ranges in wavelengths vary from 380 nm to 750 nm. Each wavelength
corresponds to light of one particular colour so the "visible spectrum" range of
wavelengths would look something like the block below if each wavelength appeared
only once and they were all lined-up in order of increasing wavelength

The term "visible spectrum" means the range of electro-magnetic energy that most
people (i.e. those with "normal" vision) can see with the naked eye. This is just a small
part of a much wider range of energies, many of which we cannot see but some of
which are used in other ways, e.g. Radio Waves, Microwaves, Ultra Violet (UV) Light,
Infra-Red (IR) Radiation, X-Rays, and other wavelengths such as those used in many
different types of modern scanning equipment.

"White Light" is the way humans perceive and refer to our experience of receiving an
approx. equal quantity of all the wavelengths (i.e. colours) in the visible spectrum. This
explains why there are so many different "shades of white".

That is, when we see "white" we are receiving all the colors in approximately equal
amounts - but only approximately.

The combination of wavelengths (colors) received by our eyes usually contains a bit
more of some than of others, hence some "whites" can appear to be slightly "yellow",
some slightly "blue", and so on.

Just as white is not a "spectral color", neither is black or grey. White is the way we
perceive an approx. equal presence of all colours and black is the absence of
light/colour such that all colours/wavelengths are (equally) lacking. Shades of grey also
correspond to approximately the same amount of each colour, but in decreasing
amounts along a scale from white (lots of "light" energy in the form of many different
wavelengths, corresponding to different "colors", reaching the eye/brain) to black (no
"light" energy, that is an imperceptibly small quantity of "light" energy in the form of
many different wavelengths corresponding to different "colors" reaching the eye/brain).

Chapter 17: Stars and the Solar System

In this chapter, you will study galaxies, constellations, planets, and many more things.

Galaxy- A galaxy is a vast collection of stars, nebulae, and interstellar material
held together by gravity. Nebula is a cloud of dust and gas inside a galaxy, in
which a star is born.The smallest galaxies contain about 100,000 stars, while the
largest contain up to 3,000 billion stars. On the basis of shape, galaxies are
classified as irregular, spiral, and elliptical. E.g. (a) Irregular galaxy (b) Spiral
galaxy (c) Elliptical galaxy
Milky-Way Galaxy- We belong to a spiral-shaped galaxy called the Milky Way
galaxy. When you look up at the night sky, you can see a broad band of light in the
sky. This is formed by millions of faint stars that together form the Milky way
galaxy.
Light Year- Astronomers often measure distances in space in light years. A light
year is the distance travelled by light in one year.
Constellation- When you look at stars on a clear night, you can see some groups
of stars forming recognizable patterns. Such group of stars forming recognizable
patterns in the sky is called constellations. These are named after animals and
mythological characters.There are 88 constellations known so far. When any new
star is discovered, it is considered to be a part of the constellation it is closer to.
Some constellations that you can easily identify with the naked eye are Ursa
Major, Ursa Minor, and Orion.
URSA Major- This constellation consists of many stars arranged in a pattern
resembling a bear.Out of these stars, a group of seven stars constitute the
brightest and the most recognizable part of the Ursa Major. This group of seven
stars is called the Big Dipper or Vrihat Saptarishi. If these seven stars are joined
with imaginary lines, the figure obtained looks like a spoon with a long handle

Chapter 18: Pollution of Air and Water

Environmental pollution, solid, water & air pollution; chemical reactions in atmosphere,
kind of smog major atmospheric pollutant, acid rain, ozone and its reactions, effects of
the depletion of ozone layer, greenhouse effect & global warming, industrial and air
pollution, pollutants, green chemistry as an alternative tool for reducing pollution. The
population is defined as a group of organisms of the same species living in a
geographically localised area and capable of interbreeding among themselves.

In the entire universe, only planet earth has the unique gift of being endowed with a
wide variety of flora and fauna. This existence of life on the earth’s surface can be
attributed to various factors among which the abundant availability of water and air on
earth is the most important. The most common occurrence of water in liquid state, the
easy inter-conversion of this substance into different physical states and its
characteristic as a universal solvent and many other special features of this chemical
substance.

Air is a mixture of several gases. Water vapor and fine dust particles. A human being
respires about 22,000 times every day and takes in about 16kg of air.Air contains
mainly nitrogen, Oxygen and smaller amounts of argon, carbon dioxide, water vapors
and traces of helium, neon, krypton, and xenon.
