Chapter 1 – Chemical Reactions and Equations
Students will learn about chemical reactions, how to construct equations, how to conduct combination and decomposition reactions, and more in the first chapter of Class 10 NCERT Science. We have studied about the chemical and physical transformations of matter in earlier classes. We can refer to any change in composition that takes place as a chemical reaction. A full chemical process symbolically depicts the reactants, products, and their physical states. In addition, the art of writing a chemical reaction—a symbolic depiction of a chemical reaction—will be taught to the students. The chapter also describes the multiple states in which distinct chemical equations can be balanced.
The next subtopic includes a variety of examples and chemical reactions to teach about many types of reactions, including combination, decomposition, displacement, and double displacement processes. Exothermic and endothermic reactions are discussed in terms of energy. Reactions that release heat along with their products are called exothermic reactions; on the other hand, reactions that absorb energy are called endothermic reactions. The explanation of redox reactions follows, which are a combination of oxidation and reduction reactions. All types of reactions are explained in this chapter along with appropriate examples and the corresponding chemical equations.
Chapter 1 of Class 10 Science: Chemical Reactions and Equations Covered Topics
Chemical equations, balanced chemical equations, the implications of a balanced chemical equation, and the various types of chemical reactions—including oxidation, reduction, displacement, double displacement, precipitation, endothermic and exothermic processes, combination, decomposition, and displacement—are all discussed here.

Chapter 5 – Periodic Classification of Elements
We have learnt in Standard 9 that matter exists all around us in the forms of elements, compounds, and mixes, with elements consisting of atoms of a single type. When the elements were first classified, they were divided into two categories: metals and non-metals. Newlands provided the
Law of Octaves, whereas Dobereiner categorised the elements into triads. Mendeleev grouped the elements based on their chemical characteristics and ascending order of atomic mass. He even used gaps in his Periodic table to anticipate the emergence of several elements that have not yet been found. The periodic table as we know it now was created. The Modern Periodic Table was created using the atomic number as the foundation and amended Mendeleev’s Periodic Law.
The elements in the Modern Periodic Table are grouped in seven horizontal rows, or periods, and eighteen vertical columns, or groups, as described in this chapter, Periodic Classification of Elements. When elements are grouped in this way, they display periodic features such as metallic and non-metallic character, valency or combining capability, and atomic size. The quantity of valence electrons in an element’s outermost atomic shell determines its valency. The radius of an atom is referred to as its “atomic size.”

Chapter 6 – Life Processes
Chapter 6 of NCERT Science for Class 10 discusses Life Processes. Every living thing engages in six basic life processes. These include breathing, growing, reproducing, excreting waste, and feeding. The chapter also covers nutrition, which is the process of ingesting food and using it for metabolism, development, and repair. Ingestion, digestion, absorption, transport, assimilation, and elimination are the phases involved in nutrition. Heterotrophic and autotrophic nutrition are further subdivided under nutrition. Simple inorganic elements from the environment are consumed in autotrophic feeding, while complex, high-energy organic components are synthesised utilising an external energy source, such as the sun. Heterotrophic nutrition refers to consuming complex food that has been produced by another organism. Holozoic, saprophytic, and parasitic nutrition are three distinct forms of heterotrophic nutrition.
The subject of human nutrition will be covered next. Ingestion, digestion, oesophagus, stomach, small intestine, bile, absorption, assimilation, and egestion are the several stages of nutrition. The next subtopic is respiration, which provides a lovely explanation of the human respiratory system. The human respiratory system is made up of various parts, such as the lungs, bronchi, larynx, and throat. Organic substances like glucose are broken down to produce ATP, which is used as energy during respiration. The energy for subsequent processes in the cell is derived from ATP.
Aerobic or anaerobic respiration is possible. The organism has access to additional energy thanks to aerobic respiration. The closest and most abundant source of minerals, such as phosphorus and nitrogen, for plants is the soil. The circulatory system in humans is responsible for moving substances like food, oxygen, carbon dioxide, and excretory products. The blood, blood arteries, and heart make up the circulatory system. Water, minerals, food, and other elements are transported by highly specialised plants’ vascular tissue, which is made up of xylem and phloem. Nephrons in the kidneys of humans eliminate excretory products in the form of soluble nitrogen molecules. Plants eliminate waste using a multitude of methods.

Chapter 8 – How do Organisms Reproduce
Reproduction is not necessary, in contrast to other life processes, for an individual organism to survive. How Do Living Things The reproduce chapter describes how the cell that is participating in the process makes a copy of its DNA and adds more cellular machinery. Different species employ different techniques of reproduction depending on how their bodies are designed. Many bacteria and protozoa simply split into two or more daughter cells during fission. If an organism is split into fragments, it can regenerate, just like a hydra. They are also capable of producing buds that develop into new people. Through vegetative propagation, certain plants can produce new plants from their roots, stems, and leaves. These are instances of asexual reproduction, in which a single individual gives rise to new generations.
NCERT Solutions Class 10 Science Chapter 8: How Organisms Reproduce:
Reproduction: Both sexual and asexual reproduction occurs in plants and animals. reproductive health: family planning strategies and their need. HIV/AIDS versus safe sex. Having children and the health of women.

Chapter 9 – Heredity And Evolution
We shall study heredity and evolution in this chapter. Reproductive mechanisms have been shown to produce comparable but slightly different offspring. We have talked about how even in asexual reproduction, variety is produced to some extent. The idea that virtually equal amounts of genetic material are passed down to children from both parents is covered by the Rules for the Inheritance of Traits in Humans. This implies that both maternal and paternal DNA can have an impact on any given trait. In different animals, there are distinct factors that determine sex. Environmentally induced changes to non-reproductive tissues are not heritable. When variation is paired with geographic isolation, speciation may occur.

Chapter 10 – Light Reflection and Refraction
Using the straight-line propagation of light, we shall examine the phenomena of reflection and refraction in NCERT Class 10 Science Chapter 10. We can better understand some of the optical phenomena in nature by using these fundamental ideas. The chapter also covers light refraction and its practical applications, such as light reflection from spherical mirrors. Light is an energy source that gives humans the perception of vision. It appears like light moves in straight lines. Students learn about the two types of spherical mirrors: convex and concave. Ray diagrams are used to discuss the different terminology associated to spherical mirrors, such as focus, pole, radius of curvature, etc.

Chapter 11 – The Human Eye and Colorful World
Some of the properties of light were covered in the previous chapter. We shall examine a few of the optical phenomena found in nature in this chapter. The creation of rainbows and the division of blue and white light in the sky are also covered in this chapter. One of the most vital and delicate sense organs in the human body is the eye. We can see the beautiful world and the colours all around us thanks to it. The accommodation of the eye refers to its capacity to focus on both close and far objects by varying its focal length. The near point of the eye, also known as the least distance of distinct vision, is the minimum distance at which the eye can see objects clearly and strain-free.

Chapter 12 – Electricity
Modern society relies heavily on electricity. It is a practical and controllable energy source that may be used in a range of settings, including homes, businesses, schools, and hospitals. It is an occurrence connected to charge flow. An electric current is a stream of electrons flowing through a conductor. Traditionally, current flow is measured in the opposite direction to that of electron flow. Ampere is the SI unit of electric current. We utilise a cell or a battery to move the electrons in an electric circuit. A potential difference is produced between the terminals of a cell. Volts (V) are used to measure it. A conductor’s ability to thwart the flow of electrons is known as resistance.
It regulates the current’s strength. Ohm is the SI unit of resistance. According to Ohm’s law, if a resistor’s temperature doesn’t change, the potential difference across its ends is directly proportional to the current flowing through it. A conductor’s resistance is directly influenced by its length, inversely by its cross-sectional area, and also by the conductor’s substance. When many resistors are connected in series, their total resistance equals their equivalent resistance. W=V x I x t gives the electrical energy dissipated in a resistor. Watts is the unit of power (W). When 1 A of current flows at a potential difference of 1 V, one watt of power is consumed.

Chapter 13 – Magnetic Effects of Electric Current
Students will learn about electromagnetic phenomena such as magnetic fields in this chapter. They will also learn about electric generators, which use the electric effect of moving magnets, and electromagnets and electric motors, which use the magnetic effect of electric current. A little magnet is what a compass needle is. Its north pole is the end that points in that direction, and the south pole is the end that points in that direction. The area around a magnet has a magnetic field that allows one to measure the magnet’s force. A magnetic field is represented by field lines. A hypothetical free north pole’s natural course is called a field line. Where there is a stronger magnetic field, field lines are displayed closer together. A magnetic field is connected to a metallic wire that is conducting an electric current. The right-hand rule determines the direction of the concentric circles that make up the field lines surrounding the wire. The form of a conductor determines the pattern of the magnetic field that surrounds it when an electric current passes through it.
A solenoid that is conducting current has a magnetic field that resembles a bar magnet’s. A coil of insulated copper wire is wrapped around a soft iron core to form an electromagnet. A current-carrying conductor feels force when it is in a magnetic field. The force acting on the conductor will be perpendicular to both if the current and the field are both directed in the same direction. This force can be found using Fleming’s left-hand rule. This is how an electric motor works. An apparatus that transforms electric energy into mechanical energy is an electric motor.
The creation of induced current in a coil situated in an area where the magnetic field fluctuates over time is known as electromagnetic induction. The relative velocity of a magnet positioned close to the coil and the coil itself may cause changes in the magnetic field. When a coil is positioned close to a conductor that carries current, the magnetic field may shift as a result of the current flowing through the conductor or as a result of the coil and conductor moving relative to one another.
With Fleming’s right-hand rule, the direction of the induced current is determined. Electrical energy is produced from mechanical energy by a generator. Electromagnetic induction is the basis for its operation. Generators come in two varieties: AC and DC. The most crucial safety device is the fuse, which guards against overloading or short circuiting circuits.

Chapter 13: Magnetic Aspects of Electric Current
Magnetic effects of current include: force on current carrying conductor, Fleming’s Left Hand Rule, direct current, magnetic field, field lines, field due to a current carrying conductor, field owing to a current carrying coil or solenoid. AC frequency is known as alternate current. What makes AC better than DC. electrical circuits in homes.

Chapter 14 – Sources of Energy
Our standard of living rises along with our energy needs. We work to increase energy consumption efficiency and explore new energy sources in order to meet our energy needs. The chapter covers many energy sources, all of which are traditional energy sources that humans have been using for a long time. It consists of thermal power plants, hydroelectric plants, and fossil fuels. The benefits and drawbacks are also covered. Following those technological advancements, the use of traditional energy sources like wind and biomass is also covered. The subject of non-conventional or alternative energy sources will be covered by the students after this.
In NCERT Solutions Class 10 Science Among them is solar energy, which is produced by solar panels and solar cells. The ocean can produce various forms of energy, including wave, tidal, and thermal energy. Geothermal energy is another source of energy that can be produced from the earth’s crust. Energy found in an atom’s nucleus, or core, is known as nuclear energy. The energy source we choose will be determined by a number of criteria, including how simple and expensive it is to extract energy from the source, how effective the technology is for doing so, and how using the source will affect the environment. In the end, the Sun provides energy to a large number of the sources. Each issue is covered along with its benefits and drawbacks.

Chapter 15 – Our Environment
This chapter explores our interactions with the environment and how different elements work together. An ecosystem’s different parts are interrelated. The producers provide the rest of the ecosystem with sunlight energy. The number of trophic levels in a food chain is constrained by the energy lost as one moves up the trophic ladder. Using real-world examples from the forest, grassland, and pond, the food chain is thoroughly presented.
The environment is impacted by human activity. The ozone layer is in risk due to the usage of chemicals like CFCs. Since the ozone layer shields the Earth from solar UV radiation, this could be harmful to the ecosystem. We may produce biodegradable or non-biodegradable garbage. There are major environmental issues resulting from the way we dispose of the waste we produce.
