Chapter Wise Analysis Of NCERT Class 10 Science:
Chapter 1- Chemical Reactions and Equations:
The very first chapter of NCERT class 10 science is chemical reactions and refractions with its combination, decomposition and more. Chemical reaction introduces products, reactants and their physical states respectively. Students learn about how to write a chemical reaction with its products by balancing the equation in this chapter. With it students also learn about different chemical reactions such as decomposition reaction, combination reaction, displacement reaction and double displacement reaction with numerous examples of all chemical reactions for giving practical views. On energy related reactions endothermic energy represents the reaction where energy is absorbed and exothermic energy where heat is released along with produced materials. The redox reaction is another example which signifies oxidation reaction and combination reaction altogether. Students can find appropriate and sufficient examples of all types of chemical reaction with complete chemical equation.
Chapter 2- Acids, Bases and Salt:
NCERT class 10 science book describes acids, bases and salt in chapter 2. Students have learned earlier that sour and bitter tastes of food are due to the presence of acids and bases respectively. Students also know already that acids turns the blue litmus into red and base turns the red litmus into blue. They will learn further about chemical reactions between different acids and bases, how they break chemical effects and other important facts related to our daily activities. Students will learn about how both acids and bases reacts with metals, non-metals, reaction between metallic oxides and acids, reaction between hydrogen carbonates and acids with examples and chemical equations. They also get to learn that acid solution can conduct electricity in water which is proved by various experiments. Students also get the knowledge of pH and its effectiveness in every day’s life. It also explains detail analysis about salt preparation, its various properties and different usage.
Chapter 3- Metals and non-metals:
The 3rd chapter of NCERT class 10 science book provides information about metals, non-metals and its different purposes. Metals are malleable, lustrous and ductile for which they considered as good conductor of electricity and heat. All metals are solid at room temperature except mercury which is liquid in room temperature. The physical features of metals are explained from different dimensions like malleability, tensile, ductility and strength. Metals and non-metals are differentiated generally on physical properties. Various examples of non-metals are carbon, iodine, sulphur, hydrogen, oxygen etc. these non-metals appear either solids or gas except bromine which is liquid in room temperature. In the nature of reactivity, potassium is the most reactive element whereas gold is the least reactive element. The compounds formed by transforming electrons from a metal to a non-metal is known as ionic compound. The process in which metal is collected from its metal ores is known as metallurgy and then refined with the method electrolytic refining. Then students learn about corrosion and the possible ways to prevent it.
Chapter 4- Carbon and its compounds:
Chapter 4 of NCERT science book for class 10 constitutes the important facts of compound and their chemical properties. Students will learn about the significant element carbon in both of its combined and elemental form. For its versatile nature carbon formulates the base of many living organisms and other usable things of us. When electron is shared between two atoms of carbon that forms covalent bonds and create a totally full outermost shell. The covalent forms of carbon can be formed with its own atoms and other significant elements like sulphur, hydrogen, oxygen, nitrogen, chlorine etc. organic compounds are then classified in two groups such as saturated compounds and unsaturated compounds. Saturated carbon compounds are formed with a single bond where unsaturated compounds can be formed with double and triple bonds. Some examples of saturated compounds of hydrogen and carbon are ethane, methane, butane, propane, hexane and pentane. Students will also learn about different chemical properties of carbon like addition reaction, oxidation, and substitution reaction. Ethanoic acid and ethanol are two important carbon compounds which are useful in our daily life activities. The chemical properties of detergent and soap are also discussed with its differences and different purposes of usage.
Chapter 5- Periodic classification of elements:
Students have already studied that all matters are presented in the form of compounds, elements and mixtures which atoms can be one type for all cases. Earlier the elements have been grouped in metals and non-metals based on their chemical properties. Dobereiner categorized elements into triads and in this respect newland explained the law of octaves. In the modern periodic table Mendeleev arranged the elements sequentially in the periodic table according to their chemical properties and atomic masses in increasing order. He also depicted the possibility of some other elements discoveries to fill the gaps within periodic table. The law of Mendeleev’s periodic table has been modified where the atomic number of elements adopted for creating modern periodic table and the law of modern periodic table is the following: ‘properties of elements are a periodic function of their atomic number.’ Modern periodic table of Mendeleev has total 18 columns and 7 rows which are known as groups and periods respectively. Elements are presented in the table based on their different chemical properties like valency, atomic size, metallic character and non-metallic character. The valency of elements is structured by the number of total valence electrons that can be present in the outermost shell of an atom of that element.
Chapter 6- Life Processes:
Life processes is another important chapter of NCERT class 10 which students have to read with full concentration for understanding. Students will read about total six life processes which are growth, movement, respiration, nutrition, reproduction and excretion. The learning from this chapter also enhance knowledge about the importance of intake good nutritional food and its effect in the overall growth, development, metabolism and nutrition of the whole human body. Students will understand the complete nutritional value by studying its different stages like digestion, ingestion, transport, absorption, assimilation and excretion and their different effects on body. Students will read two types of nutrition which are autotrophic nutrition and heterotrophic nutrition. Autotrophic nutrition signifies having the simple inorganic food materials of the environment with the use of sun energy as an external source for synthesizing the high-energy organic food. Heterotrophic nutrition explains the intake of complex food materials which are combination of other organisms. Different types of heteroprophic nutrition are saprophytic nutrition, parasitic nutrition and holozoic nutrition. In the next topic respiration, the effectiveness of human respiration and the human respiratory system is discussed completely. The different parts of the human respiratory system are lungs, larynx, bronchi, pharynx etc. during the process of respiration compounds like glucose break down to form ATP which is used to produce energy for other reactions within cell.
Chapter 7- Control and coordination:
Chapter 7 of NCERT class 10 science book teaches about control and coordination which are the main functions of the nervous system and hormones of human body. There are different responses of the human nervous system which can be classified in two ways like reflex action, voluntary action and involuntary action. Electrical impulse is used within the entire nervous system for transmitting messages. The nervous system get informed about the senses from our all sense organs and then act accordingly with the muscles. The chemical coordination for responding to external sources can be seen in both cases of animals and plants. Hormones are produces in one part of human body which goes to another part of the body where is needed for fulfilling the desired effect. There works a definite feedback mechanism to regulate the formal actions of all hormones for humans and plants.
Chapter 8- How do organisms reproduce?
Chapter 8 of class 10 NCERT science book formulates the creation of DNA with additional cellular apparatus of the cell which is involved in the process. Different organisms adopt individual process of reproduction based on their body design and functionalities. In the process fission, bacteria and protozoa get divided into simpler forms of two or more multiple cells. Other organisms like hydra can regenerate if they break into multiple pieces. Plants reproduce through their different parts like leaves, stem, and roots from where new plants grow which is known as vegetative propagation. The process of plant reproduction is example of asexual reproduction in which new generation is created from a single individual. DNA based copy mechanism is important which creates variations for ensuring the survival of different species. The modes of sexual reproductions creates chances of greater variation among new generation which is generated from two animals. The process of reproduction in flowering plants occur through the transmission of pollen grains from one plant to the stigma of another plant which is known as pollination.
Chapter 9- Heredity and Evolution:
The chapter heredity and evolution of class 10 NCERT science is interconnected with the chapter reproduction. The rules of inheritance traits among human beings are directly related to the fact that both mother and father contribute almost equal amount of genetic material to their child. That means each inheritance trait is directly related to both paternal and maternal DNA. Though sex is determined by different factors of species still the changes in non-productive tissues by the environmental factors are not inheritable in those living species. Speciation takes place when the process variation combines with different geographical isolation. The relationship of evolution can be found in the organism classification. Finding out the common ancestors of past time generates the idea that in the back non-living substances have also contributed to the rising of life. Evolution can be explained completely with not only the functions of living species but also the different characteristics of non-living species like fossils. In the process complex organs have been evolved for the survival advantage even at the intermediate stages. During the process of evolution some new organs and features have also adapted to show new functions. Evolution cannot be described as the progress from low to high form rather it can be explained as the rising of complex body parts during the flourish of simpler body designs. The complete study of evolution spreads the idea that we all grow from the single species of Africa and move across all over the world.
Chapter 10- Light reflection and refraction:
The chapter 10 of NCERT class 10 science is significant one as it brings the knowledge about the phenomena light reflection and refraction based on the concept of light’s straight-line propagation. The basic concepts of light will be helpful for us to understand the optical phenomena presented in nature. Students will learn about the reflection of light through spherical mirrors, refraction of light and their application in real life experiences. We all know that light is the source of energy which creates the sense of vision among human beings. One of the most important function of light is that it travels through straight line. Students also get knowledge about different types of spherical mirrors like concave mirror, convex mirror and its importance in understanding the functions of light. The different terms related to spherical mirrors are also given like the radius of curvature, the centre of curvature, pole, focus etc. with specific ray diagrams. Mirror formula provide information about the relationship between image distance, object distance, and the focal length of mirror which is equal to half of its radius curvature. Refraction refers to the bending nature of wave during the entrance through a medium where its speed is different. When light moves from a fast medium to a slow medium the ray bends towards the normal boundary between the two media. Refraction of light can be understood easily with the concepts of optical density and refractive index. The formula of lens creates the relationship between image distance, object distance and focal length of spherical lens.
Chapter 11- The Human eye and Colourful World:
After learning about light and its properties in the previous chapter students will learn more about the optical phenomena that presented in the nature in this chapter of NCERT class 10 science book. Students will understand the various factors responsible for formation of rainbow, splitting of blue light in the sky and splitting of white light in this chapter. The eyes are one of the most important human organs which enables us to see the beautiful world and different colours around us. The specific ability of the eyes to see nearby and distant objects by adjusting their focal length is known as the accommodation of the eye. The smallest distance from which eyes can see objects clearly is referred to the least distance of distinct vision which can be 25 cm for a normal person. The common refractive defects of visions that found among humans are hypermetropia, myopia and presbyopia. Myopia is the defect of short sightedness when the image of distant object is focused before the retina get corrected with the use of concave lens having suitable power. On the other hand, hypermetropia can be corrected by using convex lens of suitable power though the eyes generally loses in natural power of accommodation at the old age. The splitting of white light into its different component colours is known as dispersion. Scattering of light is the responsible reason for the blue colour of sky, redness during sunrise and sunset.
Chapter 12- Electricity:
The next chapter of NCERT class 10 science is about the important component of electricity which has great impact in our society. Electricity is the convenient and controllable form of energy which is applicable to various uses like homes, hospitals, schools, industries etc. the phenomenon electricity related to the flow of charge in which a stream of electric current moves through a conductor and produces electric current. In conventional form, the direction of current goes opposite to the flow of electrons. The SI unit of electric current is ampere. We use battery or cells for setting up the electrons in perfect motion within an electric circuit. Resistance refers to the property which resists the natural flow of electrons in conductor and its SI unit is Ohm. The ohm’s law explains that the potential difference at the end point of resistor is directly proportional to the current moves through it and its provided temperature remains the same. The resistance of a conductor generally depends on its length and inversely on the cross-section areas on the material of conductor.
Chapter 13- Magnetic Effects of Electric Current:
In the chapter of magnetic effects of electric current in class 10 NCERT science provides complete knowledge. It is about various magnetic fields like electromagnetic effects with its specific electric motors and electromagnets which includes magnetic effect of electric current and electric based generators which works on the electric effects of moving magnets. A compass is a small magnet where the north end is known as North Pole and southern end is known as South Pole. The magnetic field is called the entire area surrounded a magnet in which the force of magnet works effectively. Field lines are used for referring the magnetic field. Field lines are presented closer together where the magnetic field is greater. The field lines of a wire consist of a series with same concentric circles and its direction is presented according to the right hand rule. The specific pattern of the magnetic field all around the conductor is due to the electric current goes through it which depends on the present shape of the respective conductor. Electromagnetic induction refers to the production of induced current within a coil which is placed in the magnetic region where the magnetic field can be changed with time. The magnetic field may be changed for the relative motion between the magnet and the coil placed into the coil. The overall understanding of the entire chapter gives a complete view about magnetic field and its application in the real life experiences.
Chapter 14- Sources of energy:
In chapter 14 students will learn about the most significant factor of life that is sources of energy. We all know that the requirements of energy is gradually increasing with the developed standard of living. For fulfilling the energy requirements, scientists are constantly working on improving the energy efficiency of conventional energy resources, trying to extending and exploiting the new and renewable sources of energy. The chapter gives complete description about the various conventional sources of energy like fossil fuels, hydropower plants and thermal power which have been using for so long. Constant usage of these conventional sources have numerous advantages and disadvantages which are affecting the environment overall and making our future insecure. For keeping the balance in nature various renewable energy resources have been started after researching its functionalities like solar energy, wind energy and biomass. With advanced research and technology solar energy is now applied to various places through establishing effective solar panels and solar cells. Energy is also generated from the sea water which is known as tidal energy, ocean thermal energy and wave energy. Energy is also started producing from the earth’s crust and that is called geothermal energy. With advanced technology in nuclear reactions nuclear energy is also produced greatly from the nucleus of an atom. The main advantage of the non-conventional and renewable sources of energy is that it is friendly in nature towards the environmental and people can use it extensively.
Chapter 15- Our Environment:
The 10 chapter of NCERT class 10 science gives knowledge about the different components of the environment which interacts with one another and their overall impact on the environment. All the components within the environment are interconnected and interdependent which creates the ecosystem with vast characteristics. The producers absorbs the energy of sun to produce food which then transmits to the rest living organisms of the ecosystem. There is a loss of energy in each trophic level of 10% as we go to the upper level from the producers. The interconnectedness of different living organisms and animals creates the food chain which is described in different areas individually like forests, sea and land. But the human activities leaves a major impact on the environment nowadays which creates the imbalance in nature. The use of CFCs in refrigerators, ac and other machines endangered the most important ozone layer presented in the atmosphere. For that the harmful ultraviolet rays of the sun enters the earth easily and causes skin damage and eye problems among human beings. The degradable and bio-degradable waste materials are the reasons of serious environmental problems which affects us.
Chapter 16- Sustainable management of natural resources:
In the previous chapters of NCERT science book class 10 students have learned about different natural resources like soil, air and water which are recycling over and over again for future use. In the present chapter sustainable management of NCERT class 10 science students will study the natural resources deeply and their usage for different purposes. All the natural resources that we have like forests, water, coal, petroleum and wildlife need to be used wisely in a sustainable manner. We can maintain the balance in the environment effectively by following the pattern refuse, reuse, reduce, recycle and repurpose sincerely. Various stakeholders have now focused in protecting the forest resources with sustainable management program. For managing water resources multiple projects have been applied for building dams which will improve the entire social, environmental and economic life implications. The local promotion has been arising for awakening the local people to save their local environment with small contribution. The conventional resources like fossil fuels, petroleum and coal will be ended one day for which its combustion and usage need to be controlled to keep the balance in nature.
