Standard 10th is the turning point in the life of every student who aspires to achieve something in his life. His devotion to work and a healthy foundation is the basis which can pave his road to success. At this age, he has to decide upon his interest to choose what suits him the best and which will prove to be the best for his nearing future. Some may want a stream because of passion or to follow their dreams; some maybe because of family pressure for a particular direction and imitating their peers.

Whatever happens, whether it's out of interest or imposition, one has to pursue the best from it because it is the deciding factor for the future waiting for our arrival. We need to make our subjects strong so that we don't regret later that a little bit of extra effort might have proven useful.

In this article, I will be putting light on the subject, which is the basis of all without any stream distinction. The course loved by many, the one with the play of numbers that is . This is the subject which nurtures us from the very beginning of our school life and continues till ages.

Science of standard 10th is developed based on the foundation in class 9th. Standard 10 Science is quite the core for the students who are planning to pursue Engineering or any statistics field. Scoring good marks in the board exam may develop a great taste and foundation for this subject.

To achieve success in any exam, NCERT 10th Science plays a vital role. All the concepts frequently asked in competitive exams are thoroughly covered. The topics are explained elegantly with simple steps and innovative approaches.

This book is written by content experts on the standard 10thScience CBSE syllabus. Most of the boards recommend NCERT as a religious book for their studies. They are helpful to candidates who aspire to score good and easily crack competitive exams.

The way of presenting the content is quite beautiful as it is quite a student-friendly. The contents start from the very basics and go till the most difficult.

Now coming onto the syllabus covered in the book, which every standard 10thstudent should be well acquainted with.

The Topics included are:

• Chemical Substance – Nature and Behaviour
• World of Living
• Natural Phenomena
• Effects of Current
• Natural Resources

Unit I: Chemical Substances – Nature and Behaviour

• Polynomials : Chemical equation, Balanced chemical equation, implications of a balanced chemical equation, types of chemical reactions: combination, decomposition, displacement, double displacement, precipitation, neutralization, oxidation, and reduction.
• Acids, Bases, and Salts : Their definitions in terms of furnishing of H+ and OH– ions, General properties, examples, and uses, the concept of pH scale (Definition relating to logarithm not required), the importance of pH in everyday life; preparation and uses of Sodium Hydroxide, Bleaching powder, Baking soda, Washing soda and Plaster of Paris.
• Metals And Nonmetals : Properties of metals and nonmetals; Reactivity series; Formation and properties of ionic compounds; Basic metallurgical processes; Corrosion and its prevention.
• Carbon Compounds : Covalent bonding in carbon compounds. Versatile nature of carbon. Homologous series. Nomenclature of carbon compounds containing functional groups (halogens, alcohol, ketones, aldehydes, alkanes, and alkynes), the difference between saturated hydrocarbons and unsaturated hydrocarbons. Chemical properties of carbon compounds (combustion, oxidation, addition, and substitution reaction). Ethanol and Ethanoic acid (only properties and uses), soaps, and detergents.
• Periodic Classification of Elements : Need for classification, early attempts at classification of elements (Dobereiner's Triads, Newland's Law of Octaves, Mendeleev's Periodic Table), Modern periodic table, gradation in properties, valency, atomic number, metallic and non-metallic properties.

Unit II: World of Living

• Life processes : 'Living Being.' The basic concept of nutrition, respiration, transport, and excretion in plants and animals.
• Control and Co-Ordination In Animals And Plants : Tropic movements in plants; Introduction of plant hormones;
• Control and Co-Ordination In Animals : Nervous system; Voluntary, involuntary, and reflex action; Chemical Co-Ordination: animal hormones.
• Reproduction : Reproduction in animals and plants (asexual and sexual) reproductive health-need and methods of family planning. Safe sex vs. HIV/AIDS. Childbearing and women's health.
• Heredity and Evolution : Heredity; Mendel's contribution- Laws for inheritance of traits: Sex determination: brief introduction; Basic concepts of evolution.

Unit III: Natural Phenomena

• Reflection of light by curved surfaces; Images formed by spherical mirrors, center of curvature, principal axis, principal focus, focal length, mirror formula (Derivation not required), magnification.
• Refraction; Laws of refraction, refractive index. Refraction of light by the spherical lens; Image formed by spherical lenses; Lens formula (Derivation not required); Magnification. Power of a lens.
• The functioning of a lens in the human eye, defects of vision and their corrections, applications of spherical mirrors and lenses. Refraction of light through a prism, dispersion of light, scattering of light, applications in daily life.

Unit IV: Natural Recourses

• Sources Of Energy: Different forms of energy, conventional and non-conventional sources of energy: Fossil fuels, solar energy; biogas; wind, water and tidal energy; Nuclear energy. Renewable versus non-renewable sources of Energy.
• Our Environment: Eco-system, Environmental problems, Ozone depletion, waste production and their solutions. Biodegradable and non-biodegradable substances.
• Management Of Natural Resources: Conservation and judicious use of natural resources. Forest and wildlife; Coal and Petroleum conservation. Examples of people's participation for conservation of natural resources. Big dams: advantages and limitations; alternatives, if any. Water harvesting. Sustainability of natural resources.

All the chapters are well covered, and the student can thoroughly revise all the above topics quickly. They include real-life examples and questions which help `us to build our mind and shape it accordingly.

Students must deeply go though all the subtopics mentioned above as these are not only helpful for scoring in boards but also in competitive exams like NTSE.

There is one supplementary book with NCERT 10th Science that is the Science exemplar. This is an excellent book that has Multiple Choice Questions (MCQ) and subjective ones too. These two books are the one which paves your way for a glorious success.
