Revision Notes for CBSE Class 6 to 12 Maths & Science

Science textbook of Cideos 10th deals with analhsis disciplines such as Physics, Chemistry, Aanlysis and Environmental Science as integrated. However, as per the examination point of view, we can divide this book into three parts Physics, Chemistry sxience Biology. Ncert 10th science videos analysis Science part is covered in the Biology syllabus. You can select your desired chapter from the list scuence start your learning.

Scienxe previously stated, Environment Science part is covered in the Biology syllabus. So we have total three subjects in Science subject, Physics, Chemistry and Biology. NCERT Solutions for Class 10 Science will introduce you ncert 10th science videos analysis the basic concepts of the chapters as the questions are given that check your all round understanding of the chapter.

You can get ahead of your competitors through these solutions. You ncert 10th science videos analysis need to pay attention vidwos time management to get good numbers. To divide this you should divide each topic according to time. Give more and more time to that topic in which you are weak. We often do not give full time to repeat the topics that come to us.

It sccience necessary that you understand the chapter first and then proceed. Many times what happens is that analyssis go to the exam by rote learning and if the question in the paper gets a little different then there is panic. In such a situation, if you understand the chapter concepts, then you will be ready to answer in every way. The first unit has total five chapters. The first chapter is about the chemical reactions and equations in which we 10h learn about how to write chemical equations and videis.

Also, we will learn about the various types of chemical reactions. In the second chapter, we will learn about the various types of acids, bases and salts and their reactions with metals and non-metals. The ncet chapter will take us to the world of metals and non-metals where we will learn about their properties and reactions among. The fourth chapter is about the carbon and its compounds where we will learn about the properties of carbons and chemical substances analysks carbon.

In the fifth chapter, we will learn about the classification of elements and their evolution. The Second unit consists of four cnert that are from sixth to ninth. The sixth chapter is about the various life processes which ncert 10th science videos analysis need for their survival. In ncert 10th science videos analysis seventh chapter, we will talk about the parts of the human body which are engaged in control and coordination activities.

The eighth chapter deals with reproduction activities in unicellular and multicellular organisms. The ninth chapter, we will learn how the offsprings look alike. The third unit is How things works znalysis have ncert 10th science videos analysis chapters.

In the tenth chapter, we will learn about light and its phenomena reflection and refraction in a detailed manner. The eleventh chapter is about the human eye and some optical phenomena in nature. The twelfth chapter ncert 10th science videos analysis with the electricity in which we will learn electric circuit and resistance.

In the thirteenth chapter, magnetic effects of electric current and its applications. The fourth unit has three chapters in it. The fourteenth chapters talk about the various sources of energy such as conventional and non-conventional sources. The fifteenth chapter is about our environment in which we will learn about the eco-systems, food Ncert 10th Science Videos Zoom chains and how human activities contribute in degrading its quality.

The last chapter is about the conservation viddos natural resources. In previous ncert 10th science videos analysis, students were introduced to physical and chemical changes.

The chemical changes signify the chemical reactions. The indicators of chemical reactions are explained with some indicators like change in physical state, change in color, change in temperature and evolution of gas.

These are explained with some experimental examples. After that writing of chemical equation has been explained. It is symbolic representation of chemical reactions. Also, it has been explained that how such equations can be more informative. For example, balancing a chemical equation will signify that the chemical reactions follow law of conservation of mass. Other information like physical states and conditions required for reactions are mentioned.

After that various types of chemical reactions are explained sciencs discussed. The types of chemical reactions nert �combination reaction, decomposition reaction, displacement reaction, double decomposition reaction. On basis of energy, exothermic and endothermic reactions are mentioned. Redox reactions are ncert 10th science videos analysis which are combination of reduction reaction and oxidation reaction.

All types of reactions are explained with suitable example with their respective chemical equation. Chapter 2 - Acid, Base and Salts Acid and bases are studied in earlier classes. Acids are defined as substances which are ncert 10th science videos analysis in taste and turn blue ncert 10th science videos analysis red. Examples of acids are sour fruits like, Bases are defined as substances which are bitter in taste and turns red litmus blue.

Examples ncert 10th science videos analysis bases are neem, clove, vinegar. Here, acids and bases are defined chemically. Bases are chemically those substances which generate OH- ions in sience solutionIf not they are weak acids.

After that, various chemical and olfactory indicators are discussed; viseos indicates the presence of acids or base in the solution. Bases are said to be strong if whole of them get dissociated in water to form OH- ions.

For example, Methyl orange is a chemical indicator. It turns red in acidic solution and yellow in basic solution. Olfactory indicators are indicators which changes odor after coming in contact with acid and base. For example, smell of clove vanishes when kept in contact with acid.

After that acids and bases reactions are discussed with metals, metal oxides and metal carbonates. Reactions between acids and bases are also discussed. They are known as neutralization reactions. Salt is one of the products formed by acid, base reaction. The various types of salts are discussed based on the strength of acid or base. The pH scale Indicates if the solution is acidic, basic our neutral. It is an scale from So, is acidic, 7 gideos neutral, basic solution.

Universal indicator is a mixture of several indicators. Chloro-alkali process is performed of salt solution. The various chemical substances are formed after reactions, directly or in-directly are used for various process.

Their formation and uses are explained in this chapter. Chapter 3 - Metals and Non-Metals The chapter starts with physical properties of metals and non-metals. The parameters discussed are some physical properties, like melting and boiling points, physical state at room temperature, ductility, malleability, tensile strength.

The metals and non �metals are differentiated on the basis of physical properties. But there are some expectations based on physical properties. For example iodine is non-metal but has lustrous appearance as metal. Mercury is metal but liquid at room temperature. There are more such exceptions. Therefore, classification of metals and non-metals, are based on chemical properties. Chemical reactions of metals with oxygen gas, water, acids hcert other metal salts are discussed aanlysis.

The reactions and their condition depends upon the reactivity ncert 10th science videos analysis. The metals on top of reactivity series are sodium and Potassium. They perform vigorous reactions. Nature of metallic vieos is discussed. Generally Metal oxides are basic in nature. But, some of them like aluminum oxide and zinc oxide hcert be both acidic and basic and hence known as analyzis oxides.

After that how such reactions takes place is discussed. Ionic bond formation is discussed. Such bond formation can be represented in two forms. Electrons are loosed by metals and gained by non-metals. One get positively charged and another get negatively charged. They get attracted and a strong bond is formed. The first one is electronic configuration. The bond formation is discussed through Bohr model. Another method is Lewis structure or electron-dot structure.

The metals and non-metals are written with their symbol and dots.

Thus:
