We have to learn about Periodicity which is the properties including atomic size, valency as well as combining capacity and metallic and non-metallic character. Life processes include the main four processes like Nutrition, Digestion, Respiration and Excretion. We know that maintenance of life requires these processes to transport of materials within the body and excretion of waste products.
Autotrophic nutrition and Heterotrophic nutrition both describe separately. In human beings, the food eaten is broken down by various steps along the alimentary canal and the digested food is absorbed in the small intestine to be sent to all cells in the body. Respiration may be aerobic or anaerobic. Aerobic respiration releases more energy as compared to anaerobic.
In human beings, excretory products in the form of soluble nitrogen compounds whereas in plants gum and resin. Control and coordination, in Class 10 Science, have the functions of the nervous system and hormones in our bodies.
The responses of the nervous system as a reflex action, voluntary action or involuntary action. Functions of sensory and motor nerves. The nervous system uses electrical impulses to transmit messages using neurons. Chemical coordination in plants using various hormones.
Effect of hormones and related glands in human. The action of the hormones is totally based on a feedback mechanism. Class 10 Science Chapter 8 involves the creation of a DNA copy and additional cellular apparatus by the cell involved in the process and different modes of reproduction depending on their body design. For example, in fission, many bacteria and protozoa simply divide into two or more daughter cells, whereas organisms such as hydra can regenerate if they are broken into pieces.
Roots, stems and leaves of some plants grow to be new plants through vegetative propagation. Sexual Reproduction is totally different from Asexual Reproduction. Sexual reproduction involves two individuals for the creation of a brand new individual.
Reproduction in flowering plants involves the transfer of pollen grains from the anther to the stigma which is referred to as pollination. Sexual reproduction in human beings involves the introduction of sperm to fertilisation occurs in the fallopian tube. Variations arising during the process of reproduction can be discussed in Chapter 9 Heredity and Evolutions of Class 10 Science.
As we know that sexually reproducing individuals have two copies of genes for the same trait. Concepts of dominant trait and recessive trait traits describe the transfer of traits properly in this chapter.
Difference between inherited and acquired traits are the important topics which are frequently asked in Boards. The determination of sex of the offspring depends on different factors in all species. All the variations during the reproductions in the species somehow confer survival advantages. Sometimes it also shows the genetic drift. Due to geographic isolation, the speciation of species takes place. The concepts given in Light chapter are also important for further classes. The straight-line path of light and mirror � lens application is given for study.
We have to study the reflecting surfaces, of all types, obey the laws of reflection and the refracting surfaces obey the laws of refraction. Main topics are New Cartesian Sign Conventions, mirrors and lenses formula, focal length, the radius of curvature and magnification. The power of a lens is measured as the reciprocal of its focal length. Its SI unit is dioptre. After going through Chapter 11 of Class 10 Science, we will be able to know about the accommodation of the eye, the near point of the eye or the least distance of distinct vision.
The common defects of vision, which are included in Class 10 Science Chapter 11, are myopia, hypermetropia and presbyopia.
We will study here how to form a Rainbow or why we see sky reddish in the morning or evening. The blue colour of the sky and the reddening of the Sun at sunrise and sunset is due to scattering of light. We will deal here with the basic concepts of Electricity and its heating effects.
We know that a stream of electrons moving through a conductor constitutes an electric current. But, conventionally, the direction of current is taken opposite to the direction of flow of electrons. In Chapter 12 of Class 10 Science , we will learn about the SI unit of electric current, use of a cell or a battery and use of voltmeter and ammeter.
Concepts of resistance and resistivity are also new for class 10 students, but these are important terms for further classes. Here we learn how to find total resistance when they are attached in parallel or series.
The unit of power, consumption of electricity with heating effect and commercial unit of electricity are also important for exams. Here we will learn about a compass needle which is a small magnet and its one end, which points towards north, is called a north pole, and the other end, which points towards the south, is called a south pole. Main topics are Magnetic field, the direction of the magnetic field and a metallic wire carrying an electric current has associated with it a magnetic field.
We know that an electromagnet consists of a core of soft iron wrapped around with a coil of insulated copper wire. Here we have to study about Magnetic field of a solenoid carrying a current with a comparison of a bar magnet. An electric motor and the phenomenon of electromagnetic induction are also important for exams.
Questions are frequently asked on the basis of a generator, live wire, fuse, short-circuiting or overloading. As we know that our energy requirements increase with our standard of living nowadays.
For our energy requirements, we have to improve the efficiency of energy usage and also try and exploit new sources of energy. In Chapter 14 of Class 10 Science, we will learn how we are looking for new sources of energy because the conventional sources of energy like fossil fuels are in danger of getting exhausted soon.
Here, we will also learn about some solar devices and their advantages and disadvantages. All the energy sources depend on various factors like the ease and cost of extracting energy from the source. Solar cells, solar cooker, windmills, etc. The various components of an ecosystem are interdependent. We know that the producers make the energy from sunlight available to the rest of the ecosystem. Food web or food chain is based on producers.
The ozone layer is now affected due to excess use of CFCs. The generated waste may be biodegradable or non-biodegradable cause the problem of disposal. In Chapter 16 of Class 10 Science , we will learn how to use our natural resources like forests, wildlife, water, coal and petroleum in a sustainable manner. We know that fossil fuels like coal and petroleum will ultimately be exhausted after a few years. In this chapter, we will learn how to utilise the renewable resources which may last for many years.
Important derivations, numerical problems, practice test and assignments will also have uploaded time to time. To get updates, check the web page once a week or monthly. Through holiday homework page you can upload you summer holiday, if need help, we will provide the solutions and suggestions according to requirements.

Chapter 4: Carbon and its Compounds Chapter 4 of Class 10 Science, covers deals with versatile properties of carbon, Catenation and Tetravalency. Chapter 5: Periodic Classification of Elements Class 10 Science Chapter 5 is based on how elements are classified on the basis of similarities in their properties.
Chapter 7: Control and Coordination Control and coordination, in Class 10 Science, have the functions of the nervous system and hormones in our bodies. Chapter 8: How do Organisms Reproduce?
Chapter 9: Heredity and Evolution Variations arising during the process of reproduction can be discussed in Chapter 9 Heredity and Evolutions of Class 10 Science. Chapter Human Eye and Colourful World After going through Chapter 11 of Class 10 Science, we will be able to know about the accommodation of the eye, the near point of the eye or the least distance of distinct vision.
Chapter Electricity We will deal here with the basic concepts of Electricity and its heating effects. Chapter Magnetic Effects of Electric Current Here we will learn about a compass needle which is a small magnet and its one end, which points towards north, is called a north pole, and the other end, which points towards the south, is called a south pole. Chapter Sources of Energy As we know that our energy requirements increase with our standard of living nowadays.
Chapter Management of Natural Resources In Chapter 16 of Class 10 Science , we will learn how to use our natural resources like forests, wildlife, water, coal and petroleum in a sustainable manner.
Important Questions on 10th Science Why is respiration considered an exothermic reaction? Energy in our body is obtained from the food we eat. During digestion, large molecules of food are broken down into simpler substances such as glucose.
Glucose combines with oxygen in the cells and provides energy. The special name of this combustion reaction is respiration.
Since energy is released in the whole process, it is an exothermic process. What are olfactory indicators? Give an example. Olfactory indicators are substances which have different odour in acid and base solutions. For example, vanilla essence has characteristics pleasant smell in acid solution and no smell in alkali solution. Platinum, gold and silver are Ncert Solutions For Class 10th Hindi Surdas Lyrics used to make jewellery. Platinum, gold, and silver are used to make jewellery because they are very lustrous.
Also, they are very less reactive and do not corrode easily. Why are carbon and its compounds used as fuels for most applications? Most of the carbon compounds give a lot of heat and light when burnt in air. Saturated hydrocarbons burn with a clean flame and no smoke is produced. The carbon compounds, used as a fuel, have high calorific values.
