Class 8 Science Solutions and Main Points for NCERT Books

Chapter 1: Crop Production and Management

In Class 8 Science Chapter 1, we will study about Agricultural Practices. More about Rabi and Kharif Crops and preparation of soil – ploughing using Plough, Hoe and Cultivator. Here, we will learn about sowing with traditional as well as modern tools. Chapter 1 of 8th Science, describes the use of Manure and Fertilisers on crops and the methods of replenishing the nutrients of soil through crop rotation. Use of irrigations and their methods, protection from weeds and use of weedicides given properly.

Chapter 2: Microorganisms: Friend and Foe

In Class 8 Science Chapter 2 we will learn about microbes. Do you know? Microbes can be classified into four major groups – bacteria, fungi, protozoa and some algae. Viruses are also known as Microscopic Organisms but they reproduce only inside the cells of the host organism. Common ailments like cold, flu and most coughs are caused by viruses. Serious diseases like polio and chickenpox are also caused by viruses. Corona [COVID – 19] viruses also have made a disaster in all over the world. Harmful microbes cause or spread diseases whereas useful microbes also which are helpful for the environment as well as for the living of Human beings.

Chapter 3: Coal and Petroleum

In Class 8 Science Chapter 3 starts with the intro of Inexhaustible Natural Resources and Exhaustible Natural Resources. We have to study deeply about Coal, means formation, users and availability everything including Coal Gas, Coal Tar and Coke.

Mining and refining of Petroleum is also an interesting topic in Chapter 5 of Grade 8 Science. Natural Gas – CNG is also an important topic to study for exams. These all are natural resources and limited in quantity. So, we should use natural resources carefully and wisely.

Chapter 4: Combustion and Flame

In Class 8 Science Chapter 4 we will study about Combustion. Every combustion needs fuel. Do you know that the substance that undergoes combustion is said to be fuel (combustible)? Combustion of materials needs the oxygen and ignition temperature. The minimum temperature required to burn a substance is known as Ignition temperature.

The substances which have quite a low ignition temperature, they can easily catch fire with a flame. So, these are called inflammable substances. We should be careful about such substances and keep it away from the flame. Sometimes a material suddenly bursts into flames, without the application of any apparent cause, this is called spontaneous combustion.

Chapter 5: Conservation of Plants and Animals

In Class 8 Science Chapter 5, we will study about deforestation and its causes. Do you know that due to human activities the fertile land gets converted into deserts? It is called Desertification. We should more about Wildlife Sanctuaries, National Parks and Biosphere Reserve.

As we know that the plants and animals found in a particular area are termed flora and fauna for that area. So, we should preserve our flora and fauna. We should be more careful and protective about Endemic species, which are found exclusively in a particular area. We should know more about Endangered Animals whose numbers are diminishing to a level that they might face extinction.

Chapter 6: Reproduction in Animals

In Class 8 Science Chapter 6, we will study about the mode of reproductions like Sexual Reproduction and Asexual Reproduction. In sexual reproduction, male and female reproductive organs get involve. The male gamete is known as sperm and the female is known as ova. After the fertilisation, the zygote is formed with later on converted into an embryo. When, in embryo, all the body parts can be identified, now it is called a foetus. Budding and fission are common ways to generate the new young one in asexual reproduction.

Chapter 7: Reaching the Age of Adolescence

In Class 8 Science Chapter 7 we are going to discuss the period of life, when the body undergoes changes, leading to reproductive maturity, is called adolescence. normally the adolescence starts from the age of 11 and lasts up to 18 or 19 years of age. This period covers about thirteen to nineteen years of age, that is why adolescents are also called ‘teenagers’. The period of adolescence may vary from one person to another. At the age of puberty, there may observe the increase of height, change in voice, change in body shape and development of sex organs. In females, the reproductive phase of life begins at puberty and generally lasts till the age of approximately 45 to 50 years.

Chapter 8: Force and Pressure

In Class 8 Science Chapter 8 we are going to know about the terms related to forces and pressure. We know that any push or pull on an object can be treated as a force. The interaction between two objects results in a force between the two objects. If the forces applied on an object in the same direction, the net force can be obtained by adding one another whereas if the two forces act in the opposite directions on the object, the net force acting can be calculated by subtracting them. The strength of a force is known as the magnitude of the force. A force may bring a change in the state of motion, shape or position of an object.

Chapter 9: Friction

In Class 8 Science Chapter 9 we will learn about the force of friction and the factors which affect the friction. We know that friction is a necessary evil. It reduces the force but it is useful in most the actions. A moving object would never stop if there were no friction. The substances which reduce friction are called Lubricants. In some machines, it may not be advisable to use oil as a lubricant. We can reduce friction by putting an air cushion between the moving parts. Rolling of one body over the surface of another body, the resistance to its motion is called Rolling Friction. The frictional force on an object in a fluid depends on its speed in the fluid, the shape of the object and the nature of the fluid.

Chapter 10: Sound

In Class 8 Science Chapter 10 we have to study about sound and its characteristics. We will know here about vibration and devices which produce vibrations. We can produce a different type of sound with the help of the vocal cord. All the sound produced by a human is just because of the vibration of vocal cords. Sound always requires a material medium to propagate. Different sounds can be identified by their loudness, shrillness, pitch, etc., properties. Eardrums help us to hear all type of sound. The characteristic of sounds can be known by its frequency, amplitude, wavelength, speed and time periods.

Chapter 11: Chemical Effects of Electric Current

In Class 8 Science Chapter 11 we will try to know about different terms related to electricity. A substance may be termed as a good conductor or bad conductor depending on whether the current can flow through it or not. When we cover a metallic substance with another using electrolysis, it is called electroplating. It is useful to prevent the metallic substance from corrosion also.

Chapter 12: Some Natural Phenomena

In Class 8 Science Chapter 12 deals the activates known as Natural Phenomena. We all have seen the lightning and heard the thundering during the rainy season. The chapter starts with the concepts of charging and the types of charges as negative and positive. When two charged objects come close to each other, the transfer of charges takes place. Using electroscope, we can check whether an object is charged or not. It also describes the strength of charge. We must know the dos and don’ts during the thunderstorms or earthquake.

Chapter 13: Light

In Class 8 Science Chapter 13 we will study about light, visibility of objects due to light and laws of reflection. During the study about light, we should know about Incident Ray, Reflected Ray, Normal at the point of incident. The first law of reflection states that angle of incidence is always equal to the angle of reflection. According to second law of reflection, the incident ray, the normal at the point of incidence and the reflected ray all lie in the same plane. Terms lateral inversion, dispersion, diffusion and regular reflection are also important for exams. Multiple image of an object due to multiple reflection can be seen in Kaleidoscope. At the end of the chapter, structure of eye, defects of eyes and Braille system of writing is given as important part of chapter 13 of Grade 8 Science.

Science is interconnected with other subjects like mathematics, technology, and engineering. A solid scientific foundation enhances students’ abilities in these related fields. Science ignites curiosity and wonder about the natural world. It encourages individuals to explore, question, and seek answers to the mysteries of the universe.
