CBSE NCERT solutions for class 10 science chapter 5 Periodic Classification of Elements: The matter around us is present in the form of elements, compound or mixture. There are 118 elements found till today and all these elements have different properties. Classification makes it easier to learn about them and our focus in this chapter should be to understand how the classification works. The classification is very important to study the physical and chemical properties of all elements. So, scientists have arranged all elements in certain rows and columns based on their properties and created the periodic table. This chapter will cover the history of the periodic table starting from Dobereiner's Triads to the modern periodic table, properties, and trend of elements in the modern periodic table. This chapter is the most important chapter of CBSE NCERT class 10th science as it is very useful in class 11th and 12th.
NCERT solutions for class 10 science chapter 6 Life Processes: How do we differentiate if someone is alive or not? Generally by the visible movements like running, shouting, or breathing. However, some animals breathe in such a manner that it is not visible to the naked eye. Then how we can identify who is alive? In this chapter, you will get answers to all these questions and more. The invisible molecular movement is necessary for life. Life process involves various activities by the digestive system, respiratory system, and circulation system performed by the living organisms to sustain their living. Solutions of NCERT for class 10 science gives you the answers to various questions like how organisms obtain their nutrition to stay alive, what is life and its processes, what is nutrition for human beings and plants and how it works.
Solutions of NCERT class 10 science chapter 7 Control and Coordination: In the previous chapter you have learnt about life process and how molecular movement is necessary to stay alive. But we make these movement responses to the environment in a controlled manner. All living organisms has a control and coordination system.In multicellular organisms, specialized tissues are used tocontrol and coordinate. Here, you will study this control and coordination system, nervous system, the human brain, coordination in the plant, hormones in animals, etc.
CBSE NCERT solutions for class 10 science chapter 8 How do Organisms Reproduce: Reproduction is a biological process by which new individual organisms are born from their parents. It involves creating a new DNA copy and other cellular apparatus. Reproduction is not an essential process for sustaining the life of an individual. Each individual organism exists because of reproduction. It is a fundamental feature of all known life. In this chapter, you will study reproduction, how it takes place, why it is necessary for the living organisms, and what are the different modes of reproduction in single organisms, sexual reproduction in flowering plants, sexual reproduction in human beings, etc. Terms like fission, fragmentation, regeneration, budding, vegetative propagation, and spore formation are also explained with examples.

Solutions of NCERT class 10 science chapter 10 Light Reflection and Refraction : We see a variety of objects around us in everyday life. We are able to see objects in the presence of light but we can't see them in the dark. What makes the object visible? When a reflected light from an object is received by our eyes we are able to see the object. In this chapter, you will study the phenomena of reflection and refraction of light using the straight-line propagation method. These basic concepts will help you in the study of some of the optical phenomena in nature.

It can be converted from one form to another. This chapter will tell you about the different sources of energy like conventional and non-conventional.
Fossil fuels, thermal power plant, hydropower plant, Bio-mass, wind energy are examples of conventional sources of energy. Solar energy, tidal energy, wave energy, ocean thermal energy, geothermal energy, nuclear energy are examples of non-conventional sources of energy. You will also get to know the environmental consequences of energy.
NCERT solutions for class 10 science chapter 15 Our Environment: The change in the environment affects us, our activity changes the environment around us, as we are an integral part of the environment.

In this chapter, you will also learn about the ozone layer and how it is getting depleted. Managing the garbage that we produce, how we impact the environment are other topics we will learn here.
Solutions of NCERT for class 10 science chapter 16 Sustainable Management of Natural Resources: You must have heard the famous phrase in Sanskrit ‘Vasudhaiv kutumbakam’ which means “the entire earth is one family”. The phrase is found in ‘Maha Upanishad’, an ancient Indian text in Atharva Veda. Living in harmony with nature is in our culture, tradition, and philosophy. In CBSE NCERT class 9 science you have learnt about natural resources like soil, air, and water while in the previous chapter, you have learnt about these resources have been polluted. In this chapter, you will learn how you ought to use these natural resources and sustain them for our future.
