The first chapter of Class 10 NCERT Science will teach the students about chemical reactions and how to write equations, how to conduct combination and decomposition reactions and more. In the previous classes, we have learned about physical and chemical changes in matter. Whenever a chemical change occurs, we can say that a chemical reaction has taken place. A complete chemical reaction represents the reactants, products and their physical states symbolically. Students will also study how to write a chemical reaction, which is a symbolic representation of a chemical reaction. The chapter also explains how various chemical equations can be balanced in different states.
In previous classes, students must have learned about various elements that can be classified as metals or non-metals on the basis of their properties. Here in Chapter 3 of Class 10 Science, students will learn about the physical properties of metals and non-metals. Metals are lustrous, malleable, ductile and are good conductors of heat and electricity. They are solid at room temperature, except mercury which is a liquid. The physical properties of metals are explained on various parameters such as ductility, malleability, tensile nature, strength, etc. On the basis of physical properties, metals and non-metals are differentiated. Some of the examples of non-metals are carbon, sulphur, iodine, oxygen, hydrogen, etc. The non-metals are either solids or gases except bromine which is a liquid. Under the subtopic chemical properties of metals, chemical reactions are discussed with oxygen gas, water, acids and other metal salts. The reactions and conditions depend on the reactivity series. The reactivity series tops potassium as the most reactive and gold as the least reactive.
Chapter 7 of Class 10 teaches about control and coordination, which are the functions of the nervous system and hormones in our bodies. The responses of the nervous system can be classified as a reflex action, voluntary action or involuntary action. The nervous system uses electrical impulses to transmit messages. It gets information from our sense organs and acts through our muscles. Chemical coordination is seen in both plants and animals. Hormones produced in one part of an organism move to another part to achieve the desired effect. A feedback mechanism regulates the action of the hormones.
In this chapter, we will learn about Heredity and Evolution. We have seen that reproductive processes give rise to new individuals that are similar, but subtly different. We have discussed how some amount of variation is produced even during asexual reproduction. The Rules for the Inheritance of Traits in human beings relate to the fact that both the father and the mother contribute practically equal amounts of genetic material to the child. This means that each trait can be influenced by both paternal and maternal DNA. Sex can be determined by different factors in various species. Changes in the non-reproductive tissues caused by environmental factors are not inheritable. Speciation may take place when the variation is combined with geographical isolation. Evolutionary relationships are traced in the classification of organisms. Tracing common ancestors back in time leads us to the idea that at some point in time, non-living material must have given rise to life.

This chapter of NCERT Class 9 Science students will teach about mixtures, solutions, properties of solutions, separation of mixtures, and physical and chemical changes. Along with this, they will also learn about compounds and their properties, the difference between mixtures and compounds, the classification of matter, etc.
This chapter deals with the classification of plants and animals. Students get to know that all living organisms are divided into 5 kingdoms namely Monera, Protista, Fungi, Plantae and Animalia. It also describes the classification and evolution, the hierarchy of classification.
This chapter talks about natural resources and their classification. It explains that coal, petroleum and natural gas are fossil fuels that are formed from the dead remains of living organisms millions of years ago. Then, it describes how coke, coal tar and coal gas are formed from coal. This chapter also describes the refining of petroleum. Further, the concept of natural gas is explained. The chapter ends by making students aware that natural resources are limited, so we should use them wisely.
