Learn the nomenclature of Carbon and its compounds. The chapter deals with soaps and detergents and accounts for their cleansing actions towards the end. A total of fifteen questions are there in the chapter.

Chapter 5: Periodic Classification of Elements In this chapter, you will learn the arrangement of elements into the periodic table. The chapter starts with a brief history of modern periodic table and how and why we reached to it. It then goes on to describe the modern periodic table in detail.

Coming to the questions, there are ten questions in the chapter. The First two questions are of objective nature. In the last question, you need to state the differences between Mendeleev's Periodic Table and the Modern Periodic Table. Rest of the questions are of short answer type. There are total thirteen questions in the chapter of which first four questions are of objective type.

Chapter 7: Control and Coordination In this chapter, you will delve deeper into the topics such as nervous system of human beings, explanation about anatomy of the Human Brain, coordination in plant and hormones in animals. A total of 12 questions are there in this chapter. First three questions are of objective type. In the last two questions, you will be asked to differentiate between the given two topics.

Chapter 8: How do Organisms Reproduce This chapter explains the entire process of Reproduction for single-celled organisms as well as multi-celled organisms. It describes both asexual and sexual modes of Reproduction.

For sexual modes of reproduction, the reproductive systems of both animals and plants is explained. There is a total of eleven questions in this chapter.

First three questions are of objective nature. In the seventh question, you are asked to draw a labelled diagram of the longitudinal section of a flower. Remaining questions are of short and long answer type. Chapter 9: Heredity and Evolution In this chapter, you will learn how passing on of genes from one generation to another takes place. It also sex determination process after reproduction.

There is a total of 12 questions. The surface of some metals, such as iron, is corroded when they are exposed to moist air for a long period of time. This phenomenon is known as corrosion. Non-metals have properties opposite to that of metals. They are neither malleable nor ductile. They are bad conductors of heat and electricity, except for graphite, which conducts electricity. Non-metals form negatively charged ions by gaining electrons when reacting with metals.

Non-metals form oxides which are either acidic or neutral.

Non-metals do not displace hydrogen from dilute acids. They react with hydrogen to form hydrides. The maintenance of life requires processes like nutrition, respiration, transport of materials within the body and excretion of waste products.

Autotrophic nutrition involves the intake of simple inorganic materials from the environment and using an external energy source like the Sun to synthesise complex high-energy organic material. Heterotrophic nutrition involves the intake of complex material prepared by other organisms. 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.

During the process of respiration, complex organic compounds such as glucose are broken down to provide energy in the form of ATP.

ATP is used to provide energy for other reactions in the cell.

Respiration may be aerobic or anaerobic. Aerobic respiration makes more energy available to the organism.

In human beings, the transport of materials such as oxygen, carbon dioxide, food and excretory products is a function of the circulatory system. The circulatory system consists of the heart, blood and blood vessels.

In highly differentiated plants, transport of water, minerals, food and other materials is a function of the vascular tissue which consists of xylem and phloem. In human beings, excretory products in the form of soluble nitrogen compounds are removed by the nephrons in the kidneys.

Plants use a variety of techniques to get rid of waste material. For example, waste material may be stored in the cell-vacuoles or as gum and resin, removed in the falling leaves, or excreted into the surrounding soil.

Chapter 7: Control and Coordination Control and coordination are the functions of the nervous system and hormones in our bodies. The responses of the nervous system can be classified as reflex action, voluntary action or involuntary action. The nervous system uses electrical impulses to transmit messages. The nervous system 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. Chapter 8: How do Organisms Reproduce? Conventionally, the direction of current is taken opposite to the direction of flow of electrons.

The SI unit of electric current is ampere. To set the electrons in motion in an electric circuit, we use a cell or a battery. A cell generates a potential difference across its terminals. It is measured in volts V. Resistance is a property that resists the flow of electrons in a conductor. It controls the magnitude of the current. The resistance of a conductor depends directly on its length, inversely on its area of cross-section, and also on the material of the conductor.

The equivalent resistance of several resistors in series is equal to the sum of their individual resistances. One watt of power is consumed when 1 A of current flows at a potential difference of 1 V. The commercial unit of electrical energy is kilowatt hour kWh. Its one end, which points towards north, is called a north pole, and the other end, which points towards south, is called a south pole.

A magnetic field exists in the region surrounding a magnet, in which the force of the magnet can be detected. Field lines are used to represent a magnetic field. A field line is the path along which a hypothetical free north pole would tend to move.

The direction of the magnetic field at a point is given by the direction that a north pole placed at that point would take. Field lines are shown closer together where the magnetic field is greater. A metallic wire carrying an electric current has associated with it a magnetic field. The field lines about the wire consist of a series of concentric circles whose direction is given by the right-hand rule.

The pattern of the magnetic field around a conductor due to an electric current flowing through it depends on the shape of the conductor. The magnetic field of a solenoid carrying a current is similar to that of a bar magnet. An electromagnet consists of a core of soft iron wrapped around with a coil of insulated copper wire. A current-carrying conductor when placed in a magnetic field experiences a force.Still, have doubts or questions?

Its one end, which points towards north, is called a north pole, and the other end, which points towards south, is called a south pole. The extraction of metals from their ores and then refining them for use is known as metallurgy. Sample Papers. In this chapter, you will be learning different forms of energy available to us such as conventional and non-conventional sources of energy.

Acids and bases neutralise each other to form corresponding salts and water. In this chapter, you will learn the arrangement of elements into the periodic table.

Gradually in the chapter, refraction through a prism, refraction through atmosphere and Scattering of light have been explained. You need to keep practicing and revising your performance every day.
