As previously stated, Environment Science part is covered in the Biology syllabus. So we have total three subjects in Science subject, Physics, Chemistry and Biology. The first unit has total five chapters. The first chapter is about the chemical reactions and equations in which we will learn about how to write chemical equations and balance them. Also, we will learn about the various types of chemical reactions. In the second chapter, we will learn about the various types of acids, bases and salts and their reactions with metals and non-metals. The third chapter will take us to the world of metals and non-metals where we will learn about their properties and reactions among them.
After that image formation by spherical mirrors are discussed. The different types of spherical mirror, convex and concave are taught. The various terms related with spherical mirrors like centre of curvature, radius of curvature etc, focus, pole etc are discussed with ray diagrams. Uses of spherical mirror has been discussed in chapter.
Mirror formula is the way to relate object distance, image distance and focal length of mirror. Magnification is the ratio of size of image by size of object. This is related to ratio of image distance and object distance. Distances are majored from pole of mirror. Sign convention is kept in mind to find relative distances of image and object. Refraction is the phenomena of bending of light when light travels from one medium to another.
The phenomena of refraction can be understood easily by the concepts of refractive index and optical density. This is better explained by an example of rectangular glass slab. This example is dealt. After that concept of Lens is explained.
It is transparent medium bounded by refractive index. Types of Lens —converging and diverging is discussed. Example of converging lens double convex lens and diverging double concave lens. Image formation and terminology is discussed for both convex and concave lens.
Lens formula relates focal length of lens with image distance and object distance. Magnification is related with image and object distance. Sign convention is kept in mind. Power of lens is also discussed.
Numerical based on lens formula and mirror formula are to be solved. Chapter 11 - Human Eye and colorful world Human eye, its components, are discussed. The process of by which human eye can see objects is discussed. The ability of the eye to focus on both near and distant objects, by adjusting its focal length, is called the accommodation of the eye.
The smallest distance, at which the eye can see objects clearly without strain, is called the near point of the eye or the least distance of distinct vision. For a young adult with normal vision, it is about 25 cm. Defects of vision is discussed with their corrective measures using suitable ray diagrams.
The common refractive defects of vision include myopia, hypermetropia and presbyopia. Myopia short-sightedness — the image of distant objects is focussed before the retina is corrected by using a concave lens of suitable power.
Hypermetropia far-sightedness — the image of nearby objects is focussed beyond the retina is corrected by using a convex lens of suitable power. The eye loses its power of accommodation at old age.
The splitting of white light into its component colours is called dispersion. Scattering of light causes the blue colour of sky and the reddening of the Sun at sunrise and sunset. Chapter 12 - Electricity Electricity is required for many thing around us. What is electricity? It is phenomena related to flow of charge. The concept of electric current and electric potential difference voltage is taught. Flow of electrons moving through a conductor constitutes an electric current.
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.
Ohms Law, which establish relationship between potential difference and current is discussed. Concept of resistance and resistivity is studied. Resistance is property of any conductor to resist flow of 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. Resistance of conductor having unit length and cross section is defined specific resistance. Series and parallel combination of resistors are discussed.
In series current is same and in parallel potential difference is same across resistors. The unit of power is watt W. 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. Chapter 13 - Magnetic effects of Current In this chapter relationship between magnetism and electricity is discussed. At first some basics of magnetism is discussed with magnetic field lines.
A compass needle is a small magnet. 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.
Magnetic 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.
The denser magnetic field lines indicate more magnetic field strength. After that, magnetic field due to current carrying conductor is discussed. A metallic wire carrying an electric current has associated with it a magnetic field whose direction is given by right hand thumb rule.
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. Phenomena related to this are explained. This is the basis of an electric motor. An electric motor is a device that converts electric energy into mechanical energy. Working and construction of electric motor is discussed. Electricity generation through magnet is discussed. The phenomenon of electromagnetic induction is the production of induced current in a coil placed in a region where the magnetic field changes with time.
The magnetic field may change due to a relative motion between the coil and a magnet placed near to the coil. If the coil is placed near to a current-carrying conductor, the magnetic field may change either due to a change in the current through the conductor or due to the relative motion between the coil and conductor.
A generator converts mechanical energy into electrical energy. It works on the basis of electromagnetic induction. Two types of generators are discussed. DC generator generates direct current as a cell.
AC generators generates Alternating Current whose direction keep on changing after a time period. Domestic circuiting is discussed. In our houses we receive AC electric power of V with a frequency of 50 Hz. The different aspects is discussed. The concept of live wire, neutral wire and earth wire is discussed.
Earth wire, insulated green which provide, passage for leakage of current. Chapter 14 - Sources of Energy Our energy requirements increase with our standard of living. In order to fulfil our energy requirements, we try to improve the efficiency of energy usage and also try and exploit new sources of energy.
The chapter is all about different sources of energy. Three types of sources of energy are discussed. The first one is conventional sources of energy. These are sources of energy we keep on using from long years. It include fossil fuels, thermal power plant and hydroelectric power plant. These are discussed with advantages and disadvantages. After that, energy sources conventionally used, but improvised due to technology has been discussed. For example, cow dung used initially had low calorific value, and combustion of it causes lot of pollution.
But, with help of technology, it can converted into Bio-gas, which is an efficient and pollution free fuel. Similarly, with the help of technology, wind energy can be harnessed by placing many wind mills in a large field creating a wind farm.
Charcoal obtained from wood is better fuel than wood. All these things are discussed. The third category is Non-conventional sources of energy.
Energy from ocean can be generated through waves, tides or through temperature difference between upper and lower level of ocean. Energy can also be obtained from earth crust, known as geo-thermal energy. Nuclear energy can generated by controlled Nuclear fission reactions. Nuclear fusion reactions generate more energy than fission but are difficult to control.
All such sources of energy are discussed with their advantages and disadvantages. Chapter 15 - Our Environment The various components of an ecosystem are interdependent. The producers make the energy from sunlight available to the rest of the ecosystem. There is a loss of energy as we go from one trophic level to the next, this limits the number of trophic levels in a food-chain.
This concept of food chain and food web is discussed with concept of Biological magnification. It is the process of accumulation of pesticides or other harmful chemicals. Impact of human activities are discussed in this chapter.
The use of chemicals like CFCs has endangered the ozone layer. Since the ozone layer protects against the ultraviolet radiation from the Sun, this could damage the environment.
The different types of waste materials are discussed. Reflection off plane and curved surfaces and bending at the interface of two mediums with different properties. It explains laws for each Reflection and Refraction and briefs into the basic mathematical side of it. There is a total of seventeen questions in this chapter.
