Description:

Strictly Based on Latest NCERT/CBSE Syllabus

Salient features of the book:

• The book has been prepared in accordance with the latest CBSE syllabus and pattern.

• Each Chapter is supported by a large number of Viva Voce Questions (with Answers), Multiple Choice Questions (with Answers).

• Each Section (Physics, Chemistry and Biology) is closed with a set of Projects. The projects are innovative and aimed to stimulate students for scientific research.

• An introduction on How to prepare a Project Report, helps the student to present his/her work in a more

impressive, systematic and scientific way.


Contents:

PHYSICS 

Chapter 1: Electricity and Electric Current • To study the dependence of current (I) on the potential difference (V) across a resistor, determine its resistance, and plot a graph between V andI • To determine the equivalent resistance of two resistors when connected in series • To determine the equivalent resistance of two resistors when connected in parallel

Chapter 2: Reflection and Refraction of Light • To determine the focal length of a concave mirror by obtaining the image of a distant object • To trace the path of a ray of light passing through a rectangular glass slab for different angles of incidence, measure the angle of incidence, angle of refraction, angle of emergence and interpret the results • To determine the focal length of a convex lens by obtaining the image of a distant object • To find the image distance for varying object distances in case of a convex lens and draw the corresponding ray diagrams to show the nature of image formed • To trace the path of the rays of light through a glass prism

Projects

Project P1: Calorific Value of a Fuel

Project P2: Electric Motor

Project P3: Focal Length of a Convex Lens

 

CHEMISTRY

Chapter 1: Chemical Reactions • To study the action of water on quicklime and classify the reaction on the basis of its type • To study the effect of heat on ferrous sulphate crystals and classify the reaction on the basis of its type • To study the behaviour of an iron nail kept in copper sulphate solution and classify the reaction on the basis of its type • To study the reaction between sodium sulphate and barium chloride solutions and classify the reaction on the basis of its type

Chapter 2: Acids, Bases and Salts • To study the properties of an acid (say, dil. hydrochloric acid), by its reactions with (a) Litmus solutions (blue and red) (b) Zinc metal (c) Solid sodium carbonate • To study the properties of an alkali (or base), say dilute solution of sodium hydroxide by its reactions with (a) Litmus solutions (blue and red) (b) Zinc metal (c) Hydrochloric acid • To determine the pH of the following samples by using pH paper or universal indicator: (a) Dilute hydrochloric acid [Dil. HCl(aq)] (b) Dilute solution of sodium hydroxide [Dil. NaOH(aq)] (c) Dilute solution of ethanoic acid [Dil. CH3COOH(aq)] (d) Lemon juice (e) Water (distilled) (f) Dilute solution of sodium hydrogencarbonate [Dil. NaHCO3(aq)]

Chapter 3: Reactivity of Metals • To observe the action of Zinc (Zn), Iron (Fe), Copper (Cu) and Aluminium (Al) metals on the following salt solutions: (a) Zinc sulphate ZnSO4(aq)(b) Ferrous sulphate FeSO4(aq) (c) Copper sulphate CuSO4(aq)(d) Aluminium sulphate Al2(SO4)3(aq)

Based on the above results, arrange Zn, Fe, Cu, and Al metals in decreasing order of reactivity

Chapter 4: Carbon and Its Compounds • To study the following properties of ethanoic acid (or acetic acid), CH3COOH: (a) Odour (b) Solubility in water (c) Effect on litmus (d) Reaction with sodium bicarbonate (or sodium hydrogencarbonate) • To study saponification reaction for the preparation of soap • To study the comparative cleaning capacity of a sample of soap in soft and hard water
