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 • Studying the dependence of potential difference (V) across a resistor on the current (I) passing through it and determine its resistance. Also plotting a graph between and I • Determination of the equivalent resistance of two resistors when connected in series and parallel

Chapter 2: Reflection and Refraction of Light • Determination of the focal length of (a) Concave mirror (b) Convex mirror by obtaining the image of a distant object • Tracing 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 • Finding the image distance for varying object distances in case of a convex lens and drawing corresponding ray diagrams to show the nature of image formed • Tracing 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 • Performing and observing the following reactions and classifying them into: (a) Combination reaction (b) Decomposition reaction (c) Displacement reaction (d) Double displacement reaction (i) Action of water on quick lime (ii) Action of heat on ferrous sulphate crystals (iii) Iron nails kept in copper sulphate solution (iv) Reaction between sodium sulphate and barium chloride solutions

Chapter 2: Acids, Bases and Salts • Studying the properties of acids and bases (HCl & NaOH) by their reaction with: (a) Litmus solution (blue/red) (b) Zinc metal (c) Solid sodium carbonate • Finding the pH of the following samples by using pH paper or universal indicator: (a) Dilute hydrochloric acid [Dil. HCl(aq)] (b) Dilute NaOH solution [Dil. NaOH(aq)] (c) Dilute ethanoic acid solution [Dil. CH3COOH(aq)] (d) Lemon juice (e) Water (distilled) (f) Dilute hydrogencarbonate solution [Dil. NaHCO3(aq)]

Chapter 3: Reactivity of Metals • Observing the action of Zn, Fe, Cu and Al metals on the following salt solutions: (a) ZnSO4(aq) (b) FeSO4(aq) (c) CuSO4(aq) (d) Al2(SO4)3(aq)

Arranging Zn, Fe, Cu and Al (metals) in the decreasing order of reactivity based on the above result

Chapter 4: Carbon and Its Compounds • Study of the following properties of acetic acid (ethanoic acid): (i) odour (ii) solubility in water (iii) effect on litmus (iv) reaction with sodium hydrogencarbonate • Study of the comparative cleaning capacity of a sample of soap in soft and hard water
