Focus on the phenomenon of evaporation and the cooling it causes. |
| Ch 2: Is Matter Around Us Pure? | Mixtures, Solutions, Separating Components. | Differentiates between pure substances (elements and compounds) and mixtures (homogeneous and heterogeneous). Introduces concepts like concentration, suspension, and colloid, along with various separation techniques (e.g., distillation, chromatography). |
| Ch 3: Atoms and Molecules | Laws of Chemical Combination, Atomic and Molecular Mass, Mole Concept. | Establishes the foundational Laws of Chemical Combination (Conservation of Mass and Constant Proportions). Defines atoms and molecules and teaches how to write chemical formulae. The Mole Concept and Avogadro’s number are introduced. |
| Ch 4: Structure of the Atom | Sub-atomic Particles, Atomic Models, Isotopes, Isobars. | Explores the existence and properties of electrons, protons, and neutrons. Details historical atomic models (Thomson’s, Rutherford’s, Bohr’s), and explains concepts like valency, atomic number, and mass number. |
🔬 Biology (Organization in the Living World & Food Production)
| Chapter | Main Topics Covered | Summary of Core Concepts |
| Ch 5: The Fundamental Unit of Life | Cell, Cell Organelles, Cell Division. | The cell is introduced as the basic structural and functional unit of life. Detailed study of the structure of the cell, including the cell membrane, nucleus, cytoplasm, and cell organelles (Mitochondria, Endoplasmic Reticulum, etc.). |
| Ch 6: Tissues | Plant Tissues, Animal Tissues. | Explains that tissues are groups of cells with a common function. Covers the types and functions of plant tissues (meristematic and permanent) and animal tissues (epithelial, muscular, connective, and nervous). |
| Ch 12: Improvement in Food Resources | Crop Management, Animal Husbandry. | Focuses on sustainable ways to enhance food production. Discusses crop variety improvement, crop protection, and management of farming systems like cattle farming, poultry farming, and pisciculture (fishery). |
⚙️ Physics (Motion, Force and Work)
| Chapter | Main Topics Covered | Summary of Core Concepts |
| Ch 7: Motion | Displacement, Velocity, Acceleration, Graphical Representation. | Introduces the language of motion, distinguishing between distance and displacement, and speed and velocity. Covers acceleration and the graphical representation of motion, culminating in the three equations of motion. |
| Ch 8: Force and Laws of Motion | Newton’s Laws, Inertia, Momentum, Conservation of Momentum. | Defines force and introduces Newton’s three Laws of Motion. Explores the concepts of inertia (the tendency to resist change in state of motion) and momentum, along with the crucial Law of Conservation of Momentum. |
| Ch 9: Gravitation | Universal Law, Free Fall, Mass & Weight, Thrust & Pressure. | Presents the Universal Law of Gravitation and its significance. Discusses the acceleration due to gravity (g), the difference between mass and weight, and the concepts of Thrust and Pressure. |
| Ch 10: Work and Energy | Work, Kinetic and Potential Energy, Law of Conservation of Energy. | Provides the scientific definition of work done by a constant force. Defines energy and its two main forms: Kinetic Energy and Potential Energy. Concludes with the powerful Law of Conservation of Energy. |
| Ch 11: Sound | Production, Propagation, Characteristics, Reflection. | Explains the production and propagation of sound (as a wave). Discusses the characteristics of sound waves (pitch, loudness, quality) and phenomena like the reflection of sound (echo and reverberation). |
1. Annual Theory Examination (80 Marks)
The final examination is a 3-hour paper covering the entire syllabus and is structured to test different types of knowledge and skills.
