Heat
Heat as a form of energy and its units, joule(J) and calorie (cal) Temperature Different units of Temperature (°C, °F, K) Conversion from one scale to another Measuring temperature The laboratory thermometer The clinical thermometer Effects of Heat Change in temperature Change in size (Expansion and contraction) Change in state Good conductors and bad conductors of heat and their examples Choice of conductors and insulators in day to day life (Pan handles, metal cooking utensils etc.) Methods of Heat Transfer Conduction Convection Radiation Thermos Flask: (Application of heat transfer)
Acid, Bases and Salts
Acids- types, properties and uses Bases- types, properties and uses Salts- preparation, properties and uses Testing for acids and bases
Physical and Chemical Changes
Chemical change - formation of a new product with new properties Differentiating between physical and chemical change Classification as physical & chemical change Characteristics of chemical reactions Evolution of a gas Change of colour Formation of precipitate Change in energy Change of state Types of chemical reactions Combination reaction Decomposition reaction Single displacement reaction Double displacement reaction Oxidation and reduction reactions Separating a solid from a solution By evaporation Crystallisation
Weather, Climate and Adaptations of Animals to Climate
Weather Elements of weather Predicting the weather Climate Effect of the sun on climate Climate and adaptation Adaptation of animals Adaptations to cold climates Adaptation to hot climates-deserts Adaptation to hot and wet climates-tropical rainforests
Winds, Storms and Cyclones
Air pressure Power of air pressure Air exerts pressure in all directions High speed wind causes reduced pressure Air expands on heating Wind currents Wind currents due to uneven heating between equator and poles Wind currents due to uneven heating of land and water Thunderstorms, cyclones and tornadoes Cyclone forecasting and warning
Natural Resources and Their Conservation
Our natural resources Renewable and non-renewable resources Water - a renewable resource Shortage of water States of water Water cycle Groundwater Water conservation Forest wealth Prevent floods and maintain the water table Prevent soil erosion Supply oxygen Absorb carbon dioxide Cool the air and increase rainfall Provide food and shelter for wildlife Forests products Plants also depend on animals Producers, consumers and decomposers Food chain Balance in nature Forest conservation Wastewater and sewage Importance of drainage and sanitation The sewage system Sewage treatment Wastewater treatment plant Better housekeeping practices Alternate methods for sewage disposal
Respiration in Organism
Respiration in plants Root respiration Respiration in animals Through cell membrane or skin Through air holes Through gills Through lungs The respiratory system in humans Breathing in To the lungs In the lungs How air enters the lungs Cellular respiration Types of respiration Aerobic respiration Anaerobic respiration Difference between combustion and cellular respiration Difference between breathing and cellular respiration
Transportation in Plants and Animals
Transportation of materials in plants: Vascular system, xylem, phloem, osmosis Transportation of water and minerals Transportation of food Transportation of materials in animals Transportation in humans Heartbeat and pulse Excretion Excretion in animals Excretion in humans Sweating
Reproduction in Plants
Asexual reproduction in plants Fragmentation Budding Spore formation Vegetative reproduction in plants Artificial methods of vegetative reproduction Grafting Cutting Layering Tissue culture Advantages of vegetative reproduction Sexual reproduction Sexual reproduction in plants Pollination Fertilization Seed formation Fruit formation Dispersal of seeds Germination of seeds
Motion and Time
Measurement Measurement of time Simple pendulum Sand clock and sundial Motion as a change in position of an object with respect to time Types of motion Translatory Circulatory Oscillatory Repetitive (Periodic and Non-Periodic) Random Uniform and non-uniform motion Weight Concept Differences between mass and weight Speed Distance-time graph for uniform motion
Electric Current and its Effect
Electric current and electric circuits Components of an electric current Circuit diagram Electric current as a flow of charges Electric cell as source of electricity Resistors as components that oppose the flow of current Simple electric circuit - Series and Parallel Battery as a collection of cells connected in series Good and Bad conductors of electricity Potential difference Effects of electric current Heating and lighting effect The electric fuse is based on the heating effect of current Magnetic effect Solenoid The electromagnet Uses of electromagnet Test for a magnet (by repulsion)
Light
Rectilinear propagation of light Reflection of light: Definition and examples Terms related to reflection - Normal, plane, point of incidence, angle of incidence, angle of reflection Laws of Reflection Real and virtual images Plane mirror Uses Ray Diagram (no mention of virtual image) Characteristics of the image formed (Lateral Inversion, same size, distance is preserved) Spherical mirrors: Concave mirror, Convex mirror Principal focus Image formed by a spherical mirror Uses of spherical mirror Differences between images formed by plane, concave and convex mirror Speed of light (3 X 108 m/s) Primary colours (RGB) Formation of secondary colours by colour addition Appearance of colour of an object (Based on reflection and absorption) Colour subtraction Lenses Terms related to lenses Principal focus and focal length Image formed by a lens The spectrum Rainbow Prism
