13 of 13 ChaptersNutrition in Plants
Autotrophic vs heterotrophic nutrition, photosynthesis equation, stomata, chlorophyll, insectivorous plants (pitcher plant), saprotrophs (fungi), and nitrogen replenishment.
Nutrition in Animals
Different ways of taking food, human digestive system (mouth, oesophagus, stomach, small intestine, large intestine), digestion in grass-eating ruminants, and feeding in amoeba.
Heat
Hot and cold, clinical and laboratory thermometers, temperature measurement, conduction in solids, convection in liquids/gases (sea breeze & land breeze), and radiation.
Acids, Bases and Salts
Natural indicators (litmus, turmeric, China rose), properties of acids (sour) and bases (bitter), neutralisation reaction in laboratory and daily life (indigestion, ant sting).
Physical and Chemical Changes
Physical changes (reversible, no new substance), chemical changes (new substance formed, energy change), rusting of iron, galvanisation, and crystallisation of copper sulphate.
Respiration in Organisms
Aerobic vs anaerobic respiration, breathing rate, human respiratory system (inhalation, exhalation, diaphragm), breathing in other animals (cockroach, earthworm, fish), and plant respiration.
Transportation in Animals & Plants
Circulatory system: blood (RBC, WBC, platelets), blood vessels (arteries, veins, capillaries), heart structure and heartbeat. Excretory system in humans, and xylem/phloem transport in plants.
Reproduction in Plants
Modes of reproduction: asexual (vegetative propagation, budding, fragmentation, spore formation) and sexual (flower parts, pollination - self and cross, fertilisation, seed dispersal).
Motion and Time
Slow or fast motion, speed formula (Distance/Time), measurement of time using simple pendulum (time period), uniform vs non-uniform motion, and distance-time graphs.
Electric Current & Its Effects
Symbols of electric components, heating effect of electric current (heating elements, electric fuse, MCB), magnetic effect of current, electromagnet, and electric bell mechanism.
Light
Rectilinear propagation of light, reflection by plane mirror (virtual, erect, lateral inversion), spherical mirrors (concave and convex), spherical lenses, and dispersion of white light into spectrum (Newton’s disc).
Forests: Our Lifeline
Forest structure: canopy, understorey, forest floor. Food chains, decomposers and humus, water cycle regulation, prevention of soil erosion, and forest conservation.
Wastewater Story
Sewage generation, contaminants, sewerage system, Wastewater Treatment Plant (WWTP) processes (bar screens, grit chamber, clarifier, aeration), and better housekeeping practices.
