Summary
Highlights
Focus on soaps and micelles, including diagrams and explanations. Understand why soap doesn't work in hard water. Review reactions of ethanol and ethanoic acid, esterification, homologous series, covalent bonds, and hydrocarbons. For Acids, Bases & Salts, concentrate on salt preparation, properties, equations, especially baking soda, POP, and bleaching powder. Know why acid should be added to water slowly. In Metals & Non-metals, study copper refining, anode mud, and reactions with water (cold, hot, steam). Understand calcination, roasting, and general metal/non-metal properties. Review chemical indicators, decomposition, displacement reactions, reactivity series, and the color changes in various chemical reactions and precipitates (e.g., lead nitrate).
Master ray diagrams for lenses and mirrors (convex, concave). Understand refractive index and practice related numericals. Memorize mirror formula (1/f = 1/v + 1/u) and magnification formula. Know the SI unit of power (diopter). Learn about eye defects like myopia and hypermetropia, their causes, cures, and effects on the retina and eyeballs. Understand rainbow formation, total internal reflection, and the scattering of light. For Magnetic Effects, study magnetic effects around a straight current-carrying conductor and solenoids. Know Fleming's Left-Hand Rule and the Thumb Rule. In Electricity, differentiate between parallel and series resistance, identify which is used at home, calculate total current and potential difference, and understand VI graphs and Ohm's Law.
Focus on the functions of digestive enzymes (trypsin, lipase, HCL). Study nephron and kidney structure and function, including diagrams and concepts like Bowman's capsule and reabsorption. Understand the difference between lung and kidney filtration. Know about the aorta and double vs. single circulation. Study stomatal functions. For Heredity, master monohybrid and dihybrid crosses, F1/F2 generations, phenotypic/genotypic ratios, and the green round seed and yellow wrinkled seed problem. Understand why chromosome numbers remain constant across generations and learn about meiosis, mitosis, and mutation. In Our Environment, study ozone layer formation, depletion by CFCs, and prevention. Understand plastic pollution and biomagnification, along with the 10% law. In Control & Coordination, focus on reflex actions, stimulus, brain parts and their functions (cerebrum, cerebellum, hindbrain, medulla), and plant hormones. In How Do Organisms Reproduce, study binary and multiple fission, budding, regeneration, sexual reproduction (male/female reproductive parts), fertilization (in flowers and human body), placenta functions, and sexually transmitted diseases like AIDS.
