Class-10 Science Syllabus 2023-24

Science Syllabus Class10 2023-24

The unveiling of the CBSE Class 10 Science Syllabus for the academic session of 2023-24 ushers in a profound reflection on two pivotal dimensions: perplexity and burstiness. Within the intricate tapestry of syllabus intricacies, students navigate the labyrinthine realm of scientific knowledge. The ebb and flow of complexity, intertwined with diversity, sculpt their academic voyage. In the context of human instruction, these attributes resonate through the alternating cadence of succinct and elaborate narratives.

The document encapsulating the intellectual odyssey, the “CBSE Class 10 Science Syllabus 2023-2024,” stands as a testament to this synergy of complexity and diversity. Five overarching themes delineate the landscape of scientific exploration: Materials, The World of The Living, How Things Function, Natural Phenomena, and Natural Resources. Akin to the chiseling of fine marble, the curriculum underwent a 30% reduction in the previous academic year, a phenomenon that persists in the current session. The annulled fragments of the syllabus, now relegated to obscurity, shall no longer cast their shadows upon the evaluation for AY 2023-24. The aperture to explore these deletions remains accessible through the provided link, alongside the comprehensive CBSE Class 10 Science Syllabus.

Specific directives and decrees govern the pedagogical vessel on which students sail:

A comprehensive Annual Examination, enshrining the entire syllabus, awaits them.

An 80-mark Annual Examination, adorned with the vestiges of scholarship, retains 20 marks earmarked for Internal Assessment.

The realm of Internal Assessment unfurls with the following facets: a. Periodic Assessment, an intricate mosaic comprising three cycles of intellectual scrutiny. From this multifaceted spectrum, the top two performances shall bear the weight of 05 marks in the grand assessment. b. Practical and laboratory endeavors, a persistent endeavor throughout the academic voyage. These endeavors shall remain etched in the annals of continuous evaluation, contributing 5 marks to the final verdict. Each practical endeavor mandated by the syllabus must find its completion. c. Portfolio construction, the tapestry woven from the student’s classwork and diverse specimens of their creative endeavors. This compilation weaves a tapestry that shall bear a weightage of 5 marks in the ultimate adjudication.

The CBSE Class 10 Science Syllabus for 2023-24 carries its unique resonance. The salient elements bear the following insignia:

Total 80 Internal assessment 20 Grand Total 100

The saga of exploration within the precincts of this syllabus commences with the theme of “Materials.”

Unit 1: Chemical Substances – Nature and Behavior Chemical reactions are the epicenters of inquiry, encompassing chemical equations and their equilibrium. The repertoire of chemical reactions extends through combination, decomposition, displacement, double displacement, precipitation, and endothermic and exothermic reactions. Oxidation and reduction constitute the philosophical underpinning.

The alchemy of acids, bases, and salts finds its enigma in the notion of hydrogen and hydroxide ions, and their utility in neutralization. The concept of the pH scale, though its logarithmic intricacies are cast into obscurity, retains its significance. Sodium Hydroxide, Bleaching powder, Baking soda, Washing soda, and Plaster of Paris are the constituent materials that grace this thematic overture.

Metals and non-metals stand in stark contrast, and their properties unfurl as a dramatic diorama. The reactivity series, the birth of ionic compounds, and the variegated hues of corrosion and its containment weave a narrative of scientific intrigue.

Carbon compounds, the versatile progeny of carbon, find their elucidation. Covalent bonding, homologous series, and nomenclature take center stage. The symphony of carbon compounds resonates with the presence of halogens, alcohols, ketones, aldehydes, alkanes, and alkynes. The tales of combustion, oxidation, addition, and substitution reactions offer a glimpse into their chemical idiosyncrasies.

The theme “The World of the Living” beckons with life processes, their nurturing and sustenance, respiration, transport, and excretion in the botanical and zoological realms. The kaleidoscope of control and coordination spans tropic movements in plants, the orchestra of plant hormones, and the intricate choreography of the nervous system. The concert of voluntary, involuntary, and reflex actions finds resonance. Chemical orchestration through animal hormones casts its shadow on this symphony.

Reproduction unfurls its tapestry in both asexual and sexual renditions. The narrative transcends into the precincts of reproductive health, embracing the facets of family planning, the dialectic between safe sex and HIV/AIDS, and the chronicles of childbearing and women’s health.

Heredity and Evolution, the final thematic overture, follows the intricate trails of inheritance, courtesy of Mendel’s seminal contributions. The laws governing the inheritance of traits, the enigma of sex determination, and the intricacies of evolution form the central theme.

The symphony of “Natural Phenomena” commences with the reflection of light by curved surfaces, revealing images formed by spherical mirrors and the accompanying theoretical underpinnings.

Refraction, the phenomenon of light’s bending, marches in tandem with its laws and refractive indices. The tapestry unfurls with the inclusion of spherical lenses, their image formations, and the calculation of lens powers.

The human eye, that remarkable optical instrument, receives its moment in the spotlight. Functionality, defects, and their redressal stand at the forefront. Spherical mirrors and lenses find their applications.

The enigma of light’s refraction through prisms, the dispersion and scattering of light, and their quotidian applications beckon.

The theme “How Things Work” delves into the realm of electricity and magnetism. Electric current, potential difference, and Ohm’s law find their articulation. The dialectic of resistance, resistivity, and their dependency stand in bold relief. The orchestration of resistors in series and parallel configuration unveils their everyday implications.

The heating effect of electric current, along with its quotidian applications, finds its niche. The relationship between power, voltage, current, and resistance is meticulously explored.

Magnetic effects of current come into play, marked by magnetic fields, the lines of force, and the realms created by current-carrying conductors and coils. The intriguing interplay of forces, as guided by Fleming’s Left Hand Rule, manifests in direct and alternating currents.

The theme “Natural Resources” frames the discourse on the environment, ecosystem dynamics, environmental
