CBSE Class 11 Science Curriculum (PCM Stream)

The Class 11 PCM (Physics, Chemistry, Mathematics) curriculum is designed to deepen students' understanding of scientific and mathematical principles, laying a strong foundation for engineering and related fields.

Core Subjects:

  • 1. Physics
    • Exploring the physical world, units of measurement, and vector analysis.
    • Studying kinematics, laws of motion, work, energy, power, and gravitation.
    • Understanding properties of bulk matter, thermodynamics, and oscillations.
  • 2. Chemistry
    • Delving into basic concepts, atomic structure, and periodic classification.
    • Examining chemical bonding, thermodynamics, equilibrium, and redox reactions.
    • Introducing organic chemistry and hydrocarbons.
  • 3. Mathematics
    • Studying sets, relations, functions, and trigonometry.
    • Exploring complex numbers, quadratic equations, and linear inequalities.
    • Understanding sequences, series, and coordinate geometry.

Study Recommendations:

  • Conceptual Mastery: Focus on understanding and internalizing core principles.
  • Regular Problem-Solving: Engage in daily practice to enhance analytical and problem-solving skills.
  • Time Management: Develop effective strategies to balance the rigorous demands of each subject.
  • Seek Guidance: Utilize mentor support and peer discussions to clarify doubts and reinforce learning.

Class 11 PCM curriculum is rigorous and demands a deep commitment to learning. Mastery of these subjects is crucial for success in competitive exams like JEE and for future endeavors in engineering and technology.

Physics (Grade 11)

  • 1. Kinematics - Motion in a Straight Line
    • Galileo’s Thought Experiment
      Galileo imagined dropping two objects of different masses from the Leaning Tower of Pisa. Contrary to Aristotle’s belief, he found that they fell at the same rate, proving that acceleration due to gravity is independent of mass (in the absence of air resistance).
  • 2. Work, Energy, and Power
    • Example of Work Done = Zero
      When a person carries a heavy suitcase horizontally, no work is done against gravity (since displacement is perpendicular to force). However, energy is spent in holding the suitcase, due to internal muscular forces.
  • 3. Gravitation
    • Why Astronauts Float in Space?
      They are not in zero gravity, but in free fall around Earth. Since both the astronaut and the spacecraft fall at the same rate, it creates an illusion of weightlessness.

Chemistry (Grade 11)

  • 1. Atomic Structure
    • Quantum Model of Hydrogen Atom (Bohr vs. Schrodinger)
      • Bohr’s Model: Electrons move in fixed orbits.
      • Schrodinger’s Model: Electrons exist in probability clouds (orbitals), not fixed paths.
  • 2. States of Matter
    • Why do LPG Cylinders Feel Cold?
      When gas expands, it absorbs heat from its surroundings (Joule-Thomson effect), making the cylinder feel cold.
  • 3. Chemical Bonding
    • Why is Diamond Hard, but Graphite Soft?
      • Diamond: Carbon atoms bonded in a tetrahedral lattice → Very strong.
      • Graphite: Carbon arranged in layers with weak forces → Soft and slippery.

Biology (Grade 11)

  • 1. Cell Structure and Function
    • How Do Cells "Talk" to Each Other?
      Cells communicate via chemical signals (hormones, neurotransmitters). Example: Insulin signals cells to absorb glucose.
  • 2. Transport in Plants
    • Why Can’t You Water a Plant with Saltwater?
      Saltwater creates hypertonic conditions, drawing water out of cells → Causes wilting.
  • 3. Human Physiology - Digestive System
    • Why Do You Feel Sleepy After Eating?
      Digesting food requires energy → Blood flow increases in the digestive system, reducing oxygen to the brain → Feeling drowsy.

CBSE Class 12 Science Curriculum (PCB Stream)

Physics (Grade 12)

  • 1. Electrostatics
    • Why Does a Balloon Stick to a Wall After Rubbing?
      Rubbing transfers negative charge to the balloon → Induces positive charge on the wall → Attraction occurs.
  • 2. Dual Nature of Matter
    • Are Electrons Particles or Waves?
      • In photoelectric effect, electrons behave as particles.
      • In electron diffraction, they behave as waves. → Shows wave-particle duality.
  • 3. Nuclear Physics
    • How Do Nuclear Power Plants Work?
      • Controlled fission of Uranium-235 releases energy → Heats water → Produces steam → Drives turbines for electricity.

Chemistry (Grade 12)

  • 1. Electrochemistry
    • Why Do Lemon Batteries Work?
      Lemon juice acts as an electrolyte, allowing electrons to flow between zinc and copper electrodes → Generates a small voltage.
  • 2. Chemical Kinetics
    • Why Does Food Spoil Faster in Summer? Higher temperature → Increases reaction rate of microbial activity → Faster decomposition.
  • 3. Polymers
    • Why is Teflon (Non-Stick Coating) So Slippery?
      • Its fluorine atoms create a surface that repels almost all substances, making it non-stick.

Biology (Grade 12)

  • 1. Human Reproduction
    • Why are Testes Located Outside the Body?
      Sperm production requires a temperature lower than body temperature → Testes remain in the scrotum for cooling.
  • 2. Genetics - DNA & RNA
    • How Do Scientists Edit Genes?
      Using CRISPR-Cas9, scientists can cut and modify specific DNA sequences, revolutionizing medicine.
  • 3. Ecology - Global Warming
    • How Can Trees Reduce Global Warming?
      Trees absorb CO₂ through photosynthesis, reducing the greenhouse effect and slowing climate change.
