NCERT Class 9 Science

By learning the important points to remember, students will be able to prepare notes that will be helpful for students later on. CBSE Class 9 Science deals with various concepts from the different divisions of Science – Chemistry, Physics and Biology. In the sections below, we have provided some important points that students must learn from each chapter.

• Matter:
  • Anything which has mass and occupies some space is called matter.
  • Solid, liquid and gas are not substances but three different states of the same substance.
• Laws of Chemical Combination :
  • The combination between the elements is governed by the laws of chemical combination.
  • The law of conservation of mass was given by Lavoisier.
  • The law of constant proportions was given by Louis Proust.
  • The law of constant proportions is applicable only to pure chemical compounds.

• Cell Theory:
  • The cell theory was proposed by Schleiden and Schwann, which states, “All the plants and animals are composed of cells, and the cell is the basic unit of life”.
  • Rudolf Virchow further expanded the cell theory by suggesting that all cells arise from pre-existing cells.
• Classification and Evolution:
  • The variation among living organisms with respect to their external and internal structures, genetic characteristics, feeding habits, habitats and behaviour is called biodiversity.
  • Charles Darwin first described the idea of evolution in 1859 in his book, The Origin of Species.

• Force:
  • Force generally denotes push or pull.
  • Force can (a) produce motion, (b) stop motion, (c) change the direction of motion, and (d) change the dimension of a body.
  • Force is defined as an external agent which changes or tends to change the state of rest or uniform motion of a body or changes the direction of the body or deforms the body.
• Mass and Weight:
  • Mass is the amount of matter contained in a body. It is a scalar quantity, and its SI unit is the kilogram (kg).
  • Weight is the pull exerted on a body by the Earth. It is defined as the product of mass (m) and acceleration due to gravity (g). It is a vector quantity, and its SI unit is the newton.
  • The mass of an object is constant and does not change from place to place whereas its weight depends on its location because g depends on location.

NCERT Class 9 Maths

Maths is one of the most fun-to-learn and easiest subjects if you practice questions thoroughly. Students must ensure that they follow the important points from each chapter. This will make it easier for them to remember the concepts that will help them in their exam preparation. In the sections below, we have provided some important points to remember for CBSE Class 9 Maths:

• Number Systems
  • Natural Numbers: These are the counting numbers (1, 2, 3, etc.).
  • Whole Numbers: The set of numbers that includes all natural numbers and the number zero are called whole numbers. Whole numbers are also called Non-negative integers.
  • Prime Numbers: A natural number larger than 1 is a prime number if it does not have other divisors except for itself and 1. (The lowest prime number is 2. 2 is also the only even prime number. The lowest odd prime number is 3.)
• Standard Form of Linear Equation in Two Variables:
  • An equation of the form ax + by + c = 0, where a, b, and c are real numbers such that a and b are not zero, is called a linear equation in two variables.
• A linear equation in two variables has infinitely many solutions.
• Axioms and Theorems:
  • There are three basic terms in geometry, namely “Point”, “Line” and “Plane”. It is not possible to define these three terms precisely. So, these are taken as undefined terms.
  • Axioms or postulates are the basic facts which are taken for granted without proof.
  • Theorems are statements which are proved through logical reasoning based on previously proven results and some axioms.
