CBSE Class 10 Science Notes: Heredity and Evolution Heredity: The Inheritance of Traits Definition: Heredity is the process by which traits are passed down from parents to their offspring. It’s the reason why children often resemble their parents, inheriting characteristics like eye color, height, and even certain predispositions to diseases. Role of Genes: Genes are […]

CBSE Class 10 Science Notes: How do Organisms Reproduce 🌱 Reproduction: The Essence of Life Definition and Importance: Reproduction is the biological process by which organisms produce new individuals (offspring) of their own kind. It is fundamentally crucial for the continuity of a species, ensuring that life persists from generation to generation. Without reproduction, a

CBSE Class 10 Science Notes: Control and Coordination Tropic Movements in Plants Plant movements are primarily growth-related, influenced by external stimuli. These movements are called tropic movements. Definitions and Examples Phototropism: Growth response of a plant towards light. Example: A plant bending towards sunlight. Geotropism: Growth response of a plant in response to gravity. Example:

CBSE Class 10 Science Notes: Life Processes What Makes Something ‘Living’? – Basic Characteristics Defining life involves identifying key characteristics. Living organisms share a set of fundamental traits that distinguish them from non-living matter. Key Characteristics: Cellular Structure: All living things are composed of cells, the basic units of life. Growth and Development: Living organisms

CBSE Class 10 Science Notes: Carbon and Its Compounds Covalent Bonding and Properties Definition: Covalent bonding involves the sharing of electrons between atoms, primarily non-metals, to achieve a stable electronic configuration (octet rule). Core Principles: Atoms share electrons to attain a full outer shell (like noble gases). Forms molecules with relatively weak intermolecular forces. Basic

CBSE Class 10 Science Notes: Metals and Nonmetals Physical and Chemical Properties: Metals vs. Non-metals This section explores the fundamental differences between metals and non-metals based on their physical and chemical behaviors. Understanding these distinctions is crucial for predicting how these elements will interact with each other and with other substances. Physical Properties Lustre: Metals

CBSE Class 10 Science Notes: Acids Bases and Salts **Definitions by Ion Production** This section explores the fundamental definitions of acids and bases based on their behavior in water. Acids: Substances that produce hydrogen ions ($H^+$) when dissolved in water. These ions are responsible for the acidic properties. Bases: Substances that produce hydroxide ions ($OH^−$)

CBSE Class 10 Science Notes: Chemical Reactions and Equations What is a Chemical Reaction? A chemical reaction is a process that involves the rearrangement of atoms and molecules, leading to the formation of new substances with different properties. It’s a fundamental concept in chemistry, describing how matter changes. Everyday Examples: Rusting of Iron: Iron reacts

CBSE Class 10 Maths Notes: Probability Definitions: Probability Unveiled Probability is a measure of the likelihood that an event will occur. It’s a fundamental concept in mathematics and statistics, helping us quantify uncertainty. Essentially, it tells us “how likely” something is to happen. Probability values range from 0 to 1, where 0 indicates impossibility and
