Welcome to the complete Class 10th Science hub. Here you'll learn every chapter through clear, easy-to-follow notes, then strengthen your understanding with multiple-choice questions, interactive quizzes, printable worksheets and full question banks. Science builds the reasoning and problem-solving skills you'll rely on in higher classes and competitive exams, so getting it right now really matters. With Learnzy Academy you get chapter-wise organisation, instant answer keys and free study tools that make revision faster and exam preparation far less stressful — all in one place, with no sign-up required. Pick a chapter, start practising, and track your progress at your own pace.
Science in Class 10th focuses on building strong fundamentals while introducing more advanced concepts that prepare you for senior classes and competitive exams. Across its chapters you'll move from core definitions and rules to applying them in problems, experiments and real situations — the kind of understanding that lasts well beyond a single exam.
Studying Science sharpens skills you'll use everywhere: logical reasoning, careful analysis, attention to detail and structured problem-solving. These skills appear in everyday decision-making and in almost every career path, which is why a solid foundation now pays off for years.
Key learning outcomes: understand each chapter's core ideas, connect topics to real-world applications, solve a wide range of questions confidently, and revise efficiently so you can perform your best when it matters most. This page is built to guide you from your first chapter all the way to a full mock test.
Open a chapter below to read its notes, attempt the MCQs and quiz, then download a worksheet. Use the Study Tools to generate extra practice and finish with a mock test before your exam.
Every chapter with its own notes, MCQs, quiz, worksheet and question bank — open any card to start.
Introduction A chemical reaction is a process in which one or more substances (called reactants) change to form new substances (called products). These changes may involv
What are Acids? Acids are substances that taste sour and can turn blue litmus paper red. They produce hydrogen ions (H⁺) when dissolved in water. Examples: Lemon juice (c
Metals: Metals are elements that are usually hard, shiny, and strong. They are good conductors of heat and electricity. Most metals are solid at room temperature (except
Carbon is a non-metallic element found in all living things. It is a very important element because it can form a large number of compounds — more than any other element.
Life processes are the essential activities that all living organisms perform to stay alive. These processes help organisms to grow, get energy, remove waste, and reprodu

Heredity is the process by which traits or characteristics are passed from parents to their offspring. It is the reason why offspring resemble their parents and inherit s
Light is a form of energy that travels in the form of waves. It behaves in two main ways when it interacts with surfaces: reflection and refraction. Reflection of Light:
The human eye is an organ that detects light and allows us to see. It works like a camera by focusing light onto the retina, which sends signals to the brain to form an i

When an electric current flows through a conductor (like a wire), it produces a magnetic field around it. This is called the magnetic effect of electric current. Key Conc

Generate TestHow to study Science effectively: always begin with the notes to understand a concept, not just memorise it. Once a chapter makes sense, attempt its MCQs and a quiz immediately — active recall locks learning in far better than re-reading. Keep a running list of formulas, definitions or rules you tend to forget and review it often.
Chapter prioritisation: start with foundational chapters that other topics depend on, then give extra time to high-weightage chapters (see "Most Important Chapters" below). Don't leave easy chapters for the last day — secure those marks early.
Weekly study plan: aim for 1–2 chapters a week. Spend the first half of the week learning and practising, and the second half on worksheets and a short test to check retention.
Revision strategy: revise in short, spaced sessions rather than one long cram. Use quizzes to spot weak chapters, revisit only those, and re-attempt the questions you got wrong a day or two later.
Mistakes to avoid: skipping notes and jumping straight to questions, ignoring worksheets, and never taking a timed test. Also avoid passive reading — if you can't explain a topic in your own words, you haven't learnt it yet.
Time management: set a fixed daily study slot, take short breaks to stay fresh, and always solve at least one full-length mock test under timed conditions before the exam so the real paper feels familiar.
