Welcome to Teachoo’s complete learning resource for Class 7 Science. Students can study the new NCERT Science textbook Curiosity, as well as chapters from the old NCERT Class 7 Science book.

Class 7 Science develops the foundation introduced in Class 6. Students move from basic observations to deeper scientific explanations involving acids and bases, electricity, metals and non-metals, physical and chemical changes, adolescence, heat transfer, motion, life processes, light and astronomy.

Teachoo helps students understand these topics through chapter-wise notes, NCERT solutions, important questions, MCQs, assertion-reason questions, case-based questions, exploratory projects and video lessons. Explanations are written in simple language but include the correct scientific terms required in school examinations.

Whether your school follows the new NCERT Class 7 Science Curiosity textbook or still uses chapters from the previous NCERT book, you can find the relevant concepts and solutions here.

NCERT Class 7 Science Curiosity

The new Curiosity Class 7 Science book encourages students to learn Science through observation, investigation, experimentation and discussion. Instead of treating Physics, Chemistry and Biology as completely separate subjects, the book connects scientific ideas with events students observe in daily life.

The 12 chapters of NCERT Class 7 Science Curiosity are:

1. The Ever-Evolving World of Science

This introductory chapter explains that scientific knowledge continues to develop as people make new observations, conduct experiments and discover better explanations. Students learn to ask scientific questions and examine evidence instead of accepting ideas without investigation.

2. Exploring Substances: Acidic, Basic and Neutral

Students learn how substances can be classified as acidic, basic or neutral. The chapter introduces natural indicators, colour changes, neutralisation and familiar examples of acids and bases found at home and in the environment.

3. Electricity: Circuits and Their Components

This chapter introduces electric cells, bulbs, switches, connecting wires and electric circuits. Students learn the conditions required for a bulb to glow, the difference between open and closed circuits, and how circuit components work together.

4. The World of Metals and Non-metals

Students investigate the physical properties of metals and non-metals. They compare materials based on properties such as lustre, hardness, conductivity and response to different conditions, while also learning about their everyday uses.

5. Changes Around Us: Physical and Chemical

This chapter explains the difference between physical and chemical changes. Students examine situations in which only the appearance or state of a substance changes and situations in which an entirely new substance is formed.

6. Adolescence: A Stage of Growth and Change

Students learn about adolescence as the transition from childhood to adulthood. The chapter discusses physical and emotional changes, growth, personal hygiene, nutrition and the importance of developing healthy habits during adolescence.

7. Heat Transfer in Nature

This chapter explains how heat travels from a hotter object or region to a colder one. Students study conduction, convection and radiation and connect these processes with natural events and everyday experiences.

8. Measurement of Time and Motion

Students explore how time and motion are measured. The chapter develops an understanding of speed and the relationship between distance, time and motion through observations, measurements and numerical examples.

9. Life Processes in Animals

This chapter examines the processes that keep animals alive. Students learn how animals obtain and digest food, respire, transport materials within the body and remove wastes.

10. Life Processes in Plants

Students explore how plants obtain nutrition, exchange gases, transport water and food, and carry out other essential life processes. The chapter connects the different parts of a plant with the functions they perform.

11. Light: Shadows and Reflections

This chapter explains how light travels, how shadows are formed and how light is reflected. Students investigate the conditions required for shadow formation and observe reflection through familiar objects and activities.

12. Earth, Moon and the Sun

Students study the relationship between Earth, the Moon and the Sun. The chapter uses observations of the sky to introduce astronomical patterns and explain how the movements of celestial objects affect what we see from Earth.

Together, these chapters create a connected journey through Chemistry, Physics, Biology, health science and astronomy. Each chapter builds scientific thinking by asking students to observe, predict, test and explain.

Old NCERT Class 7 Science Chapters

Teachoo also includes learning resources for the previous NCERT Class 7 Science textbook. These chapters remain useful for schools referring to the older syllabus, teachers searching for additional questions and students who want extra practice.

The old NCERT Class 7 Science book contains 18 chapters:

Nutrition in Plants
Nutrition in Animals
Fibre to Fabric
Heat
Acids, Bases and Salts
Physical and Chemical Changes
Weather, Climate and Adaptations of Animals to Climate
Winds, Storms and Cyclones
Soil
Respiration in Organisms
Transportation in Animals and Plants
Reproduction in Plants
Motion and Time
Electric Current and Its Effects
Light
Water: A Precious Resource
Forests: Our Lifeline
Wastewater Story

These chapters cover several essential scientific ideas. Biology topics include plant nutrition, animal digestion, respiration, circulation, excretion and reproduction. Physics topics include heat, motion, electric current, electric circuits and light. Chemistry topics include acids, bases, salts, indicators, neutralisation and physical and chemical changes.

The old book also contains important environmental topics such as weather, climate, soil, water conservation, forest ecosystems, sewage treatment and wastewater management.

Keeping the new Curiosity chapters and old NCERT chapters together helps students find a topic even when its chapter name, number or organisation has changed.

What Will Students Find on Teachoo?

Teachoo organises Class 7 Science into manageable concepts and question sets. Depending on the chapter, students can study:

Easy and detailed chapter notes
Important definitions and scientific terms
Activities and experiments explained step by step
NCERT questions with complete solutions
Questions given at the end of the chapter
Teachoo’s additional practice questions
Multiple-choice questions
Assertion-reason questions
Case-based and competency-based questions
Exploratory projects
Important diagrams and examples
Revision material and video explanations

The solutions do more than state the final answer. Important steps, reasons and scientific principles are explained so that students understand how the answer is formed.

This is particularly useful for questions that ask students to explain, differentiate, give reasons, analyse an activity, interpret an observation or apply a concept.

How to Study Class 7 Science

Students should begin by understanding the concepts rather than memorising the NCERT answers. Read each concept page, study the examples and diagrams, and pay attention to the observations made during activities.

After learning a topic, attempt its questions without immediately checking the solution. Compare your response with the explained answer, identify what you missed and rewrite the answer in your own words.

Follow this sequence for every chapter:

Concepts → Activities → NCERT Questions → Teachoo Questions → MCQs → Case-Based Questions → Revision

Practising in this order develops both conceptual understanding and examination-writing skills. It also prepares students for competency-based questions in which the concept must be applied to a new situation.

Why Learn Class 7 Science with Teachoo?

Teachoo presents Class 7 Science in a structured, chapter-wise format. Complex ideas are divided into smaller parts and explained using familiar examples. This helps students understand the connection between scientific concepts instead of treating every answer as an isolated fact.

Students can use Teachoo for daily study, homework, classroom revision, unit tests, periodic assessments, half-yearly examinations and annual examinations. Parents can use the explanations to support learning at home, while teachers can use the additional questions for practice and revision.

Teachoo is useful for both the new NCERT Class 7 Science Curiosity book and the old NCERT Class 7 Science textbook. Select the chapter followed by your school, study its concepts and then practise the related questions.

Choose a chapter and start learning. Science becomes easier when every observation leads to a question—and every answer is understood, not merely memorised.
