Chapter 1 The Ever-Evolving World of Science
The first chapter is an introduction to the wonderful world of science in Class 7. It describes topics in different interconnected fields of science, from physics and chemistry to biology and earth sciences. It tells you that the book covers properties of materials, electricity and circuits, physical and chemical changes, irreversible and reversible changes. You will also study biology of animals and plants, time and motion, light and shadows and the Earth, Moon, and the Sun. Have fun!
Chapter 1 The Ever-Evolving World of Science
Chapter 2 Exploring Substances: Acidic, Basic, and Neutral
In this chapter you will learn about different types of natural indicators and how to use them to identify acids, bases and salts. Then you will learn about the concept of acid base neutralisation and how it applies to practical situations.
Chapter 2 Exploring Substances: Acidic, Basic, and Neutral
Chapter 3 Electricity: Circuits and their Components
This chapter teaches you the basics of electric circuits and its components. You will learn about the components of electric circuits like electric cell, battery, electric lamp, LED lamps, electric switch along with their symbols and how they work together in an electric circuit. You will also learn about the conductors and insulators of electricity.
Chapter 3 Electricity: Circuits and their Components
Chapter 4 The World of Metals and Non-metals
You will learn about metals and non-metals in this chapter. You will get familiar about the properties of materials like malleability, ductility, sonority, conduction of heat, conduction of electricity etc. You will also learn about the effect of air and water on metals. The chapter ends with a brief discussion on the importance of non-metals.
Chapter 4 The World of Metals and Non-metals
Chapter 5 Changes Around Us: 5 Physical and Chemical
The most important part of this chapter is to be able to distinguish between physical and chemical, reversible and irreversible changes. You will learn about rusting and combustion including the necessary conditions for each. The chapter describes the burning of a candle and how it includes both physical and chemical changes. The chapter ends with a description of physical and chemical changes occurring in nature.
Chapter 5 Changes Around Us: Physical and Chemical
Chapter 6 Adolescence: A Stage of Growth and Change
This chapter talks about the changes that take place during adolescence in boys and girls. It describes the physical, biological, and emotional changes during adolescence and encourages you to maintain a healthy life and avoid any associated dangers.
Chapter 7 Heat Transfer in Nature
You will learn about the three ways in which heat is transferred from one place to another — conduction, convection, and radiation. You will do experiments in which you will see these phenomena in practice. At the end of the chapter, you will learn about the water cycle in detail, which is very important.
Chapter 8 Measurement of Time and Motion
This chapter describes the different ways of measuring time since ancient times. A simple pendulum is one of the most important concepts in this chapter. You will then get introduced to the concept of speed and Uniform and Non-uniform Linear Motion. You will get numerical problems from this chapter, hence practice them well.
Chapter 9 Life Processes in Animals
In this chapter you will learn about the human anatomy in detail and essential life processes such as nutrition, circulation, respiration, excretion, and reproduction. You will also learn that different animals have different breathing mechanisms adapted to suit their habitats.
Chapter 10 Life Processes in Plants
You will learn about the life processes of plants such as favourable conditions for plant growth, where they obtain their food from, photosynthesis, transport of water, minerals and food in plants, respiration in plants etc.
Chapter 11 Light: Shadows and Reflections
The chapter begins by talking about the natural and artificial sources of light. You will learn that light travels in a straight line, and about transparent, translucent, and opaque materials. You will learn about more interesting phenomena like shadow formation, reflection of light, characteristics of images formed by a plane mirror and lastly, you will create a working model of a pinhole camera! Have fun with all this!
Chapter 12 Earth, Moon, and the Sun
The most important parts of this chapter are the rotation of the Earth about its axis, revolution of the Earth around the Sun, solar eclipse and lunar eclipse.
