Every year, tonnes of plastic waste and sewage wash up on the world’s beaches and riverfronts. There is plastic in the seas, plastic in the oceans, and plastic pretty much everywhere around us. 

As you rightly guessed, plastic is harmful to marine life, and so is any kind of pollution. Can you find a way to reverse all this harmful damage? How will you do it? We know for a fact that Bacteria, some of the smallest Microorganisms can easily break down waste such as dead animals and leaves.

To find out, you would have to love Science, and probably become a Scientist. In NCERT Class 6 Science book PDF, you will consider these questions and answer them yourselves. 

The Science book of Class 6th is more than just a collection of facts about life on Earth: it offers students a way of learning about the world, and is designed to test, reason and test again. Students will find how the NCERT 6th Science book explains the world and encourages them to develop ideas of their own. Chock-full of questions that ask for evidence, the books are a wonderful way to learn more about the natural world and the forces in it.

Get into the habit of taking very detailed notes that briefly summarize the idea in these books as only then you will be able to score the best marks. Students are recommended to continue this practice throughout the year and if they do not have this habit, then we recommend it a lot! Note-taking is a great way to understand the Chapter and revise it properly.

Chapter 1: Food – Where Does It Come From?

Many times, you have heard someone saying, " You are what you eat." Is that really true? Yes, it is. What you eat and consume plays a significant role in your good health. Samosas and fried snacks may be delicious, but should you eat them every day? Probably not.

Do some fruits and vegetables really prevent you from falling sick? Maybe not. But they do help you stay healthy. In this Chapter of NCERT Class 6 Science book PDF, you’ll find out the different types of food we eat, where they come from, and how to know what is right for your health.

A Chapter that will be useful in a lot of things in your future. Do not miss out on the essential knowledge that you must get in order to ensure that you are doing great in your upcoming Science Exam.

Chapter 2: Components of Food

Our body needs food for several reasons: to provide energy for all our activities, to provide building material for repair and mechanical strength and to ensure good health. The food we eat consists of several substances called Nutrients, and there are six major types of these. They are, namely, Carbohydrates, Vitamins, Proteins, Water, Fats and Minerals.

The second Chapter of NCERT Class 6 Science book PDF not only talks about the crucial role food plays in our bodies, but also what food is right to eat and how many factors affect the choice of food we eat.

Chapter 3: Fibre to Fabric

When you shop for your favourite dress or a pair of shoes, do you stop to think about what’s in it? A diverse number of materials and substances go into the making of a single dress or shoe. Some of these can be very commonly found, while some may be rare. But all of these are sourced from the surrounding environment around us.

This Chapter of the NCERT 6th Science book talks about the natural sources of fibres, how clothes are made and the use of synthetic fibres to manufacture certain clothes.

Chapter 4: Sorting Materials Into Groups

Take out a tube of colours and mix them all. What do you see? The rainbow of colours you get on your brush is simply a mixture of different paints: Green, Yellow, Orange, Red or Blue. The same applies to most of the things we see around us, and this is explained in this Chapter of the NCERT Class 6 Science book PDF.

Most things and objects around us are made of many different substances, while at times, it may also be composed of a singular material. Most of these materials have distinct properties and can widely differ in the way they look. A necklace made of gold looks distinctly different from a block of wood or a plastic toy. Materials, their various properties and how they can be categorised into different groups is discussed and explained in detail in this Chapter.

Chapter 5: Separation of Substances

A glass of cold Nimbu-Paani can feel extremely refreshing on a scorching hot summer day. This Nimbu-Paani or lemon juice is a mixture of Sugar, Salt, Lemon juice and cold water. So do you know what lemon juice is? Is it an element, a compound or a fibre? Not all substances are fibres or compounds -  some of these, like lemon juice, are mixtures.

Mixtures generally consist of two or more substances combined in varying proportions. Thus to know what, say Lemon juice is made of, you need to separate its components, as described in the fifth Chapter of NCERT Class 6 Science book PDF. Several phenomena, critical to students' understanding of the natural world, such as evaporation and condensation, are also described in detail.

Chapter 6: Changes Around Us

You have often seen people lighting fireworks to celebrate a happy occasion or a grand festival. These are certainly very beautiful to look at, but did you know that fireworks release a lot of gases when they are burnt? What makes the fireworks light up so brilliantly? Well, they are chemical changes.

The sixth Chapter of the Science book Class 6 NCERT introduces the concept of changes to students in Class 6. It explains how different changes around us can be grouped into categories: Reversible and Irreversible changes. Permanent changes such as the curdling of milk to give yoghurt or paneer are also talked about, and the Chapter asks students engaging questions such as: can salt-water be changed to just water again? The Chapter is a brief introduction to more complex ideas that students will eventually learn about in higher Classes.

Chapter 7: Getting to Know Plants

While going to school every day, you notice several trees and plants lined up along the way. You have probably seen flowers too. Flowers, plants and trees are a common sight around us. So why are trees and plants so important? This Chapter of the NCERT Class 6 Science book PDF explains why.

Students are taught what plants are and all the different parts of a plant. They learn that plants, unlike animals, cannot move to find their food. They, instead, make their own food with the help of their leaves and survive wherever they are. Plant parts and structures, such as roots, stems, leaves, flowers and shoots are also discussed, as well as why life on Earth would be impossible without plants.

A Chapter that helps students in realizing the importance of one of the most important natural resources, plants. We highly recommend students to go through all of this Chapter very carefully and relate it to the things that they see in their everyday life. By doing so they will be able to understand their surroundings better.

Chapter 8: Body Movements

Our bodies carry out different movements all the time, which are necessary for us to function well. Even if we sit and try not to move, our eyes continue to blink, our lungs keep taking in air, and our stomachs churn food. And when we move, run and walk, various kinds of bones in our legs, hips and hands facilitate the movement.

Hinge joints in our knees and ball and socket joints are two of the essential bones that aid in our movement. But all animals do not have bones like humans; they have other ways to move, such as in the case of snakes and snails. The 8th Chapter of NCERT Class 6 Science textbook defines the body movements of different animals.

Chapter 9: The Living Organisms - Characteristics and Habitats

Every living being we see around us has specific characteristics, which make them different from one another. Humans are a social creature and have the most developed brains, capable of performing complex activities. While animals and birds may not have such highly-evolved brains, they have their own set of bodily functions to perform, and each of them lives in their characteristic natural habitat.

Different habitats are suited for different types of animals. Animals which live on land (like humans) prefer terrestrial habitats while fish prefer aquatic habitats. Also, living beings are part of the biotic environment while non-living things are essentially abiotic components of the environment. The 9th Chapter of NCERT books for Class 6 Science details the types of organisms which live on our planet. 

Chapter 10: Motion and Measurement of Distances

This Chapter of NCERT books for Class 6 Science introduces students to motion and measurement. The vehicles on which we ride, the fans inside our houses and the birds flying high above are in motion. Motion is the state during which an object moves. When that object stops its motion, it is said to be in a stationary state.

Measurement is the method by which the dimensions of any tangible body can be calculated. There are many units of measurements which are followed by different countries worldwide. Also, there are many devices which are used in measuring. A weighing scale measures weight and a straight ruler measures length. 

Chapter 11: Light, Shadows and Reflections

Light makes everything visible around us. It is another crucial element that contributes to the existence of life on Earth. The primary source of light on our planet is the sun. Due to this reason, planets which are far away from the sun or any major star cannot support life.

An essential Chapter that is very essential and is useful even in the higher Classes. It has some of the most essential principles that need to be taught with a lot of patience and care and therefore needs a lot of observation and a keen will to learn too.

Light is also the reason why shadows and reflections are formed. A shadow is obtained when a solid object obstructs light. And a reflection is formed when light from a body hits a surface such as glass. The 11th Chapter of Science NCERT Class 6 PDF tells us more about light and its importance. 

Chapter 12: Electricity and Circuits

Without electricity, life in the 21st century would be dark. Every gadget we use nowadays is run with the help of electricity. Electricity is related closely with Magnetism, and the movement of charges inside an Electric Field causes Magnetic Fields to form. Various natural events like thunder and lightning and static electricity also involve Electric Charges and Fields.  

Benjamin Franklin and Michael Faraday were the two most famous Scientists who laid down the properties of Electricity and how it can be used for our benefit. When electricity flows through a path, the path is called an Electric Circuit (like a bulb connected to a cell). This Chapter of Class 6 Science NCERT PDF introduces the concept of Electricity to students.

Chapter 13: Fun with Magnets

Magnets exhibit one of the universal physical phenomena called Magnetism, which is in turn controlled by Magnetic fields. All celestial bodies like the Sun, Moon or our Earth have Magnetic fields on opposite poles. There are two major types of materials – Magnetic (iron, cobalt, nickel) and Non-Magnetic (rubber, paper, cloth).

One of the primary uses of Magnets is finding directions. In ancient times, when people only had compasses for navigation, Magnets were extremely essential. Also, an important property of Magnets is attraction and repulsion – similar poles repel and opposite poles attract. The 13th Chapter of NCERT Class 6 Science book PDF conjures different exercises, which helps students understand all the important properties of Magnets. 

Magnets are interesting things that have the potential of being one of the most enjoyable Chapters that you can ever come across too. Use the NCERT activities carefully and let your imagination lose so that you can make the most out of this Chapter.

Chapter 14: Water

Water, along with air, is the most crucial element that makes life on Earth possible. About 71 percent of Earth's surface is filled with water – which includes Oceans, Seas, Rivers, Ponds and Lakes.

Water bodies are the main source through which we receive water in our homes. The production of water is through a cycle, during which water from the surface evaporates, forms clouds and then falls as rain. This Chapter of Class 6 NCERT book Science makes students understand the importance of water and how we can use it wisely. 

Chapter 15: Air Around Us

Air is present everywhere in the Atmosphere. It is a collection of various gaseous Atoms and Molecules, which helps life survive on Earth.

Nitrogen, Oxygen, Water Vapour, Carbon Dioxide, Dust and Smoke are some of the major constituents of air. Other than being a life-giver, air also serves as a medium for sound to travel. The penultimate Chapter of NCERT books for Class 6 Science tells us about the significance of air and how each of its components is essential for life.

Chapter 16: Garbage In, Garbage Out

Garbage includes all the waste products which we do not use and throw away in bins. There are usually government workers who are paid to collect garbage from bins in front of our homes. These are then deposited in dumps in the outskirts of cities to be processed after that.

Due to the sheer amount of garbage produced by a city’s population every day, it often becomes a nuisance if garbage is not thrown away and collected properly. The last Chapter of Science Class 6 NCERT PDF informs students of all the environmental-friendly ways in which garbage disposal can be done to make the world a healthier place.
