Complete Explanation of CBSE Notes
We have learned about the natural numbers from 1 to 10. Whole numbers are the set natural numbers including with zero. 0 is the smallest whole number.
Whole numbers are 0, 1, 2, 3, ……… All natural numbers are whole numbers, but all whole numbers are not natural numbers. Please refer Whole Numbers Class 6 Notes for more revision notes.
A number is a mathematical value used to count and measure different objects. With the help of the numbers we all are able to add, subtract, divide and multiple.
Here we will be learning how to compare numbers, expand the number and also learn about the largest and the smallest numbers. Please refer Knowing Our Numbers Class 6 Notes for more revision notes.
CBSE board is an organization introduced by the government of India, which is designed to enhance and to support both central and state educational management. The main aim of this organization is to provide additional information about the subject through practical knowledge instead of theoretical.
These notes are widely helpful for all students, as it provides the best explanation and important questions for better performance in their Exams. Apart from the questions, the CBSE Class 6 Maths Notes also include multiple choice questions and other objective questions where students can practice by solving more number of problems.
Wastewater is defined as used water. Used water is either rich in lather, mixed with oil, black– brown water that passes through the drains from sinks, toilets, laundries, showers, is dirty. We can reuse the wastewater by removing the pollutants.
Many products in our day to day life are obtained from forests. Forest is an environment which is a place of living for micro-organisms, plants, and animals. The uppermost layer of the forest is formed by trees and followed by shrubs. The lowest level of vegetation is formed by herbs. These various layers of vegetation provide shelter and food for insects, animals, and birds.
There are various components in a forest. These components are interdependent on each other. Forests grow, changes, and regenerates. A place where living organisms, air, soil, and water interact with one another. Soil erosion is protected by the forest. Forest-dwelling communities consider forest as a lifeline. The quality of air, water cycle, and climate are influenced by forest. Please refer Forests: Our Lifeline Class 7 Notes for more revision notes.
Water is important for all living beings. Survival without water is impossible. It plays a significant role in the existence of life. There are three forms of water viz solid, vapor, and liquid. Water cycle maintains water but many parts of the globe face scarcity of water due to its uneven distribution. Majorly as a result of human activities.

White light consists of seven colors. The path in which light travels is a straight line. A smooth or shinning surface that forms images by reflection of light is called a mirror. Types of images formed with mirrors –
Representation of electric components is very easy with the help of symbols. Drawing a circuit diagram is done conveniently with the help of these. Heating effect of the current is defined as, the heating of wire due to the flow of electric current through it. When the electric current is flowing through the wire, it acts as a magnet. It has several applications. Some wires are made of unique materials.
Such wires melt rapidly and when a large electric current is passed through them they break. One major example of such material is an electric fuse. Electric fuses prevent fire as well as damage to any electric appliance. An electromagnet is defined as an insulated wire coil carrying current is wrapped around an iron piece. Please refer Electric Current and Its Effects Class 7 Notes for more revision notes.
The basic unit to measure speed is meter per second. Time can be measured with periodic events such as a periodic motion of the pendulum. This is used in watches and clocks. We can represent motion in a pictorial form by the distance-time graph. When an object is moving with at a constant speed, the distance-time graph is a straight line. Please refer Motion and Time Class 7 Notes for more revision notes.
All living organisms reproduce to multiply. The reproductive part of a plant is flower. It is either unisexual or bisexual. When a flower has only female reproductive parts or male reproductive parts, it is said to be a unisexual flower. When a flower has both reproductive parts i.e male and female together, it is called a bisexual flower. The female gametes are present inside the ovule whereas the male gametes inside the pollen grains. Sexual reproduction and asexual reproduction are the modes of reproduction in plants. The asexual methods are fragmentation, vegetative propagation, budding, and spore formation. Please refer Reproduction in Plants Class 7 Notes for more revision notes.
