Chapter 1 contains an integer study. In the previous class we learned about whole numbers and integers. Now, we will study more about integers, their properties and operations. Similarly, addition and subtraction of integers, addition and subtraction of integers, multiplication and division of integers, multiplication and division of integers.

###### Chapter 2: Nutrition in Animals

Chapter 2 of the NCERT Textbook deals with fractions and decimals. You learned about fractions and decimals in addition to addition and subtraction operations in the previous sections. Now we study multiplication and division operations on decimals along with fractions.

Similarly, multiplying a fraction by a fraction, multiplying a fraction by a fraction, dividing a fraction by an integer, dividing a fraction by a whole number, multiplying the decimal by 10,100, 100, and so on. Other things include multiplication of decades. Multiplying the decimal by 10, dividing the decimal by 10, 100, 1000, etc., divides the decimal by the whole number.

###### Chapter 3: Fibre and Fabric

Chapter 3 of the NCERT Textbook deals with data management. In your previous classes, you worked with a variety of data. You learned how to collect data, tabulate it and put it as a bar graph. Now in this chapter, we take another step to learn this. This chapter covers topics such as data collection, organization of data, representative values, arithmetic mean, big data mode, median, use of bar graphs for a different purpose, scale, likelihood and probability.

###### Chapter 4: Heat

Chapter 4, NCERT Textbook Simple Equations Solving an Equation with an Equation. In solving more equations we learn to convert a number, that is, to move it from one side to the other. Instead of adding or subtracting the equation we can move the numbers from both sides. We then study the practical situation from solutions to equations, the application of general equations.

###### Chapter 5: Acids, Bases and Salts

This chapter is about lines and angles. This chapter examines related angles, complementary angles, complementary angles, adjacent angles, linear pair, vertical opposing angles, lines connecting lines, cross-diagonal, cross-diagonal angle, horizontal lines, transverse lines.

###### Chapter 6: Physical and Chemical Changes

The subject of the triangle and its property is discussed in Chapter 6 of the NCERT textbook. The triangle is a simple closed curve made up of three consecutive sections. It has three corners, three sides and three angles. It is a right triangle on the right, the height of a triangle, the exterior angle of a triangle and its property, the total property of the angle of a triangle, the sum of the two distinct triangular equations and isosels, the sides of the whole triangle of length. . Angular triangle and Pythagoras property.

###### Chapter 7: Weather, Climate, and Adaptations of Animals to Climate

This chapter is about the congress of triangles. If the two shapes and sizes are exactly the same, they are called greetings. Other related topics include plane toys, compliments between line segments, angular greetings, triangle greetings, triangle greetings criteria, right angle triangles greetings.

###### Chapter 8: Winds, Storms and Cyclones

Chapter 8 of the NCERT textbook deals with comparative volumes. Another way to compare equivalence ratios and quantities is to understand percentages, convert percentages into fractions, convert decimals to percentages, convert percentages into fractions or decimals. Other interesting things are the fun of forecasting, percentage explanation, how much should be changed, ratio of percentages, percentage increase or decrease, profit or loss percentage, charge on borrowed money, or common interest.

###### Chapter 9: Soil

The subject of rational numbers is discussed in Chapter 9 of the NCERT textbook. This includes positive and negative rational numbers, rational numbers on the number line, rational numbers in the standard form, comparison of rational numbers, rational numbers between two rational numbers, operations on rational numbers.

###### Chapter 10: Respiration in Organisms

The topic of practical geometry is discussed in Chapter 10 of the NCERT textbook. You know so many shapes. You learned how to make some of the previous classes. For example, you can draw a line segment of a given length, a line perpendicular to a given line segment, an angle, an angle couplet, a circle, and so on. Now, you will learn how to draw parallel lines and some types of triangles. . The topic covered in this chapter is to construct a line parallel to a line through the construction of different triangles.

###### Chapter 11: Transportation in Animals and Plants

This chapter is about general interest. In 6th grade, you have already learned the perimeter of plane figures and the areas of squares and rectangles. If the circumference is the distance around the closed figure, then the area occupies the plane or the closed figure. In this class, you will learn about the perimeter and some other flat-shaped areas.

###### Chapter 12: Reproduction in Plants

In Chapter 12, algebraic expressions in the NCERT textbook find the values ​​of the expression, rather than the sum and subtraction, multiplication, words, monomials, biominerals, trinomials, polynomials, etc. of an expression.

###### Chapter 13: Motion and Time

Subject and powers are discussed in Chapter 13 of the NCERT textbook. Expansion is sometimes the product of rational numbers. Here are some concepts, multiplying forces with a single base, dividing forces with a single base, taking the energy of a single force, multiplying powers with a single exponent, powers with a single exponent. Divide, Decimal Number System, Express Large Numbers in Standard Form.

###### Chapter 14: Electric Current and its Effects

This chapter is about symmetry. Symmetry means that when you bend, turn, turn, or slide in some way, one shape becomes like the other. For two objects to be symmetrical, they must be of the same size and shape, with one object already having a different orientation. An object may also have a face-like symmetry. The topics covered in this chapter are the symmetry lines of the general polygons, rotation symmetry, line symmetry, and rotational symmetry.

###### Chapter 15: Light

In Chapter 15, the visualization of solid shapes in the NCERT textbook creates plane figures and traps to create solids, faces, edges, corners, 3-D shapes, solids on flat surfaces, oblique drawing, and isometric sketches. Some of the concepts covered in this chapter include the ining of concrete objects, looking at different sections of solid, another way of shadow play.

###### Chapter 16: Water – A Precious Resource

All living things need water. This chapter was added to educate students about water conservation. The chapter begins with how much water is available on Earth. Then it talks about the water cycle and the forms of water. It then states that groundwater is an important source of water, so we must use it wisely. Apart from this, the concept of water shortage and water management is explained. This chapter also sheds light on the roles humans can play in protecting the effects and effects of water scarcity on plants.

###### Chapter 17: Forests – Our Lifeline

The chapter states that the forest is a system of various plants, animals and microbes. The different parts of the forest are interdependent. Interaction between soil, water, air and organisms takes place in the wild. We must protect our forest and plant new trees in order to maintain proper balance in nature. Otherwise, it will seriously affect our environment.

###### Chapter 18: Wastewater Story

Water is the lifeblood of humans and animals on earth. As it is emphasized, what is sewage, is the treatment of contaminated water, sewage treatment plants, improved housing practices, sanitation and disease, alternative arrangements for wastewater disposal, and sanitation in public places.
