What are Personal Health and Community Health? Class 9 Science Personal Health  Personal health, which is primarily curvilinear in nature, necessitates individual attention. It is sporadic and episodic. The patient is frequently the centre of attention, and a multidisciplinary approach is used to treat him or her. Personal maintenance is frequently exclusive, necessitating patient consent. Similarly, when performing maintenance, doctors exhibit a higher level of priority and respect. Eating nutritious foods, drinking clean water, preserving personal and local hygiene, approving good lives and a healthy lifestyle, engaging in frequent and serene physical activity, and so on are all ways to maintain one's fitness. Community Health On the other hand, community care is mostly concerned with domestic difficulties and collection. It's continual and beneficial. The primary requirements are defensive care and the requirement for public participation. Although it is sensible and has lon

Mensuration Mensuration is a mathematical concept that involves, among other things, computing the areas, perimeters, and volumes of various geometrical objects. These shapes might be two-dimensional or three-dimensional. As a result, we learn to compute the areas, perimeters, and volumes of various two-dimensional and three-dimensional shapes. We accomplish so by employing algebraic equations and mathematical formulae. Mensuration is a branch of geometry that deals with the measurement of sides and volumes. It goes over the fundamentals and properties of a variety of figures and shapes. Mensuration, for example, can be used to calculate the length of cloth for sewing, the size of a wall to paint, or the amount of water needed to fill a tank. Click on  Types of Mensuration  Mensuration Worksheet for Class 6 I) Fill in the blanks: With each side 12cm, perimeter of triangle is _______. With all sides, 6 cm, the area of a square is______.

What are the characteristics of matter?   Everything around us is made up of small particles known as matter, as we all know. These particles have a few distinguishing characteristics that we will discuss. These characteristics can be divided into two categories: physical and chemical . We recommend going over the differences between physical and chemical changes first for a straightforward separation between the two groups. You can brush up on your concept by visiting our blog . The physical and chemical properties of matter are now dependent on how the properties of the substance change, in the same way that physical and chemical changes are dependent on how the properties of the substance change. It does not need to undergo any changes or transformations in order to identify the physical properties of matter. Chemical qualities of matter, on the other hand, necessitate the transformation of substances into other forms of matter. Physical Properties of Matter Matter's physical qu

Class 7 Science Motion and Time What is motion? The motion of an object is defined as the change in its position with respect to time. When the position of an object does not change with respect to time, the object is said to be at rest or stationary.  What is the difference between uniform and non-uniform motion? The differences are- Uniform motion It is a type of motion wherein the object moves in a straight line. Its velocity remains unchanged along that straight line, irrespective of the time duration. It occupies equal distances at equal time intervals. Uniform motion has zero acceleration. The uniform motion and the actual speed of the object are identical. The equal distance at an equal interval of time. The distance to time graph is a straight line. Non-uniform motion Contrary to Uniform motion, Non-Uniform Motion is a type of motion wherein the object moves at different speeds and does not cover the same distance at equal time intervals, irrespective of the duration of the t

Types and Symptoms of Weeds  Weeds are undesirable plants that grow alongside crops. These weeds provide nutrients to the crops while also reducing the number of nutrients available to the crops, hindering their growth. To promote plant growth, the growth of these weeds must be restricted. What are the most common weed types? Weeds are divided into two types: annual and perennial. Annual weeds are only spread by seeds. They normally have a brief growing season and produce a lot of seeds. Annual grasses (Pova anva), green foxtail (Cetaria viridis), and chickweed are the most common species (Stellaria media). Perennial weeds are both prolific and spread vegetatively. Rhizomes, tubers, and stems are all used to disseminate them. As a result, avoiding this category is particularly tough. Even chemical control is frequently ineffective. Quackgrass (Elimus rippens), Johnson grass (Sorgam halfpens), dubery (Rubus cicius), and dandelion are all common perennial weeds (Taraxacum officinalis).

Directions and Maps? Class 2 EVS Cardinal Directions are compass points that assist us in navigating or finding directions. North, East, West, and South are the four cardinal directions. The initial letters N, E, W, and S are commonly used to represent these directions What exactly is a compass? What is the purpose of a compass? When we can't find our path, we can use cardinal directions to guide us. We use a compass to understand the directions around us. It is a tool that assists us in determining directions. Because a compass needle always points north, we can readily determine where East, South, and West are. When you're alone and in an area that isn't densely populated, a compass can be quite useful. Mountains, forests, and oceans are examples of such places. Because there are no routes or highways on the open sea, ships and boats must rely solely on compass directions to achieve their destinations. What exactly is a map? A map is a drawing of a part of the Earth’s su

Neutralization Reaction Definition Class 10 Science A neutralization reaction occurs when an acid and a base react together. As acids and bases react, salt and water are produced as byproducts. Energy is also created throughout the process. The general equation for the neutralizing reaction is as follows: Acid + Base → Salt + Water Examples of Neutralization Reactions Examples of neutralization reactions are given below: 1. Sodium chloride and water are made from a combination of sodium hydroxide and hydrochloric acid. NaOH + HCl → NaCl + H2O 2. In the case of indigestion, milk of magnesia, a base, is administered as an antacid to neutralize the excess acid created in the stomach. Mg(OH)2 + 2HCl → MgCl2 + 2H2O Acids, Bases, and Ions When an acid dissolves in water, it creates positive hydrogen ions (H+) and negative nonmetal ions. (Ions get charged atoms that have lost or gained electrons.) An example of an acid is hydrochloric acid (HCl). HCl creates positive hydrogen ions and negativ

Erosion of Soil The erosion of topsoil is referred to as erosion. Deforestation, overgrazing, excessive use of fertilisers or pesticides, precipitation flow, landslides, and floods are all possible causes of erosion. What are the soil conservation methods? Mulching - Mulching aids in the retention of moisture in the soil. Mulching is the practise of covering undeveloped area with organic debris such as straw. Contour Barriers — Contour barriers aid in the prevention of rain-induced erosion. Stone, grass, or dirt connected to the contour forms the contour barrier. To store water, a trench has been dug in front of the dam. Dams, such as rock dams , can impede the flow of water. As a result, rocks are arranged to create a dam. Dams like these impede water flow. As a result, dirt and soil are not lost. Terrace Cultivation : In steep places, terrace cultivation is utilised to decrease erosion caused by water flow. To maintain a flat surface for growing crops, the plots are built in terrac

Equivalent Fraction Class 7 Maths When fractions are reduced to their simplest forms, equivalent fractions have the same value in their numerators and denominators . Example to convert a fraction into its simplest form To reduce a fraction to its most basic form, divide both the numerator and the denominator by a common number. Repeat the process until no single number can divide both the numerator and the denominator. Consider the fraction 2/4 as an example. Both the numerator and denominator can be divided by two, as we can see. As a result, we divide 2 and 4 by 2 and substitute the quotients of each division for the numerator and denominator. Because 2 divided by 2 yields a quotient of 1, 2 is replaced with 1. Similarly, the number 4 is replaced with the number 2 since 4 divided by 2 yields a quotient of 2. As a result, the most basic version of 2/4 is 1/2. Fraction Exercise for practice I. Fill in the blank to make the fractions equivalent: 24/__ = 4/1 220/__ = 20/11 20/40 = ___/2

Difference between Fertilizers and Manure  It is made by depositing plant and animal wastes in pits in an open area. It is an organic compound formed by the breakdown of plant or animal faeces. Because it is probably insoluble in water, it is slowly absorbed by the soil and plants. It provides fewer plant nutrients than fertilisers. It enriches the soil with humus. It is not harmful to the soil and, in the long term, enhances soil quality. It is cost-effective since it may be simply made from decaying plant and animal waste. It is created in factories by a chemical process. It is a synthetic or industrially-produced substance that contains plant nutrients. It dissolves easily in water and is promptly absorbed by the soil and plants. It contains more plant nutrients than manure. It does not add humus to the soil. Excessive fertiliser application can degrade soil quality and damage soil organisms. It is expensive because it is manufactured in factories by machines. Tag - online classes f

Short Essay on Pollution for Kids The introduction of any impure substance into the environment, whether in the form of a solid, liquid, or gas, is referred to as pollution. Pollution may contaminate the air, water, and land, resulting in a filthy environment. Chemical particles harm the environment as well. Honking and excessively loud sounds contribute to noise pollution. When artificial fertilisers are mixed with the soil, it results in land pollution. Garbage disposal in open areas pollutes the environment and spreads a number of diseases. Pollution has a negative impact on humans, animals, birds, and the environment. Pollution of the water is caused by the removal of dirty particles from factories. Pollution is caused by improper sewage management, which can be avoided by covering drainage lines. Groundwater is contaminated by metals such as arsenic and mercury. Click for know more Pollution Tag -  online classes for school students, pollution essay, short essay on pollution

What is Global Warming? Global warming occurs when the average global temperature rises as a result of increased greenhouse gas emissions. Greenhouse gases such as carbon dioxide, methane, and ozone capture sun energy. Furthermore, the greenhouse effect is increased when polar ice caps and sea ice melt. Sea levels are rising due to the melting of the polar ice caps. Furthermore, the greenhouse effect is increased when polar ice caps and sea ice melt. This is because ice reflects 50 to 70% of the sun's rays into space, whereas when there is no ice, solar radiation is absorbed. Seawater reflects only 6% of the sun's light back into space. Greenhouse gases aren't always dangerous. In reality, life on Earth depends on the greenhouse effect. Without this effect, the sun's rays would be reflected back into the atmosphere, freezing the earth and making life impossible. However, when large amounts of greenhouse gases are trapped, catastrophic effects result. A number of thin

Importance of Rivers Rivers carry nutrients and areas around the earth. It plays an important role in the water cycle of rivers and acts as a drainage channel for surface water. This leaves about 75% of the Earth’s surface. Rivers provide food and habitat for many living things on earth. In addition, rare trees and plants grow along the rivers. Otters, ducks, and beavers build houses along the river. Plants such as Buller and reeds grow along the river. Some animals use the river for food and drink. Birds like Kingfishers eat small fish from the river.  Animals such as deer, lions, and elephants drink water from rivers. Animals like bears fish from rivers. The Deltas River is home to a wide variety of wildlife. Mammals, birds, and insects use the delta for their homes and food. Provides rivers, routes, and travel routes for trade, exploration, and recreation. The valleys and plains near the rivers provide fertile soil. Farmers in arid areas irrigate their crops with water from nearby r
