Byperforming the experiments of CBSE Class 10 Science, students will understand concepts in a better way as they can now see the changes happening in front of their eyes. Their basics will become stronger as they will learn by doing experiments. Not only this, but their interest in Science subjects will also get generated. Students will develop questioning skills and start thinking from a scientific perspective. Here, we have provided all the necessary details that a Class 10 student should know about CBSE Class 10 Science practicals. From CBSE Science practical to lab manual, project work, NCERT lab kit manual and important questions, all the information is provided in the elaborated form further on this page for Class 10 students.

In the Class 10 board exam, Science practicals also carry marks. The Class 10 Science theory paper is for 80 marks, and 20 marks are allocated to internal assessment. The marking scheme for internal evaluation is shown below:

The practical should be conducted alongside the concept taught in the theory classes. In Class 10 Science, there are a total of 15 practicals in the syllabus. The list of these practicals is provided below.

Students can download the complete lab manual from the table below. The CBSE Class 10 lab manual is divided into 5 parts. The last part consists of project work in which a total of 111 projects are suggested. These projects will promote creativity and a spirit of inquiry in students. Also, it will help them understand the application of the Science subject. Moreover, each project is explained clearly so that students can perform them easily.

At the end of each experiment, a few questions are provided in the lab manual. These questions are given to test how much students have learnt from a particular experiment. So, students must answer all these questions. Below provided are a few of these questions. However, students will get the complete set of questions in the CBSE Class 10 lab manual PDF provided above.

The NCERT Class 10 Science manual kit provides activities on various chapters of Science subjects. The kit contains scientific and general items, chemicals, glassware, tools, etc. All the details of these tools and the methods of using them are described in the NCERT Class 10 Science Manual Kit. Various discoveries and inventions happened because of performing these experiments. Students will understand the concepts and synthesise their knowledge by doing these experiments. They can also connect the topic with the theory part that they have studied and discussed in the classroom. They will inculcate problem-solving strategies and group learning skills in themselves while performing the activities through kits. It also creates interest and motivates them to learn new facts.

Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force.[1] Physics is one of the most fundamental scientific disciplines.[2][3][4] A scientist who specializes in the field of physics is called a physicist.

Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest.[5] Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the Scientific Revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right.[a] Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms studied by other sciences[2] and suggest new avenues of research in these and other academic disciplines such as mathematics and philosophy.

Advances in physics often enable new technologies. For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons;[2] advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

The word physics comes from the Latin physica ('study of nature'), which itself is a borrowing of the Greek φυσική (phusikḗ 'natural science'), a term derived from φύσις (phsis 'origin, nature, property').[7][8][9]

Astronomy is one of the oldest natural sciences. Early civilizations dating before 3000 BCE, such as the Sumerians, ancient Egyptians, and the Indus Valley Civilisation, had a predictive knowledge and a basic awareness of the motions of the Sun, Moon, and stars. The stars and planets, believed to represent gods, were often worshipped. While the explanations for the observed positions of the stars were often unscientific and lacking in evidence, these early observations laid the foundation for later astronomy, as the stars were found to traverse great circles across the sky,[5] which could not explain the positions of the planets.

According to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, and all Western efforts in the exact sciences are descended from late Babylonian astronomy.[10] Egyptian astronomers left monuments showing knowledge of the constellations and the motions of the celestial bodies,[11] while Greek poet Homer wrote of various celestial objects in his Iliad and Odyssey; later Greek astronomers provided names, which are still used today, for most constellations visible from the Northern Hemisphere.[12]

The Western Roman Empire fell in the fifth century, and this resulted in a decline in intellectual pursuits in the western part of Europe. By contrast, the Eastern Roman Empire (usually known as the Byzantine Empire) resisted the attacks from the barbarians, and continued to advance various fields of learning, including physics.[16]

In sixth-century Europe John Philoponus, a Byzantine scholar, questioned Aristotle's teaching of physics and noted its flaws. He introduced the theory of impetus. Aristotle's physics was not scrutinized until Philoponus appeared; unlike Aristotle, who based his physics on verbal argument, Philoponus relied on observation. On Aristotle's physics Philoponus wrote:

But this is completely erroneous, and our view may be corroborated by actual observation more effectively than by any sort of verbal argument. For if you let fall from the same height two weights of which one is many times as heavy as the other, you will see that the ratio of the times required for the motion does not depend on the ratio of the weights, but that the difference in time is a very small one. And so, if the difference in the weights is not considerable, that is, of one is, let us say, double the other, there will be no difference, or else an imperceptible difference, in time, though the difference in weight is by no means negligible, with one body weighing twice as much as the other[18]

Philoponus' criticism of Aristotelian principles of physics served as an inspiration for Galileo Galilei ten centuries later,[19] during the Scientific Revolution. Galileo cited Philoponus substantially in his works when arguing that Aristotelian physics was flawed.[20][21] In the 1300s Jean Buridan, a teacher in the faculty of arts at the University of Paris, developed the concept of impetus. It was a step toward the modern ideas of inertia and momentum.[22]

Islamic scholarship inherited Aristotelian physics from the Greeks and during the Islamic Golden Age developed it further, especially placing emphasis on observation and a priori reasoning, developing early forms of the scientific method.

Although Aristotle's principles of physics was criticized, it is important to identify the evidence upon which he based his views. careful study of the history of science and math reveals the contributions made by older scientists. Aristotle's science was the backbone of the science taught in schools today. Aristotle published many biological works including The Parts of Animals, in which he discusses both biological science and natural science. Aristotle played an important role in the progression of physics and metaphysics, and his beliefs and findings are still taught in science classes today. The explanations that Aristotle gives for his findings are also simple.

When thinking of the elements, Aristotle believed that each of the four classical elements (earth, fire, water, air) had its own natural place.[23] Because of their differing densities, each element will revert to its own specific place in the atmosphere.[24] So, because of their weights, fire would be at the top, air underneath fire, then water, then lastly earth. He also stated that when a small amount of one element enters the natural place of another, the less abundant element will automatically go towards its own natural place. For example, if there is a fire on the ground, the flames go up into the air as an attempt to go back into its natural place where it belongs. Aristotle called his metaphysics "first philosophy" and characterized it as the study of "being as being".[25] Aristotle defined the paradigm of motion as a being or entity encompassing different areas in the same body.[25] Thus, a person who is at a location (A) can move to a new location (B) and still take up the same amount of space. This is involved with Aristotle's belief that motion is a continuum. In terms of matter, Aristotle believed that the change in category (e.g. place) and quality (e.g. color) of an object is defined as "alteration". But, a change in substance is a change in matter. This is also similar to the idea of matter today.
