How to prepare for a practical examination?
Practical examination is an essential component of school and college curricula, and students often feel nervous about it. While theoretical lessons have standardized preparation processes, practical lessons and exams have a relatively less common preparation strategy. Therefore, for students to succeed in these exams, it is important to focus on key essentials that must be…

The Modern Periodic Table – Periodic Table Trends and Properties
In the modern periodic table chart, the properties of elements follow a periodic pattern based on their atomic numbers. The atomic number, which represents the number of protons in an atom’s nucleus, increases by one for each subsequent element. This pattern is the basis of the Modern Periodic Table, established by Henry Moseley in 1913.…

How to Teach Kinetic and Potential Energy?
Energy as a function of work Kinetic and potential energy are a function of work. It is defined as the product of the force applied on a body and the displacement of the body caused by this force. Mathematically, it is expressed as: W = F × d where W represents work, F is force,…

How to Teach the Concept of a Coupled Pendulum?
What is a pendulum? A pendulum is a fascinating device that consists of a ball-shaped mass, known as the “bob,” suspended by a theoretically massless string from a fixed point. An extension of this is the coupled pendulum, which we shall study in a while. When you displace this bob from its starting position, it…

How are Composite Skill Labs Enhancing Learning Across Multiple Disciplines?
The Composite Skill Lab is enhancing learning; hence the Central Board of Secondary Education (CBSE) has adopted the same. They are continually adapting to developments in the field of education, and this is one of their landmark steps. These labs are designed to foster a multidisciplinary approach to learning, enabling students to gain practical experience…
