Pulley System as a Simple Machine
What is a pulley? A pulley system uses an inextensible string. When one end of the string is pulled by 1 meter, the other end moves by the same distance. This demonstrates the concept of constrained motion or constrained length. Applying a force to one end of the string directly affects the motion at the…

Transformer Works on the Principle of Electromagnetic Induction
A transformer works on the principle of Faraday’s Law of Electromagnetic Induction. Let us understand how this phenomenon helps us increase and decrease the voltage in circuits using a transformer. This law is at the crux of the link between electricity and magnetism. It defines how current flows through a conductor because of a magnetic…

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.…

Why should schools have science laboratory equipment?
What is science laboratory equipment? Science laboratory equipment includes instruments and apparatus used to demonstrate scientific principles, helping students understand theoretical concepts and connect them to real-life phenomena. This equipment also allows for the validation and verification of scientific ideas. Successful experimental results reinforce classroom theories, translating abstract concepts into practical, observable experiences. In a…

How to Teach the Power of Hydrogen (pH)?
What is Power of Hydrogen (pH)? The power of hydrogen, or pH (also called the potential of hydrogen), measures the concentration of hydrogen ions in a solution. The formula for calculating the pH of a liquid is: pH = -log [H⁺] A higher pH indicates lower acidity and higher alkalinity in the solution. Conversely, a…

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 to Teach Wave Motion and its Properties?
Waves aren’t always visible. When you drop a pebble in water, it may look like the water is flowing outward, but that’s not the case. To understand what’s happening, you need to understand waves. If you place a cork in the water and drop a pebble nearby, you’ll see the cork bobbing up and down.…
