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 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 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 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.…
