Regular and Diffused Reflection

Diffused reflection happens when light hits a rough or uneven surface and scatters in different directions….

Contact Force – Friction (Basics)

In this experiment, we study how a block moves when a force is applied to it. The block moves only…..

Fire Extinguisher

In this experiment we will perform a fire extinguisher demonstration by burning wood…

Simple Electroscope

In this experiment, we are going to perform a demonstration of charge transfer. We rub a metal rod with a cloth to generate negative charge on it….

Microorganisms Moist Soil – (Microscopic Examination)

In this experiment, we are going to observe mud water under a microscope….

Microorganisms Pond Water – (Microscopic Examination)

In this experiment, we are going to observe mud water under a microscope to detect the presence of microorganisms…

Laws of Reflection Of Light

In this experiment, a ray of light is directed onto a plane mirror placed on a white sheet of paper. The path of the incident ray and the reflected ray is marked using pins or a laser beam. A normal is drawn at the point where the incident ray strikes the mirror. Using a protractor, the angle of incidence and the angle of reflection are measured…………

Force and Deflection on Collision

In this experiment, a ball is rolled on a flat surface and then made to hit a wall placed at an angle…..

Effect of Water Quantity on Sound Pitch

Five glasses filled with different water levels were tapped gently to produce sound…..

Role of Air in Burning

In this experiment, a piece of burning charcoal is placed on an iron plate. Then a glass jar is put over it. The flame burns for a short time and then goes out. …….
