Acid–Base Experiments are practical science activities used to study the nature, properties, and reactions of acids and bases. In these experiments, different substances are tested to determine whether they are acidic, basic, or neutral.

Students commonly use indicators such as litmus paper, pH strips, or natural indicators like red cabbage juice, which change color depending on the acidity or alkalinity of a substance. Acids usually turn blue litmus paper red, while bases turn red litmus paper blue.

Another important acid–base experiment involves mixing an acid with a base, such as vinegar and baking soda. This reaction produces carbon dioxide gas, causing bubbling or fizzing, and demonstrates the process of neutralization, where an acid and a base react to form salt and water.

Reflection of light is the phenomenon in which light rays strike a surface and bounce back into the same medium instead of passing through it.

When a light ray hits a smooth, shiny surface (like a mirror or polished metal), it reflects in a definite direction. This type of reflection is called regular reflection. Rough surfaces cause diffuse reflection, where light scatters in many directions.

The Gravity Tower shown is a physics laboratory apparatus used to demonstrate and study free fall under gravity. It consists of a transparent vertical frame made of acrylic panels, allowing clear observation of motion. At the top, a release mechanism holds a small metal mass (often a plumb-bob–shaped weight) suspended by a thin thread or trigger system.

When released, the mass falls vertically through the tower solely under the influence of gravity. The open, clear structure ensures minimal air resistance and provides accurate visual tracking of the falling object. The apparatus is commonly used to measure time of fall, acceleration due to gravity (g), and to illustrate concepts such as uniformly accelerated motion.
