Thin layer chromatography is a quick and effective method of separating pigments within leaves. The pigments run clearly on the chromatogram with little outward spread, allowing Rf values to be calculated
and chlorophylls to be easily identified.

Light from a Hydrogen gas discharge tube is passed through a prism, the light is split into four visible lines. Each of these spectral lines corresponds to a different electron transition from a higher energy state to a lower energy state. Elements has a atomic emission spectrum, as shown e.g helium

Gas discharge tubes are enclosed glass tubes filled with a gas at low pressure, through which an electric current is passed. Electrons in the gaseous atoms first become excited, and fall back to lower energy levels, emitting light of a distinctive color in the process. Gas discharge tubes of helium.

Cellular Respiration : Bicarbonate indicator over time as the maggots release carbon dioxide during respiration,causes the solution to become more acidic and change color, typically from red to yellow. this demonstrates that the maggots are actively respiring and producing CO2 as a waste product.

Elodea densa “ Elodea Pondweed”- The plants will release bubbles of oxygen - a product of photosynthesis - which can be counted. A lamp with an LED bulb is set up at different distances from the plant in a beaker of water: an LED bulb is best as this will not raise the temperature of the water.

A ripple tank is used to measure and calculate frequency, wavelength and the speed of waves on the surface of the water. A ripple tank is a transparent shallow tray of water with a light shining down through it onto a white card below to clearly see the motion of the ripples created on water surface

Chromatography with black ink is a science experiment that separates the colors in black ink using water or alcohol to dissolve the ink and move it through filter paper. The result is a pattern of colored bands that shows the colors that make up the ink. 🖋️

The tornado in your bottle is caused by "centripetal force" – an inward-facing force that pulls an object or liquid toward the center of its circular path. The twister created in your bottle is caused by the water in the bottle spinning towards the center of the bottle, or vortex.#Physics
