In this project, students will explore the phenomenon of chemical luminescence by creating glowing solutions. They will learn about the chemical principles behind luminescence and how different chemicals interact to produce light.
If different chemicals are mixed in specific conditions, then they will produce a luminescent glow.

Gather all materials and wear safety gear.
Measure and pour 100ml of hydrogen peroxide into a beaker.
Add 50ml of distilled water to the beaker with hydrogen peroxide.
Slowly add 50g of sodium carbonate to the beaker and stir until dissolved.
In a separate container, dissolve a small amount of luminol in distilled water.
Gradually mix the luminol solution with the hydrogen peroxide solution while observing any changes.
Turn off the room lights to observe the luminescent effect.
Record observations and repeat with varying luminol concentrations.
The chemical reaction between luminol and hydrogen peroxide will produce a blue luminescent glow. The intensity of the glow may change with different concentrations of luminol.

Wear protective gloves and safety goggles. Handle chemicals with care.
Use photos of the glowing reaction in your display.
Explain the chemical processes behind luminescence.
Include a short video demonstration if possible.
Display the materials and equipment used in the experiment.
Luminescence is light produced by a substance not resulting from heat but from a chemical reaction.
The reaction releases energy in the form of light when electrons return to their ground state.
Yes, other chemicals can produce luminescence under specific conditions, such as in glow sticks.
