That would be a chemical change because the firefly produces a bio-luminescent chemical. This chemical produces light which you see when the fire fly lights up!

Is a firefly giving off light a chemical or physical change?
It's not a change at all. It is simply what the firefly does. But it is a result of a chemical change within the firefly. A chemical reaction involves a transfer of energy. In this case, the energy would go into creating light waves from the molecules in the firefly, causing it to glow.
If a firefly glows in the dark is that a chemical or physical change?
It's a physical change. A chemical change is when a new substance is formed. A physical change is when something looks, feels, tastes, or smells different, but it's the same substance. You see the firefly is always glowing, it's just the fact that the human eye cannot see it because it is being over powered by the light of the Sun; but it's still the same firefly.
Is fire in a fireplace a physical or chemical property?
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
How could you test whether a chemical or physical reaction occurred?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds - Change of the state of the matter - A violent reaction with explosion or fire - Bubbling - Emitting a sound - Emitting a light----------------------------------------------------------------During a physical change the molecule composition is not affected.
