Science Fair Lab Report Sophia Tavakol 12/2/14 Ms. Davidson 6th period Rainbow Fire 12/5/14 I Abstract: What colors do different chemicals produce in a fire? Lucky for you, the purpose of this project was to see to see if the flames of a fire changes colors when chemicals are added to it. Since different types of atoms have different gaps between their energy levels, they make light of different colors when their electrons lose energy. The chemicals that combine to make these different colors are metal compounds that can burn. In our experiment, the flames did produce different colors. The sodium chloride produced an orange colored flame, the boric acid produced a yellow-green colored flame, the strontium chloride produced a red flame, and the copper sulfate produced a green colored flame. In the end of this project, our hypothesis was correct; if you put different chemicals in the fire, then it will create different colors (Helminstine). II Question: What colors are produced when chemicals are put in a fire? III Variables: Variables to keep the same: Time frame between putting the chemicals in the fire once the colors have worn out (10 seconds), amount of chemicals, time of day, location. …show more content…
The fire started to change to green flames soon after, lasting for 1 minute and 56 seconds. We then put the bamboo skewers that had the strontium chloride on it over the fire and watched the flames turn red for about 1 minute and 35 seconds. After the color died out we put the sodium chloride bamboo skewer over the fire and saw the flames turn orange lasting for 1 minute and 25 seconds. Finally, we put the boric acid bamboo skewer over the fire, which turned the flames a yellow- green color. The boric acid flames lasted for 2 minutes and 16 seconds. When the yellow-green color faded out, we poured the bucket of water on the fire to extinguish
