Why does this phenomenon happen?

When electrons are heated they either stay where they are or they jump up to the next energy level. Resulting in a color change.

How did you do it?

17perezcd109 — 2013-10-18 16:34:50 UTC

We dipped a popsicle stick into a chemical, and held the sick in an open flame.

What happened in your experiment?

17trebilba255 — 2013-10-18 16:35:06 UTC

When we burned the sticks that where soaked in the chemicals the flame changed colors

How did you determine your unknown?

17trebilba255 — 2013-10-18 16:36:02 UTC

We burned the stick with the unknown chemical on it to see what color it produced then we compared it to what the other chemicals produced and the unknown produced the same color as sodium.

We are lighting chemicals on fire to see what color they produce
