Flame Test Lab Report by Sandy Tran [Student FVHS]

What is it that you are doing?

We are burning different types of chemical. We're observing the different colors that appear in the flame.

Why does the phenomenon happen?

How did you do it?

17lina117 — 2013-10-18 16:30:22 UTC

We did it by using a Bunsen Burner and soaking a popsicle stick in an element.

We then placed the soaked popsicle stick in the Bunsen Burner, in which as a

result, emitted a color.

What happened in your experiment?

How did you determine your unknown?

Colors

17transn256 — 2013-10-18 16:33:45 UTC

These are some examples of the colors we will see when we are doing this experiments. In this image they were burning different metals, but in our experiment we will be burning chemicals. The outcome is similar to this.

Period #2

17transn256 — 2013-10-22 16:40:29 UTC

We determined our unknown by looking at the color that appeared and compared the color to the other chemical's color,

and if our unknown's color matches the decription we had for the chemicals.

Then we assummed that our unknown chemical was the same one.

In our experiment we turned on the bunsen burner, and burned some

elments to see what colors would appear in the flame. For example, we examine what color

that appeared in the flame, if it was orange, red, yellow, or even green. We just compared the

color of our unknown with our description that we wrote down for the elments.

The phenomenon happens beacuase, the electron inside the element

gains enough energy to cause it to go to the exciting stage and then, it bounced

back to the ground stage emmiting a color as the energy dies down in the element.

Which ESLR was addressed in this activity?

17transn256 — 2013-10-23 16:27:32 UTC

We think the ESLR that was addressed in the activity was critical thinker. We think critical thinker was the ESLR in this activity beacuase, we had to think about our unknown element

by comparing and contrasting the color of our unknown element to the description we wrote down for the other element's color, and draw a conclusion to which element it was.
