What is it that you are doing?

17limbachrc206 — 2013-10-18 17:57:26 UTC

We are burning chemicals on popsicle sticks over a flame.

Why does this phenomenon happen?

17limbachrc206 — 2013-10-18 17:57:51 UTC

Because the electrons get excited and then the energy is emitted in the form of various colors. Basically, from the ground state,
the electrons then get excited and then go into an excited state
which makes them bounce off the hook and then their energy
levels will go up, which to the human eye is in the form of color.

How did you do it?

17limbachrc206 — 2013-10-18 17:58:50 UTC

Using Coffee Stirrers that were dipped in certain chemicals, we
used the bunsen burner to lit those sticks up and then viewed
the color that was given off of the chemicals that were being burned.

What happened in your experiment?

How did you determine your unknown?

17limbachrc206 — 2013-10-18 18:00:09 UTC

Our unknown ion was Lithium. The unknown substance had the same coloring
as Lithium. Though there were many different shades of red, there was the specific shade of dark red that was only in Lithium.

Sodium (Na+)

17nguyentn239 — 2013-10-23 17:57:26 UTC

The color was a bright yellow-orange.

Potassium (K+)

17nguyentn239 — 2013-10-23 17:58:46 UTC

Its color was a really light pinkish orange.

Lithium (Li+)

17nguyentn239 — 2013-10-23 17:59:55 UTC

It was a really bright reddish looking pink.

Calcium (Ca2+)

17nguyentn239 — 2013-10-23 18:00:53 UTC

This chemical was a light orange.

Strontium (Sr2+)

17nguyentn239 — 2013-10-23 18:01:32 UTC

This color was a bright orange-red.

Barium (Ba2+)

17nguyentn239 — 2013-10-23 18:02:48 UTC

The color was lime green.

Copper II (Cu2+)

17nguyentn239 — 2013-10-23 18:03:41 UTC

This was a darker lime green.

Lead II (Pb2+)

17nguyentn239 — 2013-10-23 18:04:19 UTC

It was a light blue and it had sparks.

Unknown chemical (Lithium)

17nguyentn239 — 2013-10-23 18:05:20 UTC

The color was a really bright hot pink with some red.

Which ESLR does this represent?

In many different ways, creating this Padlet wall emphasizes critical thinking as well as effective communication.
In using current technology, students are able demonstrate a smarter way of thinking in a modern way that is
easier to access and more fun too! Communicating with the other lab partners allow us to balance opinions and
gives a stronger sense of intelligence when there are many mingled ideas.
