=Day 1 Report:=

Observations
Mrs. Laguna showed us where the note was located. This could mean that she planted the note and is the kidnapper. She could have easily taken and hid the penguins away from us. Mr. Lancos always comes in and out of the room, so he could've done while no one was around. I beleive that Mrs. Laguna and Mr. Lancos main suspects.

Background Information
Paper chromatography is an analytical method technique for separating and identifying mixtures that are or can be colored, especially pigments.
 * Paper Chromatography **

Inferences or Hypothesis
The person who has the same ink on the note as the pen, is therefore the thief.

Tests Performed
Chromatography tests completed (5)

Conclusions
The person who took our penguin used a black pen to write the noted. We examined and took observations as we tested our pens, this will lead to finally finding our kidnapper.

=Day 2 Report:=

Observations
The penguin was found in the front lobby Next to it was a flask filled with a mysterious liquid

Background Information
We have used the density test many times this year. We use it to find unknown substances. Our group aims to achieve success and find out who is the thief. We have also seen pictures of Mr. Hood and Mr. Beil with penguin pictures, leading to a possibility that they could be henchmen for the thief.

Inferences or Hypothesis
The person who has the same ink on the note as the pen, is therefore the thief. Mrs. Rhoades looks to have similar ink to as the note. We are hoping to find the identify the mysterious substance

Tests Performed
Chromatography tests completed (5) Density Test

Data
GC without liquid 17.5 GC with liquid 27

Conclusions
We are still unsure on who stole the penguin. Mr. Lancos looks to have some similarities between his pen ink and the note's ink, but at this time we are still unsure who the kidnapper is.

=Day 3 Report:=

Observations
The Heating Curve was performed today. The water was still until it hit boiling temperature and began to rise and bubble.

Background Information
We received another pen from Mrs. Cravener. We also completed the chromatography test.

Inferences or Hypothesis
We discovered ethanol has a boiling point of 78.5 We discovered that water has a boiling point of 100 The two substances where very close to the mystery substances we found in the liquid from the murder scene.

Tests Performed
Heating Curve Another pen and note

Data

Conclusions
We are still unsure on who stole the pen. We are seeing different colors in the ink. There is a little bit of each color on the paper sample.

=Day 4 Report:=

Observations
We put the liguid in a small test tube and heated it with the alchohal burner. Bubbles soon began, the liquid started seperating. The one liquid was a clear substance and the other liquid was a foggy faded yellow.

Background Information
The tests and labs will take a longer period of time. The substance separated into two iquids. One substance started to boil at around 79 degrees fahrenheit. the other was around 100 degrees fahrenheit.

Inferences or Hypothesis
I believe the marker is a compound substance. I believe this because the liquid quickly and easily separated.

Tests Performed
Fractional distillation

Data
**Pictures**

Conclusions
We have found two liquids in the origonal substance, this means it is a compound substance.

=Day 5 Report:=

Observations
As we attempted the flammability test, we saw that only one part of the substance was flammable. I think only one was flammable because it had a high enough concentration.

Background Information
The origonal test tube was heated. Bubbles rose and liquid evaporated. The evaporated substance went down a tube and in to a smaller test tube inside of a ice water beaker.

Inferences or Hypothesis
I predict that one of the substances will be flammable because alchohsl is a flammable substance

Tests Performed
Flammability Test

Data

 * Fraction || Flammability Test || Density Test ||
 * a || yes || 0.7 G/ML ||
 * b || no || .8 G/ML ||
 * c || no || .9 G/ML ||

Conclusions
My prediction was right and one of the liquids was flammable

"Who Done It" I beleive it was Mrs. Laguna. I think this because she has had the most and easiest access to the penguin. Also, no one would think about the victim beng the kidnapper, so she couldve easily gotten away with the crime.
