Observations

 * All capital letters on sheet
 * Mrs. Laguna is carrying a black marker
 * written in black

Background Information

 * ** Paper chromatography ** is an analytical method technique for separating and identifying mixtures that are or can be colored, especially pigments.
 * useful for separating complex mixtures of compounds having similar polarity, for example, amino acids
 * Mixture- **a substance made by mixing other substances together.
 * Solution**-a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
 * Chromatography-**the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates.
 * Frictional Distillation-** separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.

Inferences or Hypothesis
If the Penguin was stolen, the suspect would have his prints near the victim or on the note left behind.

Tests Performed
Chromagraphy

Data
Collected pens from everyone

Conclusion
Mr. beil is a suspect-has a anti-penguin poster

Observations

 * all test strips are leaking multiple colors

Conclusions
we will be able to tell by the color changes on the paper

Observations

 * Penguin left out in the hallway
 * caution tape around victim
 * unknown substance left by the victim

Conclusions
this liquid will tell us what substance it is

Observations

 * Mr. hovan had the same paper pieces
 * mrs Cravener matches the note writing
 * every 30sec measured

Inferences or Hypothesis

Tests Performed
Heating Curve

Conclusions
more than one substance is contained in the writing.

Observations

 * substance still clear
 * steam forming
 * substance is bubbling rapidly

Inferences or Hypothesis
If the substance is heated the liquid will separate

Tests Performed
Heating Curve 2 distillation

Data
Test tube A- milky/whitish yellow color Test Tube B- brownish/yellowish/whitish color Test Tube C- clear liquid

Conclusions
three different substances came out of the solution

Observations

 * Mrs. Craveners marker matches the prints on the ransom note
 * Cravener says she doesn't know about the murder

Inferences or Hypothesis
If the substrance is heated the liquid will separate and give us the final answer to "who done it"

Data
The print match one of the suspects

Conclusions
Mrs. Cravener is the crook who killed Mrs. Lagunas penguin
