= Day 1 Report: =

Observations:

 * Penguin was taken early this morning
 * A note was left
 * Black felt pens were collected from suspects
 * Hood had penguin picture on his board
 * Bile had penguin picture hanging on his wall
 * Paper Chromatography is being used to test out the writing

Background Information:
**Solution**- "a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)." **Paper** **Chromotography**- " Paper chromatography is an analytical method technique for separating and identifying mixtures that are or can be coloured, especially pigments. This can also be used in secondary or primary colours in ink experiments."
 * Mixture**- "a substance made by mixing other substances together."
 * Fractional** **Disillation**- "Fractional distillation is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which one or more fractions of the compound will vaporize."

Inferences or Hypothesis
I believe Mrs. Kirschman's stole the penguin since her pen test was the most suspicious.

Tests Performed
chromotograhpy test
 * Samples of each black pen were drawn on the chromotograhpy paper 2 cm from the end
 * Each piece of paper was dipped in rubbing alcohol
 * Papers sat overnight drying on paper towels

Data

 * Kirschman**- No color change
 * Lancos**- had blue, pink, and purple color change
 * Cravner**- had a blue and orange color change
 * Hood**- had a blue and black color change
 * Rhodes**- had a blue, pink and purple color change

Pictures
//Ransom note////Mr. Hood suspicion// //Mr. Bile's Poster////Data//

Conclusions
All pens collected had a different outcome from the paper chromotography test.

=Day 2 Report:=

Observations:
Penguin was found in hallway with poison next to him.
 * Another note was left
 * Two papers (Rhodes and Lancos) have a green to purple mark
 * Cravner's paper is blue to orange marks
 * Hood's paper went from terquise to dark blue/purple
 * Kirschman's paper made no color changes in the paper

Background Information:
> -Cravner's paper is blue to orange marks > -Hood's paper went from terquise to dark blue/purple > -Kirschman's paper made no color changes in the paper
 * Penguin was taken early yesterday morning
 * A note was left
 * Black felt pens were collected from suspects
 * Hood had penguin picture on his board
 * Bile had penguin picture hanging on his wall
 * Paper Chromatography is being used to test out the writing
 * 5 testes were performed
 * -Two papers (Rhodes and Lancos) have a green to purple mark
 * Note test did not match any of the other pen tests

Inferences or Hypothesis
I believe that the pen used to write the anonymous has not been found yet since the tests taken have not shown any signs of matching to the pen used for the note.

Tests Performed:

 * Paper Chromotagraphy on pens test
 * Paper Chromotagraphy on the note
 * Density test

Data:

 * __Density Test__**
 * Empty Cylinder**: 17.7 grams
 * Cylinder with 10 ml of wa**ter: 26.3 grams
 * Cylinder with 10 ml of water - empty cylinder** - .86 grams

Conclusions
No Pens matched the note left behind about the penguin

=Day 3:=

Observations

 * condensations gathered in test tube
 * bubbling & fizzing in test tube
 * boiling in test tube
 * liquid collected in collection tube

Background Information

 * Another pen (owned by Mrs.Cravener) was discovered and its chromatography test matched the ransom note's chromatograohy test
 * Water has a boiling point of 100 degrees Celsius

Inferences or Hypothesis

 * Mrs.Laguna framed Mrs.Cravener with the mystery pen that matched the ransom note because Mrs.Cravener acted innocent when confronted.

Test Performed
**The Heating Curve Lab**

**Data**

 * There were 2 points where the temperatures leveled off
 * Overall, the temperature increased as time increased

Observations:

 * liquid started to boil
 * condensation occurred in the test tube
 * bubbling occurred in the test tube
 * all of the test tubes collected different amounts of the substances

Background Information:

 * The lab will be as long a the Heating Curve Lab
 * All the test tubes ( A, B, and C) will collect liquids

Inferences:
The three test tubes will have different amounts of liquid collected because of the time difference when each tube was switched.

Test Performed:
Fraction Distillation lab

Data:

 * Test Tube A:** collected the least amount liquid
 * Test Tube B:** collected the most amount of liquid
 * Test Tube C**: collected some what o an amount of liquid

Conclusions:
The liquids will tell us who did the crime.

=Day 5:=

Observations:
If the wooden splint lights on fire instantly, the substance is flammable

Background Information:
When we heated the mystery liquids in the fraction distillation lab, we then had fractions The data will be false if the flame is held on the wooden splint for too long

Infrences:
All fractions will have a different outcome when the test is performed. I think substance B will be flammable since that fraction had the most liquid.

Test Performed:

 * Flammability Test
 * Density Test

Data:

 * Fraction || Flammability Test || Density ||
 * A || yes || 0.77 ||
 * B || no || o.86 ||
 * C || no || 0.86 ||

Conclusion:
Fraction A was the only fraction that had a different density and was the only fraction that was flammable. Fractions B and C were not flammable and had the same density.

=Who Did It?= The criminal who kidnapped the penguin was Mrs. Cravner. All the other suspects did not have a matching pen to both of the ransom notes left behind, except for Mrs. Cravner's second pen we found. Other proof that Mrs. Cravner did the crime was she used actual chromoptography paper to write the ransom not which gave a big hint she "done it". The other teachers did seem more clueless about the whole situation where Mrs. Cravner did seem a little more relaxed with the news. The notes and clues left behind all lead up to Mrs. Cravner because she had no posters or any sort of evidence in her room.
