=Day 1 Report:= =Observations= A note has been found with a ransom note. It could be Mrs. Laguna, Mrs. Cravener, Mr. Bile, Mr. Hood, or Mrs. Panny. paper chromatography can be used to determine which of the pens collected from each teacher wrote the ransom note.

Background Information
The penguin from Mrs. Laguna's room was stolen and there was a ransom note left. it says "if you ever want to see the precious penguin again- i want the roll of tickets"

Inferences or Hypothesis
Mrs. Laguna did it so we could learn how to list data like a scientist

Tests Performed
No tests were performed on day 1

Data
Got pens from teachers. evidence was found in Mr. Hood's room.

Conclusions
=__CSI Milford__= =Day 2 Report:= =Observations= The chromatography test turns the ink into the colors that formed the color for instance very dark purple could actually be in a black ink marker.

Background Information
The penguin from Mrs. Laguna's room was stolen and there was a ransom note left. It says "if you ever want to see the precious penguin again- i want the roll of tickets". We are performing a chromatography test to see which marker given matches the ink on the paper.

Inferences or Hypothesis
The test will not be conclusive. we did not gather the right pen or marker.

Tests Performed
We performed a chromatography test to see which pen or marker matches the one that wrote on the paper.

Data
We have the chromatography of all the pens and markers gathered

=__CSI Milford__= =Day 3 Report:= =Observations= The penguin has a black spot on him.

Background Information
The penguin was found in the hallway. he has a big black spot on him. there was a flask of liquid found next to the penguin.

Inferences or Hypothesis
I still believe it was Mrs. Laguna who killed the penguin

Tests Performed
We tested the density of the liquid found next to the penguin

Data
empty beaker= 18.5g beaker with liquid=27.9g liquid=9.4 liquid density=.94

=Day 4 Report:= =Observations= The penguin has a black spot on him.

Background Information
The penguin was found in the hallway. He has a big black spot on him. There was a flask of liquid found next to the penguin.

Inferences or Hypothesis
I still believe it was Mrs. Laguna who took then penguin.

Tests Performed
We finished testing the density of the liquid found next to the penguin. We performed a heating curve test of the liquid found enxt to the penguin.

Data
Heating Curve temperature recorded at 30 second intervals (degreed Celsius) 25 30 40 48 58 73 78 80 81 81 82 83 85 88 88 89 91 93 95 95 96 98 98 98 98 98

__CSI Milford__ =Day 5 Report:= =Observations= The chemical in the flask is a solution. One substance that could be in the flask is ethanol.

Background Information
We found the penguin in the hallway with a flask of liquid next to it. We are testing to see if ethanol is one of the substances in the flask. A chromatography test done on a pen from Mrs. Cravener 's room matches the chromatography test of the ransom note. we have also found paper in her room that matches the paper the ransom note was written on.

Inferences or Hypothesis
I believe water and ethanol makes up the solution. I believe it may have been Mrs. Cravener that killed the penguin.

Tests Performed
We performed a fraction distillation test.

Data
Only the first test tube contained a flammable substance.

=Who done-it= All signs point to Mrs. Cravener being the culprit. Her pen chromatography test matches that of the ransom note. Her paper matches the paper the note was written on. I believe Mrs. Cravener is guilty and tried to kill the penguin. There is no other teacher that have the clues point to them. Mrs. Cravener is the only teacher it could be. After days of testing, doing chromatography tests, fractional distillation tests, heating curve tests, we finally have evidence that Mrs. Cravener has to be the one that did this to the penguin.
