=Day 1 Report:=

Observations
someone took the penguin and left an ominous note in black ink asking for a ransom Mr.Hood and Mr. Bile are part of an anti penguin association and we have black pens from all our suspects. Mrs. Cravner is acting like she does not know what happened to the penguin but i think she might be the culprit.

Background Information
its a technique for separating and identifying mixtures that are colored and can be used in secondary and primary uses of ink http://en.wikipedia.org/wiki/Paper_chromatography __Mixture__- A substances mad by mixing other substances together __Solution__- A liquid mixture in which the solute is uniformly distributed within the solvent __Paper chromatography__- is an analytically method technique used to for separating and and identifying mixtures that are or can be colored especially pigments and can be used with secondary and primary sources of ink __Fractional distillation__-separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractional column

Inferences or Hypothesis
I think that it might be Mr. Lancos who stole the penguin

Tests Performed
we went to all the culprits rooms and got pens from them

Data
we got 7 pens from 7 different people who we think might be a culprit

Conclusions
we don't know who wrote the note but we are guessing suspects

=Day 2 Report:=

Observations
When we dip the paper into the alcohol and it reaches the ink it spreads it apart and the ink either turns a blueish purple even know the original color was black.

Background Information
we have many suspects and we are testing their pens using paper chromotography and it spreads the ink apart to see the diffrent colors.

Inferences or Hypothesis
I think it was Mrs. Cravener who wrote the note because she was very clueless

Tests Performed
we are using paper chromotalogy to find out who wrote the note we are testing the ink

Data
all the pens are leaking and the pens are showing many different colors such as brown,purple, green, and blue

Conclusions
we tested all the pens but not the note yet its looking pretty good =__CSI Milford__=

=Day 3 Report:=

Observations
-Most of the paper appears to look the same some are purple and black like Mrs. Craveners -Today we came across a dead penguin on the ground we checked the pulse but it was dead we don't know who did it but the girls gym teacher might have some answers. All that was near the dead penguin was a cup and a flask with unidentified liquid inside it.

Background Information
- dead penguin found do not know who did it

Inferences or Hypothesis
that the density of the liquid will help us determined the type of the liquid used to take out the penguin

Tests Performed
Density test mass of empty graduated cylinder- 17.5 cylinder and liquid together- 35.1 mass of liquid is 17.6 D=M/V density- 0.88 g/mL

Data
total- 0.88 g/mL

Conclusions
we got all the data for the liquid but never actually found out what the liquid was we might need to run some more test on the unknown liquid

=__CSI Milford__=

=Day 4 Report:=

Observations
a big heating curve occurred and we are one step closer to finding out the liquid

Background Information
we are testing the mystery liquid mrs. Cravener has the same kind of paper of that was used to right the ransome note but diffrent type of hand writing

Inferences or Hypothesis
that the heating curve will help us understand who wrote the note

Tests Performed
Heating curve

Conclusions
In conclusion we found out the Mrs. Cravner was the one who did it and Mrs. Laguna called the cops on her and everyone stood in the hallway watching Mrs. Cravener be dragged away and before she left she looked at Mrs. Laguna and said "this is all your fault you set me up" and that was the last we saw of her.
