=Day 1 Report:=

Observations
The penguin is missing each teacher had a felt pen/marker many people we looked for had a black pen/marker

Background Information
technique for separating and identifying mixtures that are or can be colored http://homepages.ius.edu/DSPURLOC/c121/week9.htm

Inferences or Hypothesis
My inferences are that Mr.Hood took the penguin because he had a penguin on his computer with a cross over it. He also had a black marker on his desk like he was suspicious.

Tests Performed
Gathered pens

Data
all of the pens that we gathered together Mr.Hood had a picture with a penguin crossed off on it and Mr.Beil had a poster with the crossed off penguin on it

Pictures


Conclusions
We dont know who took the penguin and or who had the evidence. I think Mrs.Cravener has nothing to do with it because she acted totally clueless when we asked for a pen.

=Day 2 Report:=

Observations
Mrs.Kershman has only one color coming off of her pen and Mrs.Craveners pen is responding differently hers is starting to change to a blueish color and spread through the paper. Some of the pens responded to the alcohol differently then other. As in the changed faster or slower, different colors and ect.

Background Information
everyone has different pens and they all came out different results from the test

Tests Performed
Paper Chromatography
 * Mrs.Kershman isnt changing color
 * Mrs.Cravener is changing to a blueish color
 * Mrs.Rhodes is changing to a red and blue separating
 * Mrs.Laguna isnt changing
 * Mr.Hood Changing to a blue color
 * Mr.lancos starting to change to blue but isnt changing fast as most of the others. Changed to purple and blue.

Data
mass with out liquid: 17.3 mass with liquid: 30.4 density: 0.56

Conclusions
The penguin is still missing and not to be found or who took it. We took the test and now we need a sample of the note that they wrote and we will find out which pen matches with note. =Day 3 Report:=

Observations
A penguin is still, in hall way with a unknown liquid next to it.

Background Information
There is a unknown liquid next to the penguin and is going to be tested

Inferences or Hypothesis
The unknown liquid might be something that would "kill" the penguin The Heating curve increased and then stayed and raised only by one and stayed the same

Tests Performed
Density

Conclusion
The Heating curve increased and then stayed and raised only by one =Day 3 Report:=

Observations
There is a note from mrs.cravener and the paper matched the note about the penguin.

Background Information
The penguin was found! But laying next to a unknown substance

Inferences or Hypothesis
When the heating curve got as high as 78 and stayed like that for a longer time and every other time was because it was at the

Conclusion
Since Mrs.Cravener is not responding to the penguin being gone like everyone else is im starting to thing that she is going to have something to do with the penguin
