Day 1 Report:

Observations

Our class room penguin was taken from mrs. lagunas room and left a ransom note for a roll of tickets or we will never see our penguin again

Background Information

http://en.wikipedia.org/wiki/Paper_chromatography

Inferences or Hypothesis

i think the person who did it was the one we dont expect to do it at all as in Mr. Pieffer did it because he knows when everyone is out of the room and when they come back into the room.

Tests Performed

investigation to all the suspects in the eight grade teachers

Data

Mrs.Laguna, Mrs.Cravner, and Mr.Biel, Mr.Lancause, Mrs. Kirstman, Mrs.Rhodes

Mr. Hood

Conclusions

in conclution mr. hood did say he always hated the penguin and that made him aa step farther than all the suspects and mr. hood and mr. biel both had picture of penguins with xs on them and made both of them a super suspect. but mr. pieffer knows were and when mrs. laguna will leave the room and how long she is away plus how and when mrs. laguna returns. therefor he can take the penguin and leave a note asking for tickets, cause he always has black pens and markers and is alway prepared.

Our class room penguin was taken from mrs. lagunas room and left a ransom note of a roll of tickets or we will never see our penguin again we are testing all the markers.

Background Information


Inferences or Hypothesis

i think mr. lancauses pen will be a pefect match to the reansom note pen

Tests Performed

We are doing chromotagraphy tests whit chromotograpphy paper to test the evidence for the correct pen use in the ransom note.

Data

Mrs.Cravener , did smear and change blue, Mrs. Kirstman is not changeing or smearing, Mr.Biiel did smear a little and changed color, and Mr. Lancause smeaered alot and is looking like a rainbow, Mrs.Laguna,is smearing, and Mrs. Rhodes is also smearing.

Conclusions

In conclusion I now think that Mrs.Kirsman had a pen collected and that pen did not change at all in the chromotography test but we yet still did not test the ransom not yet. So everyone has a good chance of being the culprit. At last we know who looked more clueless and that is usually the person who committed the crime
and see who done it.

Conclusions

I think the mystery liquid is just water and not a harmful liquid and who ever planted it that they would not have any sign of suffering or sickness.I we should have someone small and quiet in a box with holes in it and the person has a camera and take a picture of who walks up to the box and bingo we have the person red handed.We can ask the secretary for the security footage to see the culprit an even faster day.
