=Day 1 Report:=

Observations

 * Penguin is missing - Cannot be found
 * Ransom note found - threatening the wooden penguins life for a roll of #|tickets

Background Information

 * Paper #|Chromatography - Can be used for secondary and primary #|colors in ink experiments - identifying
 * Mr Beil has a picture of a penguin crossed out and hanging up in his room. "Founded the Anti-Penguin League"
 * Mr Hood is standing in front of a picture on the #|smart board with a colored picture crossing out a penguin- thumbs down

Inferences or Hypothesis

 * All the markers will show some color

Tests Performed

 * Chromatograpgy paper test - Everyone's marker was tested - 7 tests in all
 * 7 tests were performed and the gathered information revealed some color and "smears" except Mrs. Kirschman's marker

Data

 * **Tests;**
 * Kirschman - the dot didn't smear at all
 * Rhodes - The black dot smeared into a green/purplish color
 * Hood - Smeared into black/grey blue, and green
 * Beil - Black dot - dark greenish/yellow, blue, dark blue
 * Lancos - Purplish/dark green
 * Laguna - Black dot - smeared into grey/purple, blue at the edge
 * Cravener - Yellow, orange, blue

Conclusions

 * Using the paper tests to determine whose behind writing the ransom note

**Observations**

 * Chemical smells like #|nail polish remover
 * Penguin was found with a suspicious clear liquid in a flask
 * Found a plastic drinking cup next to flask - near penguins body
 * Empty Cylinder; 40.3 grams
 * With liquid - 49. 3 grams
 * Liquid only; 9 grams
 * M/V = 10/9 grams

**Background Information**

 * The substances in nail polish remover can be dangerous to #|health; irritant to eyes and harmful if inhaled in large amounts

Inferences or Hypothesis

 * The unknown suspicious liquid could be deadly

Tests Performed

 * Density tests of the empty cylinder, cylinder filled, and ransom note was tested

**Data**
Density Test;
 * Empty Graduated Cylinder - 40.3 grams
 * 10 mL Graduated Cylinder - 49.3 grams(estimated the liquid to weigh 9 grams)
 * Ransom note was tested - Dark and light blues, pink, purple, brownish gold

Conclusions

 * Whoever has had the penguin and returned him back to the main office (where he was found) has obviously used some sort of harmful chemical on him, and has perhaps made him drink it to do some kind of intentional damage.

Observations

 * Boiling
 * Condensation
 * Foggy
 * Temperature increasing
 * Starting to slow at rate - Around 4 minutes
 * Starts to increase a little bit - After 4 minutes - increasing by 1 or 2
 * Around 10.5-15 minutes - Stops/stays around 98 and 99

Background Information

 * Temperature on the unknown liquid should increase

Inferences or Hypothesis

 * It burns easily

Tests Performed

 * Heating Curve Lab

Conclusions

 * This unknown object is flammable - heats up quicker

Observations

 * Increased - then started staying the same around 10.5-15 minutes

Background Information

 * Heating the mysterious liquid

Tests Performed

 * Fractional Distillation - using three test tubes labeled A, B, C - set up exactly like heating curve lab - did exact same procedure except changed it everytime it plateaued

Data

 * Test Tube A - Stayed at 78 then switched to B at 81 degrees
 * Test Tube B - Stayed until 98-99 degrees then switched to C
 * Test Tube C - Will not go any higher - stopped increasing - leveled out

Conclusion;

 * Three different substances turned three different colors

Observations

 * Two liquids are a shade of yellow, one clear

Background Information

 * Heating the mysterious liquid with three other substances to help identify what the liquid is
 * Three different types of liquid substances

Inferences or Hypothesis

 * One will at least give away what the substance really is

Test Performed; Flammability
Density;
 * Dipped a wood split into one of the three substances(liquids)
 * Lit a match - watched to see if a flame appeared(Did same thing for each of the liquids)
 * Measured how much an empty graduated cylinder weighed - poured 10 mL of liquid into graduated cylinder
 * Procedure for all three liquids - A(.73 grams) B(.89 grams) C(.97)
 * Subtracted the weight of the graduated cylinder with the liquid - divided to get 10 as density

Data

 * A - Flammable
 * B - Flammable
 * C - Non-flammable

Conclusions

 * Two of the three liquids are flammable - densities are similar

Who Took The Penguin

 * We believe that Mrs. Cravener took the penguin because most of the evidence belongs or leads to her
