Introduction:
Inside the school, Yew Chung, a twins was kidnapped, their parents were so afraid about this tragedy. Few days later, there is a note send from a "unknown" person to the parents of the twins. The notes said that the parents should give the person 20000 us dollars, if not, the twins will be killed. The suspect of this case is Mr. Matuk, Mrs Poon, Mr. Siu and Mrs Khadun. Mission Impossible: MY PARTNER AND I NEEDED TO FIND THE CRIMINAL IN A SHORT AMOUNT OF TIME, 30 MINUTES!
Objective:
To discover who wrote the ransom note through chromatography.
Hypothesis:
I think that Mr. Siu is the criminal because the pen's thickness looks like the the thickness of the pen in the ransom note.
Materials:
- 4 pens
- ransom note
- chromatography paper
- pencil
- ruler
- 250ml beaker
- 1% salt solution
Procedure:
1. Prepare all the materials
2. Put less than 1 cm of salt solution in the beaker, and dip the ransom note (note wrote on chromatography paper) into the water
3. after the water has soaked up, see the chromatogram and record down the results
4. wash the beaker and pour the salt solution again
5. use a pencil and a ruler to draw 1 cm width line on the chromatography paper
6. use the 4 pens to dot on to the line, should have distance away!
7. then dip the chromatography paper include the pen dots into the salt solution
8. wait the water to soak up and look at the chromatogram
9. Record down the results
P.S. Take a picture of the results!
Results:
Ransom note chromatogram colour: black, red and blue
Zebra (Mr. Matuk): green, dark blue and yellow
Pilot (Mrs Poon): green, black and purple
Taro (Mr. Siu): black, red and blue
Pentel or White board Marker (Ms Khadun): black (no change of colour)
The results proved that the criminal is unfortunately Mr. Siu!
Guide Questions:
1. Who is the kidnapper?
Mr. Siu is the kidnapper, because his pen matched the ransom note's.
2. How did you find out?
I find it out by using the method chromatography. The results also proved that Mr. Siu is the kidnapper.
PICTURES ARE DOWN AT THE BOTTOM!!!
Ending of the Story:
Mr. Siu is caught and is prisoned to jail, while the twins was found dead inside a broken house. The parents of the twins took a revenge, and kidnapped Mr. Siu from jail. A ransom note was sent to Mr. Siu's rich parents.

This is the picture of the ransom note chromatogram and the 4 pens chromatogram. Do you notice that which of the 4 matched the ransom note?

This is a very impressive photo! It is beautiful!!! Anyway, the results shown that the Taro, Mr Siu's pen have the same chromatogram of the ransom note's; both the chromatogram is also the colour, bleu, red and black!!!

Mission Impossible: This is the chromatogram of the ransom note. Mission Impossible became to Mission Possible and Success, the taro matches this chromatogram, the criminal or the kidnapper is the humble outside evil inside Mr. Siu!!!
