Bohol Earthquake

It was really hard to accept this, I don't even know that this would be happening to our neighbor country. When I saw on TV ,it was really shocking me . I need a million time to believe it. I saw many corpses out there ,it was like the sea of corpses where the water is blood. I heard people were crying ,they were trying to find their families among the ruins ,which hard to find it. Scream and shouts were like the sound background of this disaster. I can't believe it , I lost everything that I have , I forgot to taste what's happiness.
They were trying to get out from ruins , the sounds was thunderous when the buildings crashed to their little body. As you know that without  telling you,you can directly imagine how the condition is. A small body asked for help ,but no one couldn't  help ,they were busy with their safety ,they were trying to survive but they couldn't escape it. Can you imagine a giant rubble crashed them , an asphalt road  split so that they fit into it. Oh my goodness ,the only thing that we can do for them is pray hard for them ,pray for our neighbor country . And hopefully this would be the last disaster that came to us. Stay strong my brothers and sisters in Philippines out there , may God bless you on what has happened to you.

- Ethanol                                                                                                

- Sticky rice (Lontong)                                                                            

- Brownies                                                                                              

- Rice                                                                                                      

- Coconut oil                                                                                           

- Alcohol                                                                                                 

- Bread

Equipments :
 - Test tube
- Filter funnel
- Mortar & Pestle

- Stiring rod
- Test tube rack
- Filter paper

Preparation of a solid sample :

1. Completely crushes adequate amount of food with a clean and dry mortar and pestle.

2. Transfer an adequate amount of crushed food sample to a clean test tube

3. Adds 2cm ethanol above the food sample

4. Shakes the test tube thoroughly and safely .

5. Allows the solid to settle for about 3 min

6. Decants the ethanol carefully into a clean,dry test tube without transference of food particles.

7. Adds 2cm of de-ionized water to the test tube

8. Compares each result with the negative control

9. Compares the heights of the emulsion layer of all the samples

Process

• Add the food sample to 2 cm3 of ethanol, shake well.
• Allow to settle in a test tube rack for 2 minutes for food to dissolve in ethanol.
• Empty any clear liquid into a test tube containing 2 cm3 of distilled H2O.
• A MILKY-WHITE EMULSION is a positive result: lipid is present.
• If the mixture remains clear, there are no fats present in the sample

Substance tested	Presence of spot	Lipids presence ?
Brownies	Yes	Yes
Rice

Cooking oil	yes	Yes
White bread	Yes
