Lab: Crystalization of Milk

1. Put the milk into the plastic bag with some of the air but not too much.
2. Put ice and salt in to the basket.
3. Shake the ice until the milk has been freeze.

The milk is freeze as an ice cream.

1) Why do we add salt to the ice?
Salt make the milk freeze faster.2) Why do we add the cookies and other things, only after the milk has frozen slightly?
If we add them at first, the milk gonna be unfreeze. But if we add when the milk already frozen all of it, them gonna be unmixed.3) What are two factors that affect the freezing you think?
Ice and salt.4) Why do you need a bit of air in the bag?
If you have no air in the bag, the big gonna be freeze.

Impact of society on environment
               People use a lot of environment but people don't take care them. People use them more than they have, make pollution that disturbs the growth of living thing and destroy some space to make the factory or store.

               For now, the environment is hard to find.

Coal Pollution
               Coal contains sulfur and other elements, including dangerous metals such as mercury, lead, and arsenic, that escape into the air when coal is burned. Burning coal also produces particulates that increase air pollution and health dangers. Burning coal emits large amounts of carbon dioxide into the atmosphere. Air pollution from coal-fired power plants includes sulfur dioxide, nitrogen oxides, particulate matter (PM), and heavy metals, leading to smog, acid rain, toxins in the environment, and numerous respiratory, cardiovascular, and cerebrovascular effects.

This year is my 1st year at Panyarat High School. I think I don't have anything special in this class but I think I do worse in this class. I like the fish and shrimp activity the most. Next year I want to get the better score in Science.
