Heat Transfer_Popcorn Lab (10pts) [;

In my Red science class, I conducted a radiation popcorn experiment. What i had to do was microwave popcorn. I know what your probably thinking which is that this has nothing to do with science whatsoever and that this is just a lame excuse to satisfy my hunger in science class but your wrong! This lab showed radiation and how heat is transferred with molecules. Radiation is the process in which air is heated and this process is the only way that the heat is transferred to move around in areas of space. Radiation causes molecules from the popcorn to vibrate and it moves the heat in the kernels which causes the popcorn to pop. The moisture in the popcorn kernels extend when the moisture inside the kernels get hot enough which makes them build up pressure transform into popcorn. In order for this to happen, there has to be a certain amount of heat in order for the popcorn to pop. This is how your favorite movie snack that seems simple is made. This proves that even the simplest aspects of life can deal with science. Next time you should ponder the simplest things in life and then you can see the nothing is actually simple. ~Vikinggirl15<3>

Air Pressure_ Collapsing Can Lab (10pts) :D

In science class, we did a collapsing can lab which shows how air pressure has the power to crush a can so easy right before your eyes! When you heat the can half way filled with water, you cause the water to boil inside and turn into water vapor (which is a gas). Then this gas from the boiling water causes it to push all of the air out of the can. After putting the heated can filled with water vapor into a tub of ice cold water it will make the heated molecules cool instantly. When the can gets put into the water it makes the vapor condense and force all the air into the can to push all the air out. This makes the can get all scrunched up and close together in a flash. You may think this is magic but this is merely just science and the process of air pressure. :DD I recommend trying this at home because its easy to do and I enjoyed this experiment! ~Vikinggirl<3

The Greenhouse Effect_Respond (15pts) :)

The Greenhouse effect article I read made me change my opinion about how important this is to the Earth. A few important facts I learned were:
*The problems begin when human activities change the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature.
*Scientists agree that even the smallest increase in the global climate would lead to significant climate and weather changes, affecting cloud cover, precipitation, wind patterns, the frequency of storms, and the length of seasons.
*Many of the world’s endangered species would become extinct as rising temperatures changed their habitat.

This proves that WE are the ones who are causing the greenhouse effects that are occurring in the atmosphere. Therefore, we have to find a way to stop this before chaos breaks loose and the place that is now called Earth will turn into a disastrous place of havoc, destruction, and devastation! I was absolutely shocked when I read this article and now I just hope that the worse isn't going to happen and that Earth will still be able to sustain us and all the future generations that are yet to come. :0) ~Vikinggirl<3
