There was an ISWEEP science fair held in Texas. There, I have presented a project that tested on miniature houses to see which plants does its function of cooling and heating the best. There were three different plants used in this experiment; Sedum, English Ivy and Winter Berry. These were all succulent plants meaning that they store massive amounts of water in themselves. Therefore, the water doesn’t evaporate which will not take heat away from the house. This keeps the house warm during the winter. Also, plants in general have roots that tie tightly with each other. These protection of soil will keep the house cool and prevent the sunlight from heating the roof too much.
 
 Planting these plants definitely have a massive effect in saving the costs of air conditioning and heating.The plant that was represented as most effective was Sedum because it was a succulent plant with more water storing capacity which means that it can store massive amounts of water in the roots compared to the other plants to even survive in the desert. 


The reason I started this experiment was because of the concern that our earth is going to get destroyed. Like in the movie 2012, a disaster due to Global Warming could kill all of the mankind and bring end to this world. Therefore, we all need to keep this in mind and come up with some other way that we could prevent Global Warming from proliferating. 



 Then, what is Global Warming and its effects? Why are people conducting these experiments and putting so much effort into it? Global Warming is a phenomenon that occurs when earth’s hemisphere is destroyed by the CO2 released by human constructed machinery including automobiles, refrigerators, heating devices and air conditioning. The sunlight shines strongly through these holes in the hemisphere and therefore causes earth to overheat. By Global Warming, glaciers in North and South Pole melt down and some countries like Maldives will drown due to excessive amounts of water melted from the glaciers. This might not seem very devastating to us who is not the natives living in Maldives but it definitely will affect most of us soon or later. 


Everyone as a citizen inside the earth has to gather strength and effort in order to prevent Global Warming from advancing any further. There has also been a research done by Michigan University if green roofs save excretion of CO2 by decreasing heating and air conditioning prior to the Science Fair research project. The result was that plants on top of the roofs do cool down the houses and warm the houses depending on the outside temperature. 

Other than these experiments, there are many more experiments being done to protect our earth and to save the human kind from becoming extinct over time. Everyone should take action in the way they can to save the earth even by walking instead of driving cars. These issues are the ones that bring everyone on the earth as one and we should all help prevent this cause. 

 Of course it is not very easy for the students themselves to do such experiments to save the earth. However, that is what ISWEEP is for! ISWEEP ables students to show what they have researched in front of the judges who are experts of those category. This competition is held every year in Texas and international students are also eligible to attend. You have to register the topic of your experiment in detail first and the organization informs you if you can come to the Texas competition or not. When you get qualified for the Texas competition, you go and you can earn medals at the same time show other scientists what experiments could be done. The website for this fabulous competition is http://www.isweeep.org. This is a wonderful way to contribute to the earth. Everyone should try submitting their work to this.
