During winter break, my mom and I went to Liberty Science Center and watched the show. My mom and I volunteered to be placed in a Faraday cage that blocks electromagnetic fields. The Faraday cage was put between the two the lightning rods which were emitting lightning. The Faraday cage prevented the lightning from electrocuting us. We felt very safe in the cage. It was an fantastic experience to watch the lightning closely. Oh, forgot to introduce Nikola Tesla, who invented this marvelous lightning storm. He had the idea for Smartphone technology in 1901. He designed the modern alternating current electric supply system to transfer electricity.

Wow! What a wonderful time I had at Liberty Science Center. I grouped up with 2 of my friends and visited many exhibits. We first went to the touch tunnel, but they didn't want to go, so I went with other girls and boys in my class. After that I found my 2 group members and did rock climbing. One of my group members completed the rock climbing, but I tried and tried and had no luck. Then we went to see the animals. I showed my friends a parrot named Mickey. Then we went to see turtles. They were adorable. A man was trying to clean something in there. He left the door open and one turtle was trying to get out. Then we had lunch and chatted. After that we went to the skyscraper and the gift shop. We also went to the PixelPalooza. Here is a picture of my friends and I.
Science! S-C-E-I-N-C-E! Science! Did you just say science? If you had asked me about science in 6th grade, you'd better run because I would have given an earful as to how I disliked science. I dreaded science quizes in 6th grade. I almost failed. Oh! wait!, I actually failed in first quarterly. Well, somehow I managed to get good grades later on. Honestly speaking, I didn't learn anything as I didn't understand most of the stuff. My mother tells me that I had hard time in science because we did not do experiments. If I remember correctly, we did only two experiments in the entire year.
Ever since I had Mr. Sinprasith as my 7th grade AEP science teacher I started liking it. Oh! I might as well say that I started loving it. He taught us moon phases and ascientific method. I never could identify independent and dependent variables in 6th grade, but after Mr. S taught us, I can identify them most of the time. He doesn't just give us homework without teaching the topic. He teaches the topics in a fun way and makes sure that everyone in the class understands the basic concepts. He is very cool and we do many experiments. Wow! I learnt all the moon phases and everyday when I look outside i can tell which phase it is.
There are 8 phases of the moon. The first phase is a New Moon. The second phase is Waxing Cresent. The third phase is First Quarter. The fourth phase is the Waxing Gibbous.The fifth phase is Full Moon. The sixth phase is the Waning Gibbous. The seventh phase is Third Quarter. The eight phase(last phase) is Waning Cresent. The first phase is a New Moon. The first phase is a New Moon. The first phase is a New Moon. The first phase is a New Moon. The first phase is a New Moon. The first phase is a New Moon. While on November 26, 2016 it was a waning crescent. I can't wait till November 29, 2016 because it will be a micro moon. A micro moon only occurs on some full moons or new moons and is 14% smaller than a Super moon. Did you know that many fish are dying because of the waters in the ponds, lakes, and oceans are being polluted with anti-bacterial dish soap, shower gels, and detergent? I heard that the chemicals in dish soap, detergent, and shower gels wash into rivers, streams, and oceans and causing a major disaster to the environment. Also, these are making bacteria resistant to antibiotics. Of this continues, none of the antibiotics will cure our diseases. How do we stop polluting the waters? One way not to take showers? No, no ! certainly a bad idea}. If we didn't take showers we would be producing a stench that our principal, Ms. V, would suspend us. Okay, I have a better idea. Let us use shower gels and dish soaps that contain natural substances which are environmentally friendly. In my science report, I have presented a simple germination experiment using mung beans that proves that dish soap is not environmentally friendly. Also, I have shown that natural substances such as, turmeric and red chili powder are safe for the environment. You must be wondering why I used chilli powder and turmeric in my experiment My grandfather uses turneric to bathe and he claims that it is antibacterial. Also I wanted to make spicy mung been sprouts using chili poweder in the water used for germination. Therefore, I also conducted the germination experiment using chili and turmeric in water to prove that both turmeric and chili powder do not prevent mung beans from germinating as they are natural substances.
Adding dish soap to water prevented germination of mung beans into tiny plants, thus supporting my claim that dish soap prevents germination of mung beans. Dish soap may have affected the chemical activity in hypocotyl and radicle of the seed, thereby affecting the germination of the mung beans. My two other claims, adding turmeric or chili powder to water would not prevent the germination of the mung beans, were also supported. Both chili powder and turmeric are natural compounds so these did not affect the growth of the mung beans. I noticed one interesting thing; the mung beans in the water containing chili powder had many roots. The chili powder in the water may have increased the chemical activity in radicle in the seed which then grew into many roots. From my experiment, I have proved that dish soap contaminates the water and soil and may prevent the growth of the plants. So we should use soaps, detergents, and shower gels made of natural ingredients that do not pollute water and soil so the fish and plants are safe. Hey have you gone to the Sun? No! Would you like to go and have a tour at the sun. Yes! Well, what are we waiting for? Lets go! All aboard ladies and gentlemen. I am warning you that i will be asking all of you what you have learnt during or after the tour. First Question: Is the Sun solid? No! [ding ding ding] Yes, the Sun is not solid it is a big ball of gas held together by gravity. You see there a dark patches on the sin. Second Question: Do you know what those dark patches are and do they move? Those are CMEs! They do not move! [wrong wrong wrong] Nope those aren't CMEs, those are suspots that move across the sun a the sun rotates. Third question: Does anybody know what are those things popping out of the Corona? Solar Flares! [wrong] Not really they are Prominenes. Prominences are huge loops of gas that occur near Solar Flares. See the other one. Those are Solar flares. Solar Flares are eruptions of gas from the Sun's surface that occurs when the loops in sunspot rgions suddenly connect. Come on everybody get into the sun machine. This machine will take us to each layer of the sun including the core. Oh, forgot to tell you that the corona can extend millions of kilometers into space. Cool, right? Sun is our closest star. There are many other stars. Fourth Question: How do stars shine? Give up? A star is a big ball of hot gas held together by gravity. Because of the high temperature atoms move quicly. Suddenly the nuclei joins to form a large nucleus. All of the energy radiates out into space from the core and that is how the star shines. Fifth Question: WHat is Nuclear Fusion? No! Nobody knows? Well, then listen very carefully. Nuclear fusion is the process in which atoms move quickly in a core of a star and then the nuclei combine to form a large nucleus. All of the energy is released. That happens in the core of the Sun. There are 3 interior layers and 3 outer layers. The outer layers are Photoshphere, Chromosphere, and then the Corona. The Chromosphere is the middle layer of the sun's atmosphere. The Photosphere is the inner layer of the sun's atmosphere. The 3 interior layers are the Core, Radiation Zone, and then the Convection Zone. I already told you what happened in the core. The Radiation Zone is a region of very tightly packed gas where energy moves mainly in the form of electromagnetic radiation. The Convection Zone is the outermost layer of the sun's interior. There is also a diagram called the Hertzsprung- Russel Diagram(H-R Diagram) that plots luminosity v. temperature of stars. The y-axis of the H-R Diagram displays increasing luminosity. The x-axis of the H-R Diagram displays decreasing temperature. Now for the test! |
