Whoosh! That's the sound a kite makes when its soring through the sky. Have you ever flew a kite on the beach and wondered how it flew. Well i have three interesting facts on why I believe kites fly. One interesting fact is that most kites are light in material, so that they will be able to sore really high in the sky. Also, the sea breeze gives the kite lots of wind to fly because the land is hot in the day time so the ocean with be giving lots of wind that will make the light objects fly like kites. Lastly, the shape of kites affect the way kites fly. For example, if a kite is a one dimensional shape it might fly better than a three dimensional kite because the one dimensional kite is very light and the wind could easily pick it up, but with a three dimensional kite the wind might get caught in the packets, and the will not get enough wind to make it fly. Two other interesting facts about kites are that they were invented back then by the Wright Brothers and in 230 B.C. they were kite flying festivals in Japan. In conclusion, kites are very unique and there are many ways that they fly.
Have you ever done or watched an experiment that you thought was the coolest thing ever? Well I have, for example when the a teacher came to our science class and showed us a little experiment on density. It was really interesting because to make one liquid denser than the other she just added salt. However, she also had many different colors of liquid so that you could see the change. For example, if the red liquid had no salt then it would float to the top, but when she split the the red water into two sections with board and put a blue food dye into one of the sections and added a ton of salt, then took the board out of the sections, you would see that the blue dye would sink to the bottom because it was denser than the red dye. Also, she did an experiment that involved a straw and the many difffernt colors of the rainbow . For instance, she took a straw and had many cups for different colors that were different desity's, then she dipped the straw into the least dense color and so on, until she got to the densest, and inside the straw was the rainbow. Density is the physical property of matter. Also, density can be decribed as how closely "packed" or "crowded" the material appears to be. In my opinion, density is very important in our lives, because if we didn't know about density we would not be able to understand why in the ocean the warm water floats to the top and why cold water floats to the bottom. In conclusion, density is very important and there are many important examples that can be used to teach someone.
In today's world the technology is outrageous, it is so advanced that some of the items, tools, and electronics we have today, did not excised thirty years ago. A perfect example would be the computer. The computer has made the biggest impact on society because without the computer I would not be able to write this blog, or type essay's or look up information I didn't know. Also, the invention of computers have allowed people to email each other and talk online. Additionally, with computers we can look up pictures on the Internet, search famous scientists, and find current events about the world. In conclusion, I feel that computers have greatly impacted our society, but it's only until a new scientist invents something even greater than the computer.
Did you know, if you worry about how you will perform on a math test, it may actually contribute to a lower test grade. The feelings of fear or dread, can sap the brain's limited amount of working capacity. You need that working capacity because it helps you complete difficult math problems. Mark Ashcraft, a psychologist, says that "math anxiety occupies a person's working memory." However, worrying about the math task can take up a large chunk of the person's working memory as well. Also, he said "While easy math tasks such as addition requires only a small fraction of a person's working memory, harder computations require much more." Stress about a test can even make the smartest math student choke. Everyone gets nervous or stressed out about a test, so I think that everyone should think positive and believe that they are going to get a 100 on that test.
Every student, has to take a math test while their in school. Recently, nine states have decided to make a common high school math test for the first time. The states include, Arkansas, Kentucky, Indiana, Maryland, Massachusetts, New Jersey, Ohio, Pennsylvania, and Rhode Island. All of those nine states are trying to figure out which students to give the test to, but they know that the test will probably go to the students who are taking Algebra II. Also, the states are thinking that they are going to consider making the test scores available to collage placement offices. Students usually take Algebra II after taking algebra and geometry. Research has shown that students who complete Algebra II, are more likely to earn a collage degree. By knowing that, more states are requiring their high school students to take Algebra II. However many people are disagreeing with the decision to have a few states have to same high school math test, they feel that the states are setting there standards too low. Also, many more students are able to achieve proficiency on the state tests than on national math tests. In my opinion, states should make there own tests that are different from other states, because when the actual tests cames around then that will judge how much that student really knows on that subject.
More than 40 years ago, the country was introduced to a "new" math. But, slowly this "new" math in schools has been replaced with an even "newer" math. In some schools this "newer" math is being used with an effort to spice up the learning. Many students love that "newer" math because they do not have to memorize different tables and formulas. However, some experts disagree with the "newer" math. For example, they feel like the "newer" math has too much color, and too many examples. Also, they feel like the teachers are leaving out important information that the students need to know. To add emphasis, they feel like the parents of the students should ask questions about the teaching methods, and talk with school officials about the test scores of the students. In my opinion, we should stick with the "new" math because if the students aren't learning the right material then, that student could have difficulty the state test. Also, people feel that this "newer" math is not helping the students learn the right essentials. In conclusion, if the "new" math has helped people learn math in the past, then why would we change that math in the future.
The topic that I have decided to blog about is the lab that we did in class that was called the popping lab. Three interesting facts about this topic was the when the group mixed baking soda and vinegar, the cork popped off the test tube and went some amount of meters. Second, depending on the amount of baking soda put into the lab determined how far the cork will fly. Third, this lab required the groups to really think about the quantity of the substances, because if the cork flew to the window three times then the group would get extra credit. In my opinion, this was great. However, there are a lot of class room labs on the Internet. For example, Google has a lot of great websites, that teach people how to do that lab at home. In conclusion, labs are the funnest things ever.
