International News and Class Response

Recently, Erno Rubik created the next generation of the classic Rubik's Cube. This New Rubik's Cube is no longer a cube but a sphere. For the past couple of years, Erno has made many different lessons and mind teasing puzzles. This new sphere has one outer sphere as well as two internal spheres that are held together on a rotating axis. Inside the internal spheres are six different colored balls to correspond with domes that pop out of the outer sphere. With the same matching idea as the classic Rubik Cube, you have to match the colors of the balls inside the domes popping out of the outer sphere. I think this is a unique twist on the puzzle everyone loves. I think this is important news because it is a new generation of a classic puzzle. The Rubik 360 is a great new take on the mind teaser and is really cool! It is cool because not only does it have the mind puzzles but it also is a really different, fun game. The article also said that this new and advanced Rubik's Cube has a more science and gravitational lesson. When trying to solve this puzzle, it is more kinetic and more physical. During science class we recently made roller coasters. We were taught about potential and kinetic energy as well as gravity.
Kinetic energy is the energy of motion. Recently, I learned that there are three types of kinetic energy. They are vibrational, rotational, and translational. Kinetic energy is used on a roller coaster when it is at the highest hill of a drop because it is moving the fastest. Gravity is used going over the hill. When the coaster starts to go over the hill it is using energy, then as it starts to descend, gravity pushes down on the cart and allows it to go over and complete its journey.

Stem Cell Funding in 2009

Since we have a new President, many things are changing. A new stimulus package is being reviewed by the entire administration. They are looking for ways to help the economy and the health care industry. One topic that has seemed to stick out is Stem Cell Research. Stem Cell Research has been hard to get during the Bush administration but many supporters have hope for Obama's plans. Stem Cell Research could possibly help restore the blood cells and change them into any of the 220 varieties of cells. This could eventually help cure diseases, such as, heart disease, diabetes, Alzheimer's, and Parkinson's, just to name a few. I believe Stem Cell Research is a good thing. It may take a while to get the tests perfect but as the article says, many doctors are confident in the results of the tests.

State News

For the past couple of years Gov. Jon Corzine raised the standards for state wide tests and curriculum's. Recently, the results of those tests and the report cards of many schools were unbelievable. Teachers, parents, students, and critics were shocked to see that the passing percentages abated. The shocking news was not only in our county but state-wide throughout New Jersey. Although the parents and critics were shocked, many state officials were not. They were aware that the demand for high achievement was high, but they changed it so we could be ready for what awaits us in college. Lately, I have noticed a change in our classes curriculum. For social studies for instance, we started a interactive notebook and a text book that we carry with us. I like this better than last year because last year I found myself confused and having to search my folder for papers we went over in class. I believe the new curriculum is harder but it hopefully will prepare me for next year.

The 44th President of The United States of America: Barack Obama

Just yesterday, Barack Obama was sworn in as the 44th President of The United States of America. This was a historic moment because Barack Obama is the first African-American president. Luckily, I was able to watch the Inauguration at school and see President Obama get sworn in. As I was researching the topic, I came upon two articles that explained the Inauguration in a great way.

The first article I read was written by the New York Times. It talked about the millions of people who joined the President and his family from the capitol to the National Mall and beyond. His many supporters started chants saying, "Obama! Obama! Obama!" The article also discussed how Barack and Michelle Obama had to attend 10 Inaugural Balls that evening. It was already a long day and President Obama had to continue it to the wee hours in the morning. I believe that Barack Obama is a great man. He is respectful, intelligent, and funny, some of the many things we need in a president. When interviewed at one of the Inaugural Balls he was quoted for saying, “Hit it, band!” That shows that he has a sense of humor. You can find the article at http://www.nytimes.com/2009/01/21/us/politics/21obama.html?_r=1&ref=us.

The second article I read was about the many people who traveled hundreds of miles to witness history. Avil Lawrence and Lou Johnson went with their children to witness the amazing moment. Lou Johnson's son is 40 and said "'To be honest Dad I never thought I'd see it.' So, here we are able to see it together." Avil Lawrence was apart of one of the first segregated classes in 1971 and was proud to witness Barack Obama become president. The article makes me understand how others feel about this moment in history. I think that it is a big step for all Americans to start new, especially at this time. The people who were apart of the celebration might not have been able to see the actual swearing in, but they were happy to be apart of the event. You can find this article at http://www.nola.com/inauguration/index.ssf/2009/01/streaming_north_witnesses_to_h.html.

Overall, I thought the Inauguration was a historical moment that will forever be remembered by our generation as well as the many generations after us. I am happy to say that I was watching and able to be alive for this amazing time.

A Twisterssssss's Spin

Recently, two meteorologists at the University of Oklahoma, Nathan Snook and Ming Xue, have ran a series of simulations to study how tornadoes get their spin. First of all, tornadoes are caused by hot, humid weather in a cold clouded area. The men tested many different types of precipitation to see what could help cause a tornado's spin. Including, small hailstones, large hailstones, small raindrops, large raindrops, small hailstones and raindrops, and large hailstones and raindrops. They concluded that the size of the precipitation is a part that makes the tornado spin. When there is a small droplet of water, it is easier to evaporate, causing the rain or hail to fall to the Earth. This is also because smaller amounts of precipitation cool the air, eliminating the hot, humid air that causes a tornado. Larger droplets resist evaporation and do not cool the air during the storm, creating low pressure and starting the sucking force in the air. This force spins the air and creates the spin of a tornado. I think this is a cool topic to learn about and study because you can always witness weather and its everywhere around you. It is also cool because I never knew that something actually caused the tornado to spin, I thought it was only because that was what a tornado was. This is just another step to finding ways to prevent the damage tornadoes around the world have put onto lives and many peoples homes.

Transverse and Longitudinal Waves

(a) is an example of a longitudinal wave and (b) is an example of a transverse wave.

This month during Science class we have been learning about transverse and longitudinal Waves. Transverse waves are waves that moves the medium at right angles to the direction in which the waves travel. Longitudinal waves are waves that moves the medium parallel to the direction in which the waves travel. Both of these waves have similar characteristics. They both have a crest, which is the high part of a wave, and a trough, which is the low part of a wave. The wave is measured by its amplitude, frequency, wavelength, and speed. In class we did many activities that correspond with waves. Such as using a slinky. When you push the slinky on one side, you can see the wave traveling through to the other side. When we were diagramming transverse waves we used a spring rope. With a partner holding the other side, we moved our hand up and down. Starting slowly, we noticed that it looked like a wave in the ocean. As we speed up, the waves became smaller and they would pass a point more frequently. I learned a lot about waves in the past weeks but when I searched transverse and longitudinal waves, I learned something new. I learned that water waves travel in a clockwise cycle. I also learned about a Rayleigh surface wave. These water waves move in a counter-clockwise cycle but deeper in the wave, it turns into a clockwise motion.
