In-Class Response

In class lately we have been studying wind. We did an experiment with kites and how they flew. The kites didn't fly in the area we were at. I wondered why the kites didn't fly in the open field where as they flew at the beach. I came to a conclusion that there wasn't enough hot and cold air mixed together to create the wind our kites needed to fly. It also didn't help that our kites were heavier than the wind. When the cool air from the ocean and the warm air from the beach collide they create the wind that our kites need to be able to fly. This information can help me in the future if i want to plan a trip to the beach and i would like to fly kites, or do some other activity that involves the wind. If i know where is the best place, it could help save a lot of time.

Social Studies Advancement In Technology

One of the greatest inventions with the most impact on society made from newer technology was the hand held cell phone. Anywhere you turn, someone has a cell phone. This has changed society because it has made everything that has to do with communication a whole lot easier for everyone! You can call pretty much anyone you want to, and it doesn't take to long like the telegraph or letters do. Also, this something that you can take from your house, unlike a regular house phone. The cell phone has made life just an all around easier thing.

Did you know that the influence of what course children take in high school may come from what success their friends have? Lately, universities have been studying the topic of friendship and how it relates to academics. One friends success can actually motivate the child to do as good or even better than their peer. Studies have also shown that even though girls have to take the same amount of mathematics courses as boys do, they are more prone to trying to do what their friends do. Friends can challenge their peers without even realizing they're doing it.

Has anyone wondered why male children are particularly more interested in math than the female child? Recent studies have shown that children's fathers have been playing a big role in their kids interests in education. When the father has a son, he typically stereotypes between the son and daughter, and pays more attention to the son. Parents will more often buy more math related toys for male children then they would for female children, which influences their learning habits. This has shown a dramatic change in the way females and males learn today. The University of Michigan has been doing studies on this topic finding that more math products have been bought for the male gender.

Recently, a group of people have been studying lines for climbing trails. These people from the University of Washington have discovered when climbing a mountain, zig-zagged trails are more efficient than straight trails. Their reasoning was that if you "traverse" the mountain, you become less tired, and you have a better shot at making it up the full way, even though it's longer. They also say that if you attack the mountain with a straight trail, for it to be easy you'd have to find the exact angle to make it easier on you, and that could take a really long time.

Popping Lab

Lately in school we've been doing a lot of experiments in science. The most creative experiment we've done is our most current one, the Popping Fun Lab. In this lab, you had to shoot a cork at a window from the opposite side of the classroom. In order to do this, you had to combine two substances [baking soda and vinegar] to make carbon dioxide. The who chemicals reacted pretty quickly, so you had to put the cork on pretty quick.
After many times of trying to hit the window, we successfully hit the window three times consecutively. Not every group accomplished this task, but we were one of the lucky few who did.
Doing this lab made me realize, science isn't easy. You have to retry things to make them turn out the way you want them to. This also relates to how life in general works. If you don't accomplish a goal in life, try again until you acclmplish that goal. Like the experiment, if you dont persevere, you'll never get to where you want to go in life.

Monkey's Working Wonders.

Recently, scientists have been studying the way the brain works. They have been testing on monkeys to see how their brains work, to compare them to ours. This time, they put one specific monkey on a treadmill every day to see what her reaction was. As suspected, she walked for 10 minutes each day. Soon after, they placed electrodes in her brain to record her brain activity. After that they built a robot and connected the electrodes in the live monkey's brain to the robotic one. Then scientists observed as the two walked in unison. Scientists were shocked. The brain activity from the live monkey had transferred to the robotic one's. Soon enough, the real monkey stopped walking, but the robotic one continued to move.

As it turns out, the real monkey was still thinking of walking which is why the robot monkey still was in motion. From this scientists discovered that if you place electrosdes in paralyzed humans brains, all they have to do is think about moving, and they will be able to move the parts of their bodies that are paralyzed! This could lead into more great discoveries, all from one source. A monkey.
