What is the myth?

If gum affects your brain which helps with the athletic abilities

Where did the myth come from?

This myth came from sports

Why does it matter that this myth exists? (Moral, ethical, social, environmental, political, cultural, OR economic issue?)

This myth has been found by sports players who started chewing gum and played better.

What is a better, current theory about the working of the brain?

Myth isn’t true because it is scientifically proven that chewing gum increases your concentration which increase your athletic abilities.

 

What does chewing gum do?

It keeps your mouth moving which makes your brain active. Also it improves heart rate, blood pressure, calms you down, and it draws blood to your brain. Gum chewing increases the level of activity in the frontal lobe of the brain, making the brain more alert and increasing cognitive functions. General levels of caution and arousal levels, which shows the degree of reaction and shortens the body’s response time. A quicker response time means quicker movement and action in the fast-movement muscles, giving players advantage on the field. Chewing gum gives athletes the ability to run slightly faster and jump slightly higher due to concentration. Chewing gum also decreases adrenaline, which reduces stress; factor that also affect performance.

 

Reflection on going around the world with a lot of option to choose

In this unit we have been studying about speed of objects moving. I noticed that there s a lot of ways to move around countries. Nowadays we can travel to other countries or in a country really fast because there are new technology that makes that possible. For example many of the developed countries has bullet trains which is fast enough that it takes you 1 and 20 minuets from tokyo to kyoto. Also not only that we can now fly with planes which can take us over the sea faster than using boats. I think it is really convenient that we have all these things that can help us move faster. Also the speed is getting faster and faster which can make our lives easier and more efficient to work.

Under Sea Resources

lanthanum

Chemical element with symbol of LA

neodymium

Neodymium is a chemical element with the symbol Nd and atomic number 60

yttrium

Yttrium is a chemical element with symbol Y and atomic number 39.

From long time ago people have knew that there were resources in the ocean but they didn’t have the definite facts to prove it. People thought that it provide a wealth of rare-metal. It would be molten to fluid with the heat and would be pumped out if possible. However Yasuhiro Kato and his colleague discovered that there are resources under pacific ocean and near hawaii. They’ve found concentrated area of where the resources were. For example there were lanthanum,  neodymium, yttrium. Right now, China is the biggest industrial country that has rare resources and they are making it more expensive so other countries have to pay more. Now more places over the word are mining for the rare resources for example California, Canada, and Australia. People say that mining the ocean floor will take a lot of money and skill. It would cost time too. Also other people say that it will create environmental problems that will make the earth more dirty. I think science of finding out where there are metal/ resources are used in this article. Also they’ve thought about how to drill it out. They calculated how much things it costs when drilling it out. If they can drill the metal out from the ocean floor it will change economic dramatically since they will get a lot of rare metal from the ocean. People who started to drill it out will get really rich. It is beneficial for human being because people would be able to get more rare metal that will create things that are very useful. However it will not be good for the environment because there are possibility that drilling can make the ocean polluted and kill fish and animals.
