Amazing story!!! please read this as well, it is where I got all my information

This is a very interesting article about the recently invented and discovered tape (20 by 20cm) can hold an entire man. It has the same elements of a geckos feet and is the first time we have ever been able to mimic it. The reason geckos and some other animals do walk on surfaces without being affected by gravity or things such as it is because they have thousands of tiny hairs called setae (pronounced see-tee). They cover their entire feet and legs. Eventually the hair is split into a thousand pieces and at the bottom of each one there are these sort of suction like cups called spatula that hold the gecko on the wall or ceiling or whatever they are on that gravity does not effect. If they want to let go and fall they just send their setae to another angel. The only problem about it is that it is very costly and will not be out into he market for purchases or use to any media or anything until they are able to reduce the price.

   I find this article very interesting. I find it simply ravishing and amazing that it is even possible for a 20cm x 20cm piece of tape can hold a full grown average height and weight man. Up until now this has never even entered my mind. I cant wait to and hope to see the day that it is released onto the market so i can try this miracle tape myself. I feel that this article shows how far science can go and that all the possibility are endless.

Mock Mission to Mars Article Summary and Reflection

Mock Mission to Mars is a Dogo News Article from here It was published on November 6th 2011
In this article they talk about how the European Space Agency (ESA) had six very brave astronauts  who agreed to do a pretend trip to mars They were sealed in a 1,000 square feet for five hundred and twenty days. They were all from different nations and the only form of contact that they had with the outside world was through via time-delayed e-mail or through the mission controllers. Because this was all they would have if they were really to go to mars. Just think of having to sort our how much food was allowed to be eaten and how much water was allowed to be used throughout the day. You had to think also for the water extra because there was a greenhouse for growing fruits and vegetables, so you would have to calculate how much water would be used for growing fruits and vegys and how much would have been used for daily consumption. Also becuase of this ti has allowed us to get many answers to mnay questiosn that we were not sure of for when in decades to come, we would actually travel to mars. For example, we did not know how people would act in a confined space for such a long time.

However, I do ask my self some questions. Could they leave when they wanted to, and could I ever do that?? I would think that is something dreadful happened, for a close member of the family or friend died, you could leave, or you just simply coukdnt bear not being with your familt any more, or you just wanted to leave, you could. Personally I do not think I could ever stand that. Being away from my family and friends for that long would be impossible. Also I was wondering if those astronauts knew each other and were friends, or they simply only met for this project. But cootos to them!!

One Man's Quest To Restore Florida's Coral Reef.

Ken Nedimyer is a man who's goal is to restore and save Florida's Coral Reef(s). When he was thirteen his whole family went on vacation to Florida and then he went back to   Florida for collage and stayed to live there. In 1977 some cold fronts hit Florida and the Staghorn and Elkhorn coral that wasn't killed was terribly wekend and later got infected with White Band Disease. And just as the coral started to get better in 1985 two hurricanes hit Florida and killed a lot of the coral, this put them on the endangered list. Ken and his Daughter decided to grow back, artificially, 
this coral and then place it back in the ocean. They got her high school to do it as a project and it was incredibly successful and after that they decided they waned to continue on with this project. Finally in 2004 they got their first 
granted permission from Florida Keys National Marine to start a project. Now in 2011 there is much improvement, however it may not be back to normal yet, but we have re grown and re planted coral over the entire Florida Reef Tract all the way to the US Virgin Islands

Dirt: the Movie

The movie that we watched in Science class about dirt was a very interesting video. There were many valid points in it such as how we need so save the dirt and make it as it once was; fertile, moist, healthy, and a good source for growing our food. Due to modern technology and chemicals used to preserve the food and kill the pests with pesticides it has caused harm to the soil, filled the food with toxins, and harmed the hydrological cycle, also harmed humans health, because they toxins get into the air and we breath the air and that can harm our bodies and possibly give us future cancer. Birth defects sometimes also occur here is an example:
This baby was born with no arms or legs because of what pesticides did to her mother while she was carrying. No one should suffer from birth defects or health problems because the industry wants to make some more money. However, they do benefit us as well, they allow us to grow more crops, faster, and makes them cheaper as well for less fortunate families and individuals.

Also look at the people who spray the pesticides on crops. Depending on the part of the world you live in, some are better equipped than other, for example, in India and China those workers are not at all protected and there is a high chance that they may get a fatal disease later in their life and may weaken their organs, such as their lungs and heart, and lower their immune system, who also work for very little amounts of money. While someone in America may be equipped with gloves, masks, and protection from the toxins sprayed. They may not get sick due to toxins, because they have the proper tool and equipment. So compare these two men and how their lives may be differ. Think of the man with all the proper tool and equipment, and how his future health may be, and how the man with no proper tools or equipments future health may be. This video about dirt was very informative, however to biased I think. It favored one side over the other, which is ok, as long as you give the positives and negative's of BOTH side. This video only focused on the positives of their opinion and the negatives of what they are against. They did not stat any of their negative's or positives of their opposing side. For me to form an opinion I would need to hear something more only stating the facts, not opinions,

San Diego Ocean Glows in the Dark!!!

 Click here for original article
Along California's coast in San Diego there is a phenomenon going on. It happens periodically and it is called Red Tides Usually it lasts only a short while, but this year it has been already three weeks!!!!! What causes the water to light up is these tiny little organisms called Phytoplankton. The reason it is not constantly light up is because it only happens when they dominate the ocean. It is still unknown to scientists why they light up in the dark, but then not the day. During the day the waters are a murky red, brown, or purple color. However, we do know how they light up. It is a chemical reaction caused when the cells hit against something. Right now what is happening in San Diego is that they are all being pushed upon each other and that is what is causing them to light up. The reason they are being pushed upon each other is because the ocean waves are banging them against each other and at this time they are dominating the ocean so the result is a lot of them get pushed and clumped together causing the beautiful sight. What I find the best, most interesting, and defiantly the coolest part about these phytoplankton organisms is that they are not at all that toxic so you are able to swim in these amazing waters! Simply just imagine splashing your friends with glow in the dark ocean water? Or the beautiful photos you can take and what makes the already legendary golden cost even more stunning and beautiful. What you can also do with these phytoplankton organisms, if you live close to the San Diego beaches, you can fill up a jar with the ocean water and share it with your class or just use it as a very cool detail added to your room. These organisms themselves are not that beautiful, but what they produce is stunning.

The Amazing Tale Behind Winter's Bionic Tail By Kavi Dolasia on 10/03/2011

Have you heard of the movie Dolphin Tale? Well that movie was based on a true story about a real live dolphin called Winter. In the movie they added a few aspects to make it more interesting. However there is a true and real story behind it. One day a man went to work and threw his crab catcher into his favorite sport and he heard a squealing. He went to go see what it was because it kept getting louder and louder. He saw that it was a baby dolphin stuck in the crab catcher and he immediately got his knife and cut it up. However, when the dolphin was let go the blood circulation to her tail got cut off so he called the Hubb-sea World Research Institution. They treated the dolphin and had to amputate its tail, otherwise it would die. They were worried because she still might have died. The amputated it and she started swimming again. However they were worried because she couldn't swim up and down so she started swimming side to side. They were worried that she would mess up her spine that way. One day they got a call from the vet and said they could make a fake tail extension for her. When they made it it was a complete success and now Winter serves as an inspiration to the rest of the world.

Glow in the Dark Shark! Disappear as well!!

For the Article below I found my information from another website and article, for the website click here

In this article they talk about a species of sharks that can glow when they want to and 'disappear' as well. Thus species of sharks is called Lantern Sharks, they are a rare dogfish shark. These sharks are found in the deep waters of the East China Sea and off the coast of Taiwan and Japan. Like I said before this shark can glow in the dark at its own will and when predators come they can make themselves invisible. What allows them to do this is their light emitting organs called photophores. The lantern sharks belly, tail, flanks, and pectoral fins light up in particular. When they light up, since they feed at the bottom of the ocean, they attract prey to them and that makes getting food easier for the lantern shark since the prey comes to them.  Also according to and quoting this article "To become invisible or camouflage itself against predators, the shark uses another neat trick, called counter-illumination. With the help of its photophores, it transmits the same intensity of light that is coming in from the sun above and blends in, so that all its predators who are looking upwards from its belly, (which is the only lit up section) see is a spurt of blinding light. And, it gets better. Since the shark has no way to regulate its brightness, it regulates its depth. During the day, when the sun is brightest, it swims deeper in the ocean, while at night, it floats nearer the surface, effectively remaining camouflaged as long as it wishes to." The shark controls its turn on and turn off with a coordination of hormones.

Current Event: Dolphins Dimples Detect Electricity by Shiki (tatjana)

My information comes from this sight and for more information I think you should check it out: click here to visit the sight.

   When we see dolphins we act with all out five senses, we see them, hear them, if we want to we can lick them and taste them, of course you would not want to, but you can. You can also feel them with your hands, and you can sniff them if you like, even though they don't have much of a smell. Well just as we sense dolphins, they do too, only in a different manner. Dolphins do not have all the same senses as we humans do, for example they have very good eye sight, but no sense of smell. Sensory biologist tried to understand these things and during their research they made an interesting discovery about the Guiana dolphin.

   Since Dolphins do not have a sense of smell the Guiana dolphin can detect electric fields, this is what replaces the sense of smell and helps them find many fish to eat. Scientists think that these dolphins are benthic eaters, this means they look for food on the sea floor. For most benthic eaters it is hard to find food dow there because animas make clouds of dirt and sand while looking for food and it gets mixed up with the water and then the water in no longer transparent and becomes opaque and then it is hard for the animals to see their pray. Finding food with being able to sense electric fields makes it easier for these animas to get around.

   This sense comes from their snouts. "Living organisms generate electric fields. The beat of the heart, the work of a cell, and the pump of gills all produce tiny but measurable electric fields. In 1992, scientists  even measured the electric field produced by small goldfish" - What ever you do makes an electric field, when you talk, when you quite and when your brain is working everything creates and electric field. And animals also create electric fields in many natural ways. Scientist though that the dolphins electro sense may have something to do with the small dimples on their snout called vibrissal (pronounced "vy-BRIS-uhl") crypt. Scientist though of what its function must be so they tested it. They tested on two Guiana dolphins from M√ľnster, Germany. First though, the scientists took tissue from a 29-year old dolphins snout who died of natural causes. The vibrissal looked familiar under a microscope. Scientists found out that they looked similar to sensors used by other animal to detect electric fields. Also they found nerve fibers running into the pits and that is a sure sign of electrical activity. Next the group of scientists studying this dolphin tested out on a live 28-year old dolphin named Paco. They tested him to see if he would recognize an electric field. they trained him to do a few things such as to swim close to the device that created small electrical fields in the water. They also trained him to swim away from the device to a treat he liked (a fish probably). When the scientists would flip the switch Paco would be trained to swim away if he notice any changes in the electrical field. When there was no electrical field he would stay put and now swim closer or farther away. When they put plastic over Pacos snout he did not react to the electrical field, because his vibrissals we covered and therefor he could not sense the electrical field. After these tests the scientist working with Paco confirmed that he used his snout to detect any amount of electrical fields. 

the dolphins in this image are a couple of Guiana dolphins swimming in the Atlantic ocean and Caribbean sea.

PSA Presentation Reflection

In class we had to make a Public Service Announcement about safety in anything and how Inertia is involved in it. I chose to do safety in horseback riding, because I train it so I know a lot about it. I learned about the positions in horseback riding, and how inertia is involved in it, like when the horse starts a canter you feel a tugging force in your back. That is inertia. I also learned about friction, momentum, and Newton laws of Motion. The first one is Inertia that any object stays in rest or in motion unless acted upon by an outside force. An example in horseback riding is that when a horse starts in a canter you feel a force pulling your back and if the horse were to abruptly stop you would go flying forward because your body wants to stay in motion and then the floor is the outside force that causes you to stop. From my class mates I learned a lot about how inertia and momentum an friction cause things to happen in car accidents, motor safety, poet safety, rowing safety, airplane safety. It tells you how weight also affects safety in those things. I think that it is important to understand the science between accidents because then it can show you how to prevent it form happening again and it can show people to stay safe and live longer! All hail Science!!!

Marble Motion Lab Report

Guiding Question and Hypothesis
   Our guiding question to this lab was does the weight make the turns of the ball different, does it make it turn, go  straight, or swivel? I was curios about that because I know that when you blow air on something that it changes direction. It can either go straight, curved, or swivel off from side to side. My hypothesis was that the heavier things would go straight and the lighter objects can curve or swivel. 

Table/ Diagram
type of ball straws used length it went  weight 
big marble 2 straws 128 cm heavy
medium marble 1 straw more than 136 cm medium/ heavy 
small marble 1 straw 137 cm light
tennis ball 2 straws 70 cm light/ medium
small Styrofoam ball 1 straw 95 cm light
big Styrofoam ball 1 straw 137 cm light
ping pong ball 1 straw 137 cm light

Data Analysis
During this Lab I recorded how each ball traveled. The big marble was heavy, went 128 cm, and we used two straws, bust most of all was the way it traveled, it traveled in a curved fashion. The image to the right shows the way the big marble traveled. The average sized, or medium marble, was blown with one straw, it went more than 136 cm, and it weight was medium/ heavy, and it traveled straight, it did not swivel or curve.  It shows you below how the medium marble traveled
The small marble was blow with one straw, it went a distance of 137 cm, had a light weight and traveled straight. It shows you on the left how the small marble traveled. 

tennis ball
For the tennis ball we used 2 straws , it went 70 cm, it had a light/medium weight, and it traveled and a zigzagged or swirly way.   The image above shows you how it traveled. 

small Styrofoam ball

The small Styrofoam ball was blown with one straw, it moved 95 cm, it had a light weight, and as you can see, it traveled in a zigzagged and swirly manner. To the right there is an image showing you how the ball traveled. 

The image to my right is showing how the big Styrofoam ball traveled. It went in a zigzagged and swirly line. The distance it traveled was 137 cm and it has a light weight. 

The image to right shows you the ping pong ball. It went all zigzagged and curly swirly, it had a light weight, we used 1 straw, and it traveled 137 cm. 

I think that the mass of a marble does affect how it moves because the more density and mass it has the straighter it moves and the less of it it moves  more swirly, curved, or zigzagged. I think that when force is given to an object the motion that is happening is the wind is blowing on the object and forcing it forward.

Who Owns the Ocenas Minerlas?

In the world there are wealthy countries and less wealthy countries. To mine in the ocean a country needs to be wealthy and have a coast line, countries with no coast line have a harder time mining the oceans minerals. The reason a country has to be wealthy to mine in the ocean is because to mine the oceans minerals  high-tech, complex, and expensive machinery is required. It is the cheapest to mine at the continental shelf because it is shallow and the deeper you mine the more expensive it is because you need bigger, more complex, and high-tech machinery.

In the year of 1944 the world made a treaty called the international seas and they made limits to how much a country could claim. In the treaty it said that no country could have an entire ocean to itself and that they had to share. They said it was an internationals water way. That means that that they are international waters and they belong to every country in the world. Also the little bit of water in between two pieces or areas of land are still counted as international waters, because they are so useful. E.E.Z. which stands for exclusive economic zones are extending the right to get minerals offshore. Also there was a law made that said you could not test nuclear power in international waters. In World War II the continental shelf was used by people as something to use a land grab.
                                                                                              The image below is the Arctic

 There is global warming in the world, the reason we are not sure of. Some people who are greedy with minerals think that as a good thing, but I think of it as a bad thing because it causes animals to die and the pollution in the air also causes animals to suffer and die. There is also 25% untapped oil and natural gas, but however it is underneath the ocean floor. The reason some selfish people think it is good is because then they can have another ocean where they can mine and get minerals from.
                                                                   The image below shows you the location of the Pacific
In the Pacific Ocean we mine there for, mostly, salt because it has a large amount of it and is easy to get. Salt is a very important substance that we use every day in food, preserving things, cleaning, on roadways, and more. Where we get and take the most salt from is Mexico. In the Pacific you can also find Lead, Bromine, and Magnesium. Mining in the Pacific Ocean is very important because we use many minerals that come from the Pacific ocean every day.

                                                                The image below shows you where the Atlantic is located

Some of the most common minerals found in the Atlantic are Calcite, Limestone, and Dolomite. Those are very important minerals to everyday life because we use them in so many things. From all over the world people are fighting for them because they have many multiple values in them. And some examples are that the uses for calcite are medicine, toothpaste, and building materials. There are also more. Limestone is used in the purification of sugar, making paper white, medicine, and is aggregated in concrete, and those are only some of the hundreds of uses it has. 

Because of all these debates you may ask who owns the minerals. Well in my opinion I think that no one owns them. I do have a solution though, for example poor countries can trade with countries who boarded the ocean, and wealthy countries can pay countries who border the ocean to mine there.

To conclude this I think that the minerals belong to everyone, but some boundaries have to be made. I also think that the oceans do not belong to anyone. I hope that after reading this you formed an opinion, changed your opinion, or had more to back up your opinion!
