Who: People working at an aluminum plant didn't take safety precautions causing the reservoir to burst.
What: Human error caused a spill. The liquid is red with iron in it. It can cause skin burns and if the dust is inhaled it can cause lung cancer. It is also slightly radioactive. The government will try and clean it with water to neutralize the substance. Dams were built to prevent the spill reaching Romania. Predrag Maric quotes " the spill isn't dangerous but can still pollute our water supply".
When: 5th of October 2010
Where: In Western Hungary. It spread throughout Hungary.
Why: The spill occurred due to the reservoir bursting. Safety precautions weren't done so this is what happened when people are careless.
How: A chemical spill happened.The reservoir burst causing a flood and destroying everything in it's path. It reached the Danube and if it reaches Romania it will go to the Black Sea and from the Black Sea it will go to the Mediterranean Sea. From the Mediterranean Sea it will go the Indian Ocean. Hopefully there won't be that must water to flood the Indian Ocean.

Obesity and the common cold
-Stephen Ornes
Site: http://www.sciencenews.org/view/generic/id/63992/title/FOR_KIDS_Obesity_and_the_common_cold
Summary:
Research shows that obese people ( people that have too much or extensive amounts of fat) are causing an epidemic. If a child is obese, they will most likely become obese adults. Obesity is caused by poor nutrition and lack of exercise. Another study has shown that if a child has/had adenovirus-36 they can become obese. A test was taken out of 57 children to see if they had antibodies to fight off this virus. Tests showed that only 19 had antibodies. This test proves that if children and adults maintain a healthy lifestyle they won't get this virus which would later lead them to not being obese.
One World:
The article Obesity and the common cold connects to what we are learning about by being current science news. It effects scientific knowledge by giving scientists a new look on antibodies and how the body mass effects the amount of anti bodies. It effects technology by making doctors make new machines to help people loose weight and antibodies. It also effects technology by making new drugs for the virus adenovirus-36. This article effects society by raising awareness about obesity and forcing people to maintain healthy lifestyles. The limitations are creating anti bodies for obese people. The benefits are people getting profit from drugs and people using their machines to get antibodies. Also there will be more healthier people.
Analysis/Evaluation:
The scientific information was searching to see if obese people have enough antibodies and if adenovirus-36 causes obesity. This article made sense because here were quotes and it was on a science site. I made one inquiry. Firstly, how can we stop adenovirus-36from making us obese?
Reflection:
From this article I learned three things. Firstly, that being obese as a child you can bring it with you into adulthood. I thought that you can stop it but not always. Secondly, that obesity is an epidemic. It sounds odd but many people get fat and this is quickly moving around the world. I thought only diseases can be epidemics. Thirdly, there is a virus that can make obesity. I thought only you can cause you obesity but since there is a virus people must stay extra safe and healthy to not catch it. In conclusion I found this article interesting and helpful. The ideas above are what I learned.

Atom Video
http://www.101science.com/Chemistry.htm#Chemicals_and_Interactions
This video was overall quite interesting and helpful in understanding the atom. I learned quite a few things:
- Electrons don't orbit the nucleus
-Atom(uncuttable)
-Reflective light is too big for an atom hence can't take pictures of them
-You can't know the location or momentum of an electron
-You can only know the probability of where it can be
-More likely to find it in the center but it can vary
-Function of where an electron is= orbital
-If protons, electrons and neutrons had velocity it would orbit
-# of protons= what element it is
-Atomic mass- protons=# of neutrons
-Isotope= same element with a different number of neutrons
-99.99% of something is free space
In conclusion I enjoyed learning from this video because the facts were repeated and stuck into your head.

Green Plastics
From watching the video Green Plastics I have found out how normal and bio plastic effect the world. Plastics are being developed by making their production Eco-friendly. Bio plastic is made from natural resources which can be reused and recycled, the only problem is that it takes a lot of energy. Yes, bio plastic is recyclable unlike normal plastic but pesticides and gas is needed to maintain the production of bio plastic. Most people wouldn't recycle so it would be the same as normal plastic. What makes green plastics are natural resources being used and being recycled. Some issues with these plastics are as I mention before energy being used and harmful substances to keep the production of these plastics. In this video I saw three elements: oxygen, hydrogen and carbon. I saw about three compounds. It was these elements put together. The connection with this video,the article about water and Blue Gold is that showing the importance of keeping our environment clean because every possible way of pollution effects water, in this case pesticides and gases.
