A Hole in the Ozone layer above Arctic

Record Arctic ozone hole raises fears of worse to come

Uh oh there is a gaping hole in the ozone layer! It is right above the Arctic. It is the biggest hole in the northern hemisphere. The ozone layer protects us from UV rays which can give us skin cancer and, or cataracts. Scientists are worried that this is might be annual, because they have noticed it every summer since 1980. What is destroying it is chlorofluorocarbons. That chemical is man made. Also. the hole gained size in March.

I hope this is not annual, if it is this could be very bad for everyone. I also think that the UV rays are very serious. My suggestions are; reduce, reuse, recycle, and walk or ride a bike do not drive unless you absolutely have to.

A Solar Storm gave a glancing blow to Earth

Solar storm delivers "glancing blow" to Earth

 The sun made a solar storm. Solar storms are just what they sound like, storms. They are a lot of wind which we got a bit of, that is why scientists call it a glancing blow. Solar storms can mess with satellites. The storm was rated either strong or severe. During this storm it did not really do anything to our satellites, but this is not the worst one there will be. A worse will be in 2013. That is it's eleven year solar cycle. The storm was not bad because where it was pointing towards the Earth, if it was the storm could have been much worse.

When I read the title of this I was really confused, I had no clue what it was, and that is why I chose that passage. I still do not completely understand how it is made but I know the basic idea of a solar storm.

NASA satellite is going to crach

Defunct NASA satellite tthis weeko crash to Earth

NASA is saying that this week a satellite will crash back into Earth. The name of it is CAPE CANAVERAL, it doesn't work any more. It will happen most likely on Friday, but it could be Thursday, or Saturday. The satellite will split into around twenty six pieces.They could land almost anywhere. The biggest piece will way around 331 pounds, or 151 kg. The chance of any of the pieces hitting you is one in 3,200, so don't be worried about it. It will probably land in the ocean or a patch of land where nobody lives. The satellite worked for fourteen years, but no it does not work anymore and it is being pulled by Earths gravity, and that is how it is happening.

I think that this passage was very interesting. A part of that satellite could actually land here in Serbia. One of my questions are that how do they know that the satellite will split into about twenty six pieces? Also how do they get the odds "1 in 3,200"? Another thing I found interesting was that when satellites have came down in the pat they have never hit any one.

NASA's deep-space rocket

NASA has made many advances in their technology. We have spent decades exploring the moon. We have learned so much about it and know we can learn about other planets. NASA might be able to launch a rocket to far off planets in 2025 but they have money cuts so the launch might be postponed until they get enough money. They might be able to explore the other planets. Maybe they will even find out if there is life on Mars.

I think that their advances in technology are outstanding. When you think about it, it is amazing. We may get to learn about other planets. Maybe NASA can continue their advances in this if they could get to the planet made of diamonds in the Milky Way Galaxy. I chose this article because it caught my attention. I think NASA is very interesting.

My Knowledge

I do know a fair amount about the living and the non living. Fist of all, I know a few things about cells, they have two main types, plants and animals, but then those cells are put into many subcategories. Also some of the things that animal cells have are, nucleus which controls the cell, a wall which keeps things out of the cell,  and a vacuole which stores things in it. Plant cells are mostly the same except for shape,     (plant cells are rectangular, and animal cells are round) and chloroplasts. With non living and the living I know that  the living has to have many different standards, like cells, responses, and cellular organization. If they are missing just one thing they are not living. What I do not know and what  I want to know is,  how many different types of categories cells can be sorted into, and how scientists knew what part of the cell does what.

My Science goals

Last year was a great year , but there is still more things I need to work on making longer and more descriptive current events. That is because, in seventh grade you have higher standards. I think to do that I need to get more descriptive information with a bigger story. Another thing that I want to do, is to get better in physics. To do that I need to take more notes when we get to that section. Lastly, I want to make better lab reports. The solution to that problem is to just work a bit harder on them.

Scientific Summer

Over my summer vacation I went to Ireland. It was really beautiful. One of the most scientific things we have done this summer was that we went to a poison garden. It was filled with many plants and an explanations. If you are in Ireland I would recommend going to the Blarney castle, because that is were the garden is and it was very interesting. The garden was filled with about 30 luscious but poisonous plants.

















The science of what I did was Botany . Botany is the study of plants.These were poisonous plants. Some were lethal, but others just made you sick. The American Mandrake is a plant that can kill you. The plant looks like an umbrella. It can grow to be about 18 inches. Another one of the plants in the garden was called Wolfsbane.  They sometimes used it to put on the tip of arrows for hunting and war. Wolfsbane is fatal. The cure for it is human fecal matter. I will also tell you about Rhubarb. The leaves are toxic but the roots are not. People actually eat Rhubarb (roots) and like it. They say that it is very good.
