PF TA PF TA PF PERIODIC TABLE!

  PF TA PF TA PF PERIODIC TABLE! PF TA PF TA PF PERIODIC TA- Oh hey guys, didn't see you there. I was just making a rap about the periodic table. And yes, that's what we'll be learning about today. Let's get started. OK, so the periodic table is a chart that shows all of the elements known to man. The person who made this chart was a guy called Dmitri Mendeleev. He was the youngest child of 18 kids! 17 SIBLINGS?! Gosh, I can't even handle one!! He was born in Tobolsk, Siberia in 1834. He studied at St. Petersburg and then later became professor! He then arranged the 63 known elements into a chart called, you guessed it, The Periodic Table!! Obviously, the periodic table has been modified a bunch of times. They change it because they find new elements and they need a place on the chart. Speaking of new atoms, they named an element after him!! It's called Mendelevium.



cool beard















       Now on to the actual periodic table. There are 118 elements on it. Yeah, I know, that's a lot of elements. But, elements over 92 are too unstable to be made in nature so it has to be made in a lab. If you guys were wondering what 92 is for, then I'm about to tell you. If you weren't thinking that, then plug your ears because you're not allowed to hear! Just kidding! The "92" is the elements atomic number. That shows how many protons are in their atomic nuclei. The atomic number is at the top and under that is the elements symbol. The symbol is the 2 or 3 letter abbreviation for the element. Like Helium would be He. Under the symbol is the name of the element. And finally, under that is something called the atomic mass. That is exactly what you'd expect it to be, the mass of an atom. Basically, it's how much the atom weighs. Since most of the mass of an atom is in its nucleus, it's technically how much the nucleus of an atom weighs. Here's a picture of how an element looks on the periodic table:



see, this is how Helium looks












         Elements are put in order from there atomic number. They are also put in these things called groups and periods. Groups are elements with similar configurations of electrons. They are put in vertical columns and are numbered 1-18. Periods describe the number of electon shells that have elements have. Do you remember learning about electron shells? They are what electrons orbit on. Well, each element gets an electron added to thier shell. So the first one, starting from the left, has one on it's outer shell, and the one on the other end, the right side, is completely full. Sorry for confusing you all but hey it's not MY fault your brains don't process this information!! Haha just kidding!!





                       

        Another thing you should know are catagories. These are elements that have the some properties. There are 7 different groups. Alkali metals, alkaline earth metals, transition metals, poor metals, semimetals, nonmetals, and noble gases.

  

     That my friends, was the periodic table. I hope you liked!! Ok, now on to our next topic. Oh you thought the blog was over????????






IT IS! Science Fun:)

YOU THOUGHT THE BLOG WASN'T OVER

Total History Secion Today!

   Hey everyone!!! Well today is gonna be totally about history. Weird right? But who doesn't love a little history? Anyways, our topic is gonna be kind of sad. It's about 9/11. As you guys know, last Sunday was the 10th anniversary of the terrible terrorist attack that happened in New York. This was the worst tragedy America ever had. It killed more people than the attack of Pearl Harbor. So sad...


AW!








    It all started at 8:46am on Tuesday September 11, 2001. A hijacked plane flew into the North Tower of the World Trade Center. At 9:03 a second hijacked plane flew into the South Tower of the World Trade Center. All bridges were closed around New York and New Jersey. Every airport in the country was closed, that was the first time that every happened. At 9:45 a third hijacked plane crashed into the Pentagon. At 10:05 the South Tower collapsed. At 10:10 a huge part of the Pentagon collapsed. Also at 10:10 the fourth hijacked plane crashed in a rural part of Pennsylvania. The only reason it didn't crash into some other monument was because the brave people on that flight confronted the hijackers. Then, at 10:28 the North Tower fell. The damage had been done.



a picture of what plane went were

 

















        These terrorists were part of a group called Al Qaeda led by Osama Bin Laden. They had been planning the attack for years. For some reason, they hate us. No one really knows why but they do. I don't get why either, I mean we are awesome! Anyways, they were hoping that this attack would break America apart. But we did the exact opposite. We came together more of a country than we ever have. It showed them and the rest of the world that we Americans are strong. We can do anything if we put our heart and soul into it. It showed the world that we are not weak.



the American flag













    Every American knows about 9/11. You always feel emotional when you hear about it. Everyone now feels sad, sick to your stomach, shock, and just overall bad. People in the future will probably feel just as bad. They might not have as much emotion because they weren't actually to witness it. But they could always do stuff to remember it. They could look at some pictures, watch a video, or better yet, visit the memorial. If your wondering what the memorial is, let me tell you so your brain can be filled with even more knowledge. Basically the memorial is were the Twin Towers once stood. It has a waterfall and all of the people's names that tragically died there. The place is now called Ground Zero.



this is what one of them looks like. the other one looks identical













    Lots of things came out of 9/11. Both good and bad. The bad is all the lives lost and the damage that happened. The good is how much America came together and the new Freedom Tower they're building. This will be at Ground Zero and will be a whole lot bigger and safer than the old Twin Towers. It will be 1,776 feet tall. They want it to be this length because in that's when America got our independence, 1776. Plus, they are making it with lots of precautions. So it's gonna be really safe.



this is how it's planning to look





















     9/11 was such a terrible event in our country's history. It killed over 3,000 people. It really was the worst tragedy of our country's history. But hey, we made it. Even if it is a thing of the past, it still happened. We should celebrate this day by a simple day of rememberance. Remember the people who died on those planes, the heros who risked their lives to save others in the towers, and the brave people who confronted the hijackers and made the plane not crash into another building. We Will Never Forget. Science Fun:)



   

History In Science Class? WHAAAAAAAAAT?

     Hello my fellow people of the world! So as you might have read from my title, we are gonna have a little history mixed in with our science. (we are?!) Yeah didn't you guys read the title? (uh we were supposed to?) Yes, yes you were. But it doesn't matter! Anyways, what we will talk about is the history of atoms. First thing is who had the first idea about atoms. This dude's name was Democritus and he lived in like 2400 BC. Here is how he looked like: 



      So now we are going to get to know our dear friend Democritus. Let's call him Dem for short. HEYYYY DEM! Anyways, Dem was born  460 BC in Abdera, Thrace. No, I don't know where that is so don't ask. He did live in Greece though. Dem was one of the best Greek philosophers. Not much is known on his life though. He was also a mathematician, but he was known more for his tribute to science. SCIENCE NERDS RULE! Isn't that right Dem? 

haha you know it! 

      That was a little bit about Dem. Now let's get down to the science-ness of it all. Democritus asked, "What id you could keep cutting something forever?" His theory was that you can't keep cutting something forever, eventually you'd get to the smallest most tinniest piece which is impossible to cut anymore. He called that tiny piece "atomos" and he pictured it looked a little like this:

ignore the democritus part

      Well when he told all the other philosophers, they really didn't care. Dem was like, "Hey guys, I think that there's this thing called atoms which is the smallest particle of something!" And the other philosophers were like, "Yea that's cool and all but I'm gonna go listen to Aristotle." POOR DEM! And who was Aristotle you ask? He was the most well known philosopher of that time. He had a different theory. He thought that everything in the world was made up of water, earth, fire, air. He proved this by burning a log. The flames coming out was fire, the ash was the air, he used water to put it out, and the stuff left over was earth. And that simple little experiment was able to win everyone over. Here's a picture of Aristotle. 

      The sad thing is that poor Dem's idea didn't get recognized till 2,000 years later! Poor, poor Dem. But hey, at least it got recognized! If you want to learn the stuff that I didn't teach you then you can go here:

      Sadly, Dem's idea got ignored for 2,000 years! Man, Dem really isn't that lucky! Well at least it got recognized! Even if it took a long time. Well, I think you guys got the idea about the first atomic theory. Since you were all so good, I'll give you a video. Goodbye my fellow people of the world! Science Fun:)

What are we gonna talk about.....

      Hey guys! So I really don't know what we are going to talk about today but I'm sure that we will figure something out- (ring ring) Oh one second.


 *me on the phone* Hey Steve! Where are you? *Steve my pet unicorn* NEIGH! *translation*. I'm at Om's.*me* Oh OK! Well bye!


   So good news guys! I found our topic today! We are gonna talk about... ATOMS!! Alrighty then, the first thing we are gonna talk about is what an atom is. Well, basically an atom is the smallest thing EVER! For example, take a piece of paper. Cut it in half, then keep cutting it until you cant cut it anymore. Your ending result is an atom. Atoms are really small. So small, you can't even see them! But, trust me, they are there. And where exactly is there? There is everywhere! Basically, atoms make up anything and everything. People, animals, plants, trees, lamps, chairs, and even air!



that's an atom boys and girls!











  Now we know what an atom is. Yay for us! But now we need to talk about the structure of atoms. Well, an atom has a thing in its center called the nucleus. It has these things called protons and neutrons which we shall talk about later. Ha ha I love that word, shall. It sounds so fancy. Anyways, outside the nucleus is this thing called an electron which we will also talk about later. The electron is moving at almost light's speed around the nucleus. It's moving so fast it looks like there is a fuzzy cloud around the nucleus. Another cool thing about the structure of an atom is that it's mainly empty space. Here's a picture:


















      So now we are going to talk about the stuff I promised we would talk about. And those are protons, neutrons, and electrons! Let's start with protons. Protons are one of the subatomic particles that are in the nucleus, just as I said before. They are kinda heavy, well as heavy as you can get for a subatomic particle. They have a positive charge. JUST LIKE ME! Click Here to learn more about protons.

this is supposed to be the nucleus of an atom

    Now on to the neutron. Neutrons are also in the nucleus. They are always right next to the protons. Neutrons really don't have a charge, they're just neutral, hence the name neutron. They are just as heavy as the protons. Click Here to learn more about neutrons. Oh and did anyone else think of  Jimmy Neutron when I said neutron? If not you are definitely thinking about it now! 

I used to LOVE this show!! 

     Last but not least, we have the electron. Electrons are much smaller than the proton and nucleus and have a negative charge. For every electron there is a proton. This makes the atom even. But, sometimes an atom loses an electron. Bye bye electron! This makes the atom more positive. However, sometimes an atom gains an electron making the atom more negative. Click Here to learn more about electrons. 

aw he has such a big nose! 

    Well, that's it for this atom's blog! Hope your brain is filled with new knowledge! Now, I have to go, I have to get Steve from Om's house. I'll leave you with this atom's song. BYE GUYS! Science Fun:)

SCHOOLS BACK!

      Hey guys! (heyyyyyy) Guess what? (what?) IT'S SCHOOL! (mutter mutter) Yeah I know but the good news is I'm gonna do blogs again!! (sarcastic yay) Excuse me? (YAY!) Better. Well Right now I'm not doind science-y blogs. I'm gonna talk about my summer! 

haha its so creepy!!

    So as basically what I did this summer is hang out with friends. You know, had a couple sleepovers, went to the mall, went to the movies, went to the pool. By the way, I beat my record of staying up at a sleepover, I stayed up till 7:40am!! WOOP! And I saw the best movie in the history of the universe... HARRY POTTER AND THE DEATHLY HALLOWS PART 2!!!!!! Oh my god it was so good!! VOLDEMORT HAS NO NOSE!! I mean seriously watch this and say it's NOT amazing!!





  OH MY GOD IT'S SO GOOD! But probably the main highlight was having my British cousins coming. Their names are Rami and Danny. They were awesome! They had the most AMAZING British accent ever!! Haha we went to White Waters, Georgia Aquarium, pool, mall, restaurants, everything! They were so much fun and I can't wait to see them again. Plus they're British!! I love British people! If you're British then you are my friend. 

  

its true

    Well that was my summer! But I'm not done yet..... I'm gonna tell you guys what I want to improve on this year. I really wanna get straight A's all year! That means I need to really need to do good at one thing... VOCAB! I'm not that amazing at that. And believe it or not, I wanna get better at my blogs! I know what you're thinking, (but she's already amazing!) well I wanna get even more amazing! I wanna try to put more info in them and less of myself. So it can be more informational but not boring. So yeah straight A's and better blogs. If I do that I will be really happy!! 

haha that's exactly how I'd be! a creepy smiley person! 

                                                          

   Well that's the end of this back to school blog! I'll be back next week with my first science related blog of this school year! See you guys then! BYE!!! Science Fun:)                                                                       

I NEED WATER!!!

     Ugh it is SO hot! I don't know WHY I ever chose to walk in the desert! Hey, look its the Nile River! YAY WATER! Oh god, I hope it's not a hallucination...



please be real!














     Ah, better. Well, I learned something when I was there. I learned about this new virus. It's called the West Nile Virus. Well I bet you guys are thinking, "How do you get it?" You get it from mosquitoes. Ugh I hate mosquitoes. But basically, they come and bite you, however that mosquito needs to have the virus. So, you're talking a hike or something, and then this mosquito comes and bites you. At first you think, it's just a normal mosquito bite. But the reality is, it's much more than that.



EWWWWWWWWWWW! I HATE MOSQUITOES!














     A mosquito bite from regular mosquito is no fun. But a bite from one that has the West Nile Virus? Absolutely no fun. Symptoms from West Nile start appearing 5 to 15 days after being bitten. You usually have these:
-severe headaches
-fever
-nausea and vomiting
-disorientation
-chills
-muscle aches, pain, stiffness
(If you have any of these symptoms after getting bit by a mosquito, call a doctor!

this is what you should do

    Before you start freaking out, let me tell you how to prevent it. STAY AWAY FROM MOSQUITOES! As in, when you go outside, make sure to wear bug spray. Also, try to have DEET in the spray. Try not to let mosquitoes breed. They can breed in any place that has still water. Cover pools when you're not using it. Stay away from water at dusk and dawn, that's when mosquitoes are most active. But sadly, they are still active during the day. Lucky us...



yeah, I don't think that's gonna get rid of him...





















     Here's some more good news. This virus rarely affects people. It mainly affects birds. You may have seen a bird randomly fall out of the sky. Scientists usually take the bird and test it for West Nile. But, even if a human does get it, there really isn't anything you can do. It just goes away by time. They do have a vaccine, though. Yay for humans! We can prevent it! We can stay healthy! Woohoo!



her name is Suzy














        There still is a lot I didn't cover about this topic. So, I'm gonna give you a link. Click Here!!!!  There are four different sections. There's also a comic! Be sure to look at all of them! Alrighty then, that's my blog on West Nile! Bye!!! Science Fun:)



PEACE OUT!!!!!



Idk why this posted! haha it was on accident!

     Ugh it is SO hot! I don't know WHY I ever chose to walk in the desert! Hey, look its the Nile River! YAY WATER! Oh god, I hope it's not a hallucination...
