Yea Amanda that is so great! The red sparkles really DID spread around like viruses. I have something interesting to add as well. I have an example for viruses. One type of virus that can cause illness is the flu. The flu is easily transmittable. Maybe a mini-story will help. Say a woman with the flu goes to the grocery shop. When she’s looking through the diary products, she sneezes and doesn’t have time to cover her mouth. The germs get onto the milk and settle. The woman hands the infected milk carton to the cashier. The cashier then scans it and the virus gets on her as well. The woman leaves. Think about it. The cashier rings up over 100 customers PER DAY!!!! Each person has their own lives and probably touches over 100 people as well. If one of the people happens to fly to a different country than the people that person touches will get infected as well!!!! If this was a REALLY BAD virus the whole world could DIE in a pretty short period of time!! Luckily there are many smart people out there that invent many types of medicine to help cure viruses like this. =) Daniel: Yay can the whole world really die in like, 2 days?

Amanda In class Mrs.McDaid placed small glitters on the papers that were getting handed back. You noticed later on that that was on your friend from a different class then you saw it was on a high-schooler 3 grades higher than you. How did this happen? Well in our world we have trillions of bacteria on and around us we can pass on these bacteria when we shake hands, share drinks, close contact, exchange of bodily fluids and so on. We can pass it on to one person that person can pass it on to another and another can pass it on to another person or more get it? Now we live in a time where we can travel places in planes and we can go to all sorts of places. That bacteria can spread there and then a person from there and go too some were else and spread it there. This can affect the hole world by just this process. Luckily we have vaccinations and antibiotics to cure and prevent our bodies from this bacteria. YAY!!! Daniel: Yay! We have antibiotics, but I don't think they have antibiotics for **every** bacteria do they? =Joanna= Have you ever wondered how something as small as a bacteria cell can affect a whole entire human race or animal race? I don’t know if you have or not, but you probably can’t imagine how big the effect would be if something went wrong. We did this activity in class how the helpers who handed out the papers (me and Tiffany) put our hands in glitter to represent the virus. We didn’t let anyone know that we had glitter on our hands. Of course, the glitter got everywhere on the papers, floors and tables. It even got on some people’s hair! That is how easily viruses and bacteria can be transmitted like that. It can be as fast as the wind or in the wind itself! Some people who are sick probably sneeze on their hand and think, “ok, when they turn around, I’ll quickly wipe it on my pants.” But little did they know that only half of the viruses and bacteria got off. The other half are probably still on the hand. They will touch their hair, face, mouth, chairs, people and all sorts of things, transmitting the cells farther and farther away. Then, later on, they keep sneezing and find out that they’re diagnosed with some sort of deadly unknown disease! That means that thousands of miles away or people right next to the original person have a 50/50 percent chance of catching the disease! The people will get it, carry I on to other people, and the next thing you know, the whole world has it, making people die! So that’s how easy spreading a virus or bacteria can be, and how big the affect would be if a something as tiny as a bacteria cell can affect the world.

=Daniel= media type="custom" key="3212544" Harschal: I'd love to say something but I cant see anything, its a blue box with a question mark..try reposting it. Mrs. McD: The requirement for this entry was a picture and at least 100 words...could you please add that to this page? Ok so Heres my typed answer. How does something so small affect a organism/community/planet? Well if we start with one virus in a human body it could be insufficient to destroy anything. But give that virus a cell, and it will be able to multiply to unbelievable quantities and can do massive amounts of damage to your body. Take Adolf Hitler for example, if it was only him then he couldn't even do anything, but give him a easily manipulated and starving country, and you have a war that everyone will remember forever. The virus will manipulate and make the cell produce more bacterias, and not only virus can do this, so can any other small microrganisms! [] =Harschal=

How does something so small affect an organism, community or planet?

How does this tiny bacteria affect an organism, community or planet? It all starts from one little cell. The cell reproduces and produces 2 then 4 then 8 then 16 etc... A bacterium for example could invade and we would be affected by a bacteria/virus. Virus's/bacteria are known to spread and thats exactly what they would do. The virus's/bacteria would multiply and eventually spread from an organism to a community and eventually a planet! This is how one little tiny thing can affect the entire world! All it needs is to reproduce which takes time. Sources:

I chose this picture because it was a bacteria which is small and that is what affects the organism/community/planet.

( I needed to repost becuase mine was deleted, so nothing was copied. )

Byron: It not only takes time, but the temperature is in it. Karen: Can a bacteria really spread around the entire planet?

Back To Top =Byron= http://www.rkm.com.au/VIRUS/Influenza/FLU-images/VIRUS-FLU-structure-L-500.jpg A microorganism affects a whole community by just being small in size and hard to track down. Bad viruses and bacteria can come into our bodies without us knowing. They take over our own cells, and reproduce to spread the infection. These can give us anything from the common cold to AIDS, and can be spread around rather quickly. This can start from just a kid, to his parents, to the kid’s school, and it just keeps spreading everywhere unless we are careful to keep safety measures in mind. This can even cause an epidemic. This is how a something so small affects an entire organism. I chose this picture because it is an influenza virus, something small that can affect us.

( A couple people had to repost theirs, including me)

 Teddy: A good example of havoc caused by the epidemic is the black plague and sars.

How does something as small as bacteria’s, viruses and protozoan affect an organism, a community or even a planet? Well, from what I’ve learned, a bacteria doesn’t only affect the planet’s organism, it actually enabled the planet to be able to bear most of the organisms we know now. How this happened was, back in the old, OLD days, the only organism the planet had was pretty much archaebacterias, one of the six kingdoms of organisms classified by scientists. The planet used to be a really harsh place, with all the hot swamps and barely any oxygen. Only archaebacteria, with their toughness against harsh environment, were able to habitat in. These archaebacterias actually slowly changed the world by producing oxygen and changing nitrogen up a little so the animals and plants later created by god could respirate and thrive. (I actually posted this before Herbert but someone deleted it, so don't say I repeated his idea...) http://images.encyclopedia.com/getimage.aspx?id=2792724&hero=yes

A tiny bacteria or virus can infect bigger organisms like us.It can infect any organisms of the six kingdoms. First of all a virus is a non-living particle that invades a host and reproduces inside the host. A virus is so much smaller than a cell by the way! It injects its genetic material into the host and takes over the cell's functions. Then it tells the cell to make more copies of the viruses so that it can infect OTHER CELLS!!! There are pathogenic viruses, which are the harmful ones and harmless viruses that reproduce and leave the host. The pathogenic ones can harm the tiny cell inside an organisms by infecting all the cells of the organism. Once the organism is infected, the virus can also travel to other organisms, easily by physical contact. When you hear the word "bacteria", you might also think that it's very harmful or can make you sick. But guess what? Most of them are actually helpful. They help you digest food, make vitamins, and help make medicines. Without bacterias, you won't be able to receive the good vitamins. Although there are some harmful bacteria that cause diseases or make you ill. For example, the bacteria in you stomach that causes stomach aches. These tiny organisms can protect you and at the same time harm you. The also protect our environment and the world! The picture below is showing the bacteria in our intestine that helps us digest food. http://fasting.ws/juice-fasting/wp-content/uploads/180/acidophilus.jpg Herbert:nice!

 * How does something so small affect an organism, community or planet? **. Bacteria is a large group of micro unicellular organisms. Bacteria are one of the oldest life on our planet.It is thought that bacteria evolved 3.4 billion years ago. Archebacteria and bacteria were one of the first life forms on planet earth. Back then there was very litle oxygen. by using photosynthesis they filled atmosphere with hospital air/ oxygen so we organisms can breath. So if there were no bactria in general we wouldn't be able to live on this planet. There would be no oxygen, and none of the six animal kingdoms inhabiting earth. We might even be able to live on some other planet but we human would function completely diffrent from the way we do here.

yiying: herbert, i agree with you!

Cassandra's comment: That is awesome writing Herbert! =Yiying=

=[|Bacteria.doc]= =Cassandra:=

How a something so small affects an organism, community, or planet is by sexual reproduction or conjugation with bacteria. This is when bacteria combine their genetic material; this creates a variety in bacteria but not more. Why conjugation can affect organisms, communities, or the whole planet is because two organisms that exchange genetic material can create a brand new kind of bacteria. One that we never knew existed and because these bacteria have never existed, our bodies along with other organisms could react to this new kind of bacteria in a weird way. We could get deathly ill, or even die, and then again it may not even affect us or it might even be helpful. Yet if it were to kill us and other organisms, such as plants, and the bacteria couldn’t be contained or killed in time it could kill all of us. One of us, an organism could be infected and killed, and then if it spreads a community of us could be killed. Then all of us could be killed, erasing us from the planet, killing all of our kind. Meaning that we would all die changing the world to a place without humans!

A small organism like this bacteria could affect the whole world!! Dhalyn: I love you cassie. nice answer btw. Karen: Interesting. You mentioned killing everyone so many times. Don't we have antibiotics to cure most bacteria? It would be really insane if everyone died. I don't think that's possible. XD You had a lot of good points, too. =D

=Julie= After reading other people’s answers, I agree that most bacteria are either harmless to us, or they are actually helpful. Only some kinds of bacteria are harmful to us, such as the typhoid fever. However a tiny little cell can really change ourselves, communities and our whole planet! For example if you drink or eat somebody’s food and a harmful bacteria infect them then there is a high chance that you will get that bacteria in your body. Like I said before, most bacteria are good, so those good bacteria can actually help us a lot, for example they make some of the most popular food like cheese, yogurt and olives. Some people really like to eat these foods, so without bacteria their favorite food will not exist and everyone’s eating habits will be very different. http://www.ou.edu/class/pheidole/General%20Bacteria.jpg

Karen: Awesome. I dunno what my favourite food would be if there was no bacteria to make cheese taste so good... Matthew: Yay for bacteria! I love cheese.

=Karen= How does something so small affect an organism, community, or planet? Well, here's one way a community can be affected by something so small. You've heard of archaebacteria, right? They're the kind of bacteria that abled living organisms to live on earth. They do/did many good things for us, but have you ever thought about the bad side of them? This type of bacteria gives off methane, which produces a stinky smell. That's why swamps, or sewages smell so bad. Since living organisms such as you and me don't want to be surrounded by foul odors all the time, we avoid these places with bad smells, such as swamps. That's probably partly the reason why you wouldn't find a house in the middle of all this. You wouldn't want to live here, would you?



[] Julie: Very special entry Karen! Your the only one that talks about the bad side of having bacteria. =Galahad= How do something so tiny affect the earth? It is all because of reproduction. Virus multiply by injecting the DNA in the virus in to the cell. The DNA uses the machinery in the cell and reproduce in the cell. once it is have so much virus that it have to burst out of the cell and the cell would die and the virus will go invade more cells in the body. Eventually, when you cough or sneeze the virus will all come out and go invade other organism on the earth.IT does the same with bacteria. The bacteria multiply within 20 minutes if it have the food it needs and the energy. That is called Binary fission. Sometime the bacteria Conjugates their genetic material so the can live on the place. The go near each other and send out a tube then genetic material goes through the tube into the other bacteria. Now, they both have the same thing of each other and they can live on the place. Soon it is going to come out the the place and invade other organism and reproduces more.

Virus invading a cell.This is a bacteria conjugating [|Back to the top:]

=Matthew=

Something tiny like a virus or a bacterium can affect a community because there could be a virus that fixes all the damaged cells that are messed up. This could cure diseases. There could also be a bacteriophage that only destroys harmful bacteria. This way no one could get a bacterial disease in the first place. There are also helpful bacteria that help us live. If these bacteria disappeared we would not live very long. www.flickr.com/photos/47353092@N00/350398704

=Tiffany C =

** Just because it is small doesn’t mean you can underestimate it. You can’t judge things because of their size now, can you? When a harmful, and very deadly, virus infects your cells, it can easily take over your body in a matter of time. Each virus can only infect a certain type of cell in a certain place. When a virus does inject its genetic material into the cell, it will either be an active virus or a hidden virus. Either way, it will multiply and make copies of itself. Eventually, the cell will burst open and all the viruses inside it will spread. So think of this: all the viruses that were just made will inject other cells, and eventually, all the cells in the organism would be infected. If the organism has physical contact with other organisms, the disease/infection will spread. Eventually, everyone in town will have it. After, everyone in the country, continent, and soon, the entire earth will catch the disease. Then, there would be nothing left of us humans, or even any other living things on earth. Picture: I chose this picture because you can see a lot of viruses attached to the cells. ( I kept re-posting, but then I couldn't save because I was going to erase someone else's work, so if it disappeared, I'm sorry, I tried my best to not overwrite it ) [] **
