Final Ultimate Survival Reflection
I first did this mind map to help me write this reflection. The mind map shows mostly the things we have covered in things we have covered in this unit. So the "big idea of this unit was to understand how to balance between man and natural environment, transform resources into human goods, and understand us and management of natural resources. I think things that helped me really understand these things were projects like the packaging project, this helped me understand the transformation of the natural resources we have into things that we want (sometimes need). Another thing that helped us understand the bid idea was the blog posts we did. These gave us a chance to reflect back on each new thing we learned and doing them online is much easier and more fun. Last but not least, Watching the films really made the information stick. This is because it gave us visuals that really stuck in your head like, for example, the eggs in the Human Footprint.The question for this unit was, What is a necessity and how does an organism ensure the survival of it's species within it's environment?. Well a necessity is something that is not wanted but needed. If this thing is not obtained it has dangerous and maybe even life-threating effects on the organism. For example, food, water and oxygen are all necessities for humans because we need these things to survive. I think an organisms ensure the survival of it's species by adapting to it's natural environment and then reproducing so that the next generation is then fully suited for the environment which it enters. This unit question helped us to view survival through the areas of interactions. How? Well we were shown that everything almost "interlocks" in a way. This means that everything you do effects a chain, which effects another chain and so on. Even if you are not face to face, or touching the other organism or environment you can still effect it. In this unit I would have liked to have more of these hand ons thing. Becasue the whole unit we talked about how we effect the environment so it really just made you want to get out there and help. So I think we should have gone out and seen first-hand what mega-pollution is really like and then maybe helped by cleaning. From my point of view we covered all of these thing quite well, the ecosystems part with naming the exact species in an ecosystem, etc. we never really elaborated on, but I think that would be taking it to the next level. So all in all I think it was a fun but long unit.

Letter To Canon
I am a student who did a project on the packaging of different products. I looked at your cartridges that are made to "fuel" the printers. While looking at your package I found that there are many layers and non-recyclable materials. Maybe corrugated cardboard would be better because this would allow the cardboard would be able to be recycled. I also think maybe making the packaging smaller with less plastic might be a possibility as well. Aside from the negative aspects of your company, I think that the steps your company is taking to make it more environmentally friendly are very impressive and I did not expect that. I thank you for taking the steps to going green. Going back to the negative side I would like to ask a question. Is it necessary to have so much paper for instruction in so many different languages? As a consumer I have to admit that I rarely will read the instructions and if you have a picture that is all you truly need. I was wondering if there are any other steps you will be willing to take in terms of helping the environment. I have another question where do you make most of the products and from where are the materials supplied from? Also around how many cartridges do you make in a year? I hope you write back and maybe listen to some of the tips that I included in this letter.
Sincerely,
Maria- 7th grade

Green Plastic
Green plastics are develpoed by taking chains on polyactic acid which all come together to make polyactic acid oligmers, when due to a chemical reaction become lactide which then become PLA which is the most manufacture type of bio plastic.
What makes these plastics green?
The substances they usually come from is corn, sugar cane, or sugar beet. This makes the natural, biodegradable and renewable. Which pretty much makes them quite green.
What where some of the issues mentioned with the packaging?
Well the packaging can cause effects like:
-Growing corn which makes us use more pesticides, herbicides.
-This also leads to using trucks and these use oil and gas and then emit carbon dioxide.
- We could start using to much food for plastic and end up in a food crisis
- Use to much land for crops
- Bio plastics can biodegrade and give off methane.
How might these green plastics change packaging practices?
It might change it in terms of making the packaging more eco friendly and making our planet better.

Current Events: Can cacti escape global warming?
I chose this article because we are doing products on packaging and how if you do not recycle it effects your environment, so I chose to do this current event because it explained an effect of global warming. I think that to prevent even the predicament of having plants that are trying to protect themselves against global warming would not be happening if we could better sustain our planet and we can do this by recycling, turning off light, etc. So many little things can help.

Owl Prey graph and pie chart
Answers to questions 1,3,5 in packet.
My data collected:
5.50%- Birds
1.11%- Shrew
20.32%-Mouse
31.44%- Vole
41.61%- Rat
1. Looking at the data we collected as a class I think that the prey that is most frequently consumed by the "owl population" is the Rat. This makes sense because rats are big which means nutrients and more food for the owl. Yet also rats are fast breeders and their are lots of them. Also rats are usually slower and less quick making them easy prey.
3. I think the smarter choice between 35 insects at 1g each or one 35g vole when looking at conserving energy is definitely the vole, because both of them will give you the same energy value if you didn't have to hunt for them. Since you have to find each insect, which would mean you would have to hunt, eat, hunt, eat, etc., you are wasting the energy you just collected on hunting again yet with the vole you simply catch, eat, rest which means in conclusion you will have much more energy.
5. Looking at the data we collected you will see that the percentage of shrew in an owls diet is 1%, which is not very much at all. So if the shrew population declined I doubt it would have any to no affect whatsoever. This is because shrews are such a small part of the owl diet they really do not depend on them.

Current Events: What killed these whales?
I chose this article becasue I think whales have been the focus of many problems when it comes to the interaction between them and us. Meaning we are profoundly effecting them with our habits. This is important because the whales we lose cannot be replaced naturally as fast as they die unnaturally meaning this could effect the food chain or Eco system in that area. I think that this ties into our unit that we are finishing up which is all about Eco systems and how small things effect the bigger picture. I think the best way to prevent whale mortality is to not use the sonar equipment in areas which have whales in them.

Human Footprint
8,086 eggs in my lifetime
12,129 newspapers in my lifetime
16,172 glasses of milk in my lifetime
I will drive 270,465 miles in my lifetime
4,043 bananas in my lifetime
100 sodas in my lifetime (This is because I do not drink soda that much)
28,301 shower in my lifetime
8,086 potatoes in my lifetime
1,095 slices of bread in my lifetime.
For me something I could do is to cut down on newspaper and instead read the news online. Yet if I do have to buy a newspaper I should remember to recycle the newspaper. This is mainly my human footprint. A human footprint is what we consume and how it makes an impact or imprint on the earth. We have to learn how to make our footprint less "deep" and make it have less of an impact.

Current Events; Whales and Sunscreen?
Proceedings of Royal Society B was the first place where this study was published. It shows how the damage of the whale’s skin due to the sun is on the rise. This is most likely because the ozone layer is thinning which is increasing the levels of ultraviolet radiation. They get sunburned because they have to come to the surface to breathe yet there is no hair, feather or fur to protect from the rays. Hiding in the shade is how some other animals have adapted to this predicament yet whales cannot do this. Karina Acevedo-Whitehouse, a postdoctoral fellow at the Zoological Society of London and her colleagues have looked at this problem, and together they have preformed skin biopsies and photo surveys in the Gulf of California on blue, fin and sperm whales. In this region, which is near the tropical latitudes, the dosages of skin cancer radiation are much higher than in the mid-latitude zones. With stainless steel dart skin samples from 2007 to 2009, all the skin cells collected were sunburn cells/ abnormal cells these are cells that have been DNA damaged by ultra-violet light. This was found even on the lowest layer of skin. Due to the over exposure of ultraviolet radiation researcher believe that these sunburns will worsen over time. For this hypothesis they tested on blue whales while bite marks and the other skin problems remained unchanged the blisters from sunburn became noticeable. Darker whales such as sperm or fin whales tend not to get as sunburned as lighter whales do, similar to humans. Yet some of these whales spend more time on the surface making them still prone to sunburn. Scientists have only recently become aware of this, since this year marks the 25th anniversary of when the hole in the ozone layer was discovered. Even though e hope that the ozone levels will return to the 1950’slevel by 2080. Yet this is a lesson from the ozone hole on how quickly our planet can change or how we can change it.
This article interested me because it made me ask questions, how do whales get sunburn? Since we just finished our one world essay presentations which really talked a lot about effects of humans on the environment this is another very good example of how we affect our world.

Current Events: Free as a bird.
I found this article interesting because I thought birds are only picky when it comes to the area they lay and eventually hatch their eggs in. I did not know that birds actually rely on landscaping and how "natural" the area is to not only lay eggs but also pick a mate. I think this topic ties in with our unit because we just finished our one world presentations, which mostly talk about the effects that humans have on animals and the environment. Well, this is a good example, because if we continue to keep on cutting down trees and then building roads, buildings, etc not only will birds be forced to inbreed but deforestation will also be a problem.

Current Events: Bedbugs are Back
I found this article interesting because it was something that I had heard on the news, and was scared(which helped me understand what they said in the article about emotional damage) So reading this helped me understand more about bedbugs. This ties into our Unit 1 about interactions because what we have here is a type of a symbiotic relationship, the kind of relationship which is known as parasitic. This relationship between bedbugs and humans is actually, from my perspective, kind of in the the middle between Parasitic and Commensalism.

Current events: Another Earth!
Probably having a solid surface and being in the "Goldilocks" Zones which allows temperature to be stable and making sure it is not so hot that water boils or so cold that it freezes. Gliese 581g looks pretty substantial for life. For thousands of years scientists have been searching for an earth like planet.And since 1995 they haven't another planet. But they don't know yet whether there is life on this planet. "We're pretty excited about it," admits Steve Vogt of the University of California at Santa Cruz, a member of the team that found the planet. "This is right next door to us. That's the big result."
I really like this article because when I was in 3rd grade we studied global warming and I got very worried that the earth would burn up and the human race would have nowhere to go. Yes, I now know that will logically probably not happen but it is nice to know that there is another planet that scientists have found. I think this ties into our unit about ecosystems very well because this planet is an ecosystem that is being studied.

Current Events: Move over, Ticeratops!
Move over, Triceratops! Maria L. , 7A, 9/29/10, Science
The Triceratops has always stood out among other dinosaurs because of its great horned face and head. But due to a new discovery it looks like the Triceratops wasn’t the only dinosaur to have pretty impressive head gear. In southern Utah two new giant horned dinosaurs where found recently, and have been named Utahceratops gettyi and Kosmoceratops richardsoni. Both of these dinosaurs are part of the same family as the Ticeratops. Something that is similar in all these names is the the word Ceratops which means Horned Face in Greek. The reason all these dinosaurs have this in their names is because they all have horns on their face. The Kosnoceratops richardsoni was an impressive find because of its interesting skull which has 15 bony horns and is the most decorated of all dinosaurs. “ Kosmoceratops is one of the most amazing animals known, with a huge skull decorated with an assortment of bony bells and whistles,” says Scott Sampson , research curator at the Utah Museum of Natural History and host of the OBS television series Dinosaur Train. How did the Utahceratops gettyi get its name? From the state in which it was found, combined with ceratops .And gettyi is includedbecause of the person who discovered the dinosaur Mike Getty. Kosmoceratops richardsoni is kosmos which means “ornate” combinded with ceratops. This then follows with the part that honors the founder, Scott Richardson in this case. The site of excavation for both dinosaurs is located in the Grand- Staircase-Escalante National Monument. This site covers 1.9 million acres and rests on what previously was Laramidia. It is the largest national monument in the U.S and one of the last undisturbed dig sites for dinosaurs.
I thought this article was interesting because not only did I learn more about dinosaurs I also learnt about how the dinosaurs are named and a lot of Latin terms. I think this has quite a positive effect on the world because this can also help us later on discover more dinosaurs. I wonder if the species and the Ticeratops had any other things, except for name and the same kind of face with horns, in common. Did they eat the same things, live in same environments, etc.Since scientists have shown that the more complex a creature is the better chance it has of survival. So in conclusion since these dinosaurs are so complex they probably have quite a could chance of survival. This is an adaptation and this is what this article has to do with our unit.

Reflection on Mr.Watts' presentation
- What interaction between these animals did you notice?
- Why do animals migrate?
- How do animals know when it is right to reproduce? What conditions are they looking for?
- Adaptation of animals in the Antarctic usually include having blubber so that they can keep from in winter if they do not migrate. Migration is also when where when the climate is too cold animals simply move to a warmer climate that is more pleasant. Teeth, like in some seals, help they break through they ice so that they can get air from the surface. Also one bird which has a huge wing span
, instead of flapping its wings, uses them to glide in the air. And the colossal squid has hooks on its tentacles so that when it grabs onto prey the only way the prey can go is into the squid’s mouth.
· What various breeding rituals did the animals have?
One ritual was with elephant seals in which the bull (male) would challenge another male a fight by bellowing. The males are fighting for all the females, so the winner will be able to breed with all the females in the group. It is usually the biggest who win in fights like this. Also when the male wins he is somewhat “in charge” and he decides what goes on in the group.
· When do most large animals reproduce? What does it depend on?
Most of the big animals need food for their young so they mate at times where the food source in there region is plentiful. So it depends on the time of year and season because this is what dictates when the food source is supplied.
· How did this presentation provide examples of what we have been studying now?
It showed us examples of animals reacting in ecosystems. How they adapt, when they reproduce, when they feed, what happens when it gets cold, literally how they survive in such a harsh ecosystem like the Antarctic. It also helped because the examples weren’t general they were quite specific each about a species of animal.
· What are you wondering about now?
I am wondering whether it is possible that different species, examples Gentoo and Macaroni penguins, ever end up accidently or possibly purposefully breeding together. Would this only be possible if there were very small numbers in a group and two groups came across each other? Or is it simply impossible? But species of bogs sometimes mix but do they have different mating restrictions than humans.
· How did Mr. Watts help tie in everything that we have been discussing during this unit?
He helped us understand how intricate ecosystems actually are. By explaining in great detail of each little part of the ecosystem the whole idea of what the ecosystem is actually about comes together much easier, somewhat like a jigsaw puzzle. I understood that the Antarctic is harsh but also has much more life then I would have thought.
The Antarctic is a cold place and not much life there, but it is much more of an interesting and complex ecosystem and the organisms that do live there are very interesting.

Current Events: Microscopic Frogs
A frog the size of a pea was discovered by Drs. Indraneil das and Alexander Haas of the institute of biodiversity and environmental conservation at the university of Malaysia. The species was found on the side of the road that lead to the summit of Gunug Serapi Mountain which is located in Kubah National park. The frog that was found is called scientifically Microhyla nepenthicola. And it is a frog that is about the size of a pea (Males are usually 10.6-12.8 mm) This frog is found in Southeast Asia, Borneo and lives in the local pitcher plants. The frog depends on the pitcher plant to raise it's young. The frog lays it's eggs on the side of the pitcher plant and the tadpoles grow in the liquid inside the pitcher plant. Hence the fact that the name of the frog, Microhyla nepenthicola, was based on the name of the plant that it uses to grow it's young, Nepenthes ampullaria. But since these are such small creatures how did the scientists ever find the rest of these species? These frogs where tracked by their call and then made to jump on to a piece of white cloth. The frog has a particular call which is a series of harsh rasping sounds that go on and are interrupted with short intervals. This "song" continues from when the sun sets till the early hours of evening. Amphibians are the most threatened group of animals with 1/3 of the population gone. This is because amphibians are quite sensitive to changes to their surroundings, so discovering these new miniature frogs helps scientists understand what changes that occur in the global environment are having an impact on amphibians.
I found this article the most interesting out of all 3 because it was something I had never heard of before and was such a recent discovery. It also intrigued me that something so small could play such a big part in a ecosystem or on the survival of a species. It helped me understand that the discovery of even something so small can help us understand the other parts of this frogs ecosystem. If you want to learn more visit: Frog Site

Survival
- Is there a certain chemical in the brain that trigger the instincts that animals have?
- With magnetism and migration how does it work?

Living Things and the Environment.
- Food or Supply of Nutrients
- Shelter
- Ecosystem
- Water
- Sunlight
- Oxygen
- And a stable temperature for the organisms
- Abiotic and Biotic which create the habitat.
- Species
- Population
- Community
- Ecosystem
- Biomes
- Biosphere
- Because different species have different needs so they go to habitats where those needs are fulfilled.
Think about what will soon start happening within Belgrade. How do animals prepare for such a change?
- One thing around this time that happens is that since the weather gets colder animals that have no form of protection against the cold go into a deep sleep for several months, this is called hibernation. During the period before hibernation the animals will gather food for the time after they finish their hibernation.
