Camouflaging Prey

At first glance, all you see is leaves. Look again. Do you see that? That bird over there? It has to look like a leaf to survive. Survive being eaten by the hawks in our neighborhood. It is prey, nutrients to many, but to survive, it camouflages. But without the tree, the bird will die, but without the bird, the tree will not be affected in any manner, so it is also a form of commensalism. Thanks to its camouflage, this bird lives to see another day

Limiting Factors

This is a biotic limiting factor found in our local neighborhood, the bush. This bush is a limiting factor because it limits the amount of sunlight and water that reaches the ground and the other vegetation. It also limits the amount of shelter it can give to bugs and or other animals. But this is not a population due to the fact that it is a single organism not many.

The Aquarium




On Friday, our unit went on a field trip to The Camden Aquarium. It was an awesome trip, even though we didn't get to everything. There were touch pools, hippos, seals, penguins and a lot more! The first thing our group did was touch the sharks, that is nurse sharks of course. When a shark started coming my way, I stuck two fingers into the exhibit and felt the flank of the shark. I was surprised, a lot of people said it feels like your ear or it feels like your nose, but actually, it was squishy like your stomach and a little bit course like sand paper. The next shark that came around, i touched its back. That time, it felt more like your ear except a little bit more squishy. We left that exhibit and went outside to go see the seals and penguins. All the penguins were guarding their own little patch of territory. The one penguin that claimed the shower, seemed to have a smile on its face. Next, we went to go see the seals. There was one on top of a rock in the middle of the pond, tanning. As I looked more closely, I realized it had finger nails and toe nails just like humans. Its back was wrinkly and filled with blubber and so was its neck. Every now and then, it would lift up its flipper and rubbed its eye. After that, we saw sharks in the shark tunnel with other fish. I wonder if the fish are scared of the shark. Then we saw hippos. Did you know that birds poop every fifteen minutes? The hippos were sleeping and the fish inside of the tank, were cleaning the hippo. The rest of the day, we saw all kinds of interesting animals such as the shark ray. From underneath, it looked like a stingray from up top, it looked like a shark. I think that the shark ray is the boundaries between the shark and the sting ray, they are both very closely related. The cnidarians we saw were bio luminescent, they would light up. The puffer fish I saw, had a little smile on. It wiggled back and fourth like it was dancing. The field trip was a blast. I learned so much about sea creatures and saw cool animals.

Science Mysteries Answered



Many people like the delicious popcorn. But how does one tiny hard disgusting kernel, become a puffy popcorn???? I took this to the next level, I searched and searched for the perfect answer to my question. Through my research I have found, that a popcorn kernel needs 4 things, to make it pop. The first thing surprised me a little. Popcorn needs to have somewhere between 16% to 19% of water. The next critical thing on the list is, The actual kernel has to be strong enough to withstand the steam inside of the popcorn until the inside is fully cooked. Next, the outer shell of the popcorn has to be perfect, no dents or cracks. I thought that that was pretty obvious. Finally, the temperature has to be perfect for enough steam pressure to burst the kernel in to delicious nutritious popcorn.






Another interesting science mystery has yet to be answered. In school, I did a lab, a lab unlike others. We filled an ordinary soda can with a little bit of water, we heated it up, and dunked it into ice cold water. We heard a pop, like a balloon. I took a look at the can, it was crushed. I couldn't find a definite solution for this awesome mystery, so I made a hunch. I knew it was something that had to do with air pressure. I also knew that hot air is denser and cold air is not. The last piece of information I knew was that hot air rises and cold air sinks. But all those don't matter for my hunch. From chemistry, I learned that hot air expands while cold air huddles. My guess is that when the water in the can was hot, the molecules expanded. But, when it came in contact the the extremely cold water, the density disappeared and the popping sound occured because the can shrunk and got squashed.

Frog Dissection


A couple of days ago in science class, we did a really cool dissection. A frog dissection. The frog was bigger than I expected, it was about 8 inches long and 5 inches wide. The pattern on its stomach was really cool, it had a cream color back round and light gray leopard spots on it. When I made the first cut, it thought it would be as thick as human skin, but it was like cutting fabric. When my group mates pinned the skin down, when i was cutting the muscle, it was like cutting a rubber band, but more fabric like, such as the skin. When we fully pinned down everything, we got our first glimpes at the frogs insides. You could easily the liver, (the three lobes) and the stomach, (the tube like organ). We had a chubby frog so the spagetti like fat bodies, were every where. Pulling out each and every fat body took longer than thought. Next we cut out the liver, which was very hard. We saw the little gallbladder and we popped it, we saw the bile in it excrete out. then we saw the jumbled brain like small intestine. We took that out and measured it, at its full lengh, it was longer than the lengh of the frog! We cut open the stomach to see what it last ate, nothing was in there. then we took out all the organs we already saw, and I located the spine. Someone else located the spleen which was read and full of blood. Finally time was up and the dissection was done. that was the most funnest, dissection ever.

Breeding Has Made Dog Heads Very Diverse


Scientist have ejected research into dogs even further and they have found out that dog skulls shapes have evolved faster than cats and walruses. Every breed of dog skull are evolved at a different rats so the skulls are very diverse and have a wide range of shapes. Since humans use selective breeding to breed for the better, we seemed to have chosen a certain skull shape over other because the make the dog appear better so in the last 150 years dog skulls have evolved faster than any other mammals. But the canine family has dated back to 60 million years and no leap that big in evolution has occurred. Experts wanted to know how the degree of skull shapes varied and they led test. the results show that a collies head varies from a Pekingese's head and that it resembles more of a cat shaped head. In the wild, such drastic changes would occur in a mush more slower rate. In the wild, a canine needs to survive, but once they are domesticated, that no longer applies to there nature. For dogs, we breed them to do what we need them to do best and that doesn't necessarily mean to hunt or to run really fast but to do the jobs that they were bred to do. But in the recent years, many people have now bred dogs for their look than more of what they do. such as the Sheltie went through such selective processes, they are one of the most beautiful dogs on the planet. In the next century, the dogs heads might change once again.

How Math Relates to Global Warming

Math can almost relate to everything, so can it relate to global warming? Global warming is caused when the number of ozone molecules decrease. One ozone molecule is is 3 oxygen atoms, but certain gases such as CFC halon easily gets split into atoms by the uv rays that come through atmosphere. But the split atoms will rise to the ozone layer and destroy ozone molecules. If the apropriate amount of trees are divided so they will produce enough oxygen to help the ozone, then global warming will be solved! the whole entire solution for global warming is based on math. Also, we can use math to know how much electricity we really need so we cut down on power usage. Alot of other ways to cut down on using also lies within the useful knowledge of math.
