...Where did all the frogs go? Imagine years into the future from now, the newly born kids won’t even know what a frog even is, how sad would that be? No more familiar ribbit in the middle of the night. Amphibians are still very important to humans, to the ecosystem, and to predators. If the amphibians become extinct, they will be nothing but a memory. Frogs control pests like flies, mosquitoes, and other insects that have the capability of carrying a disease. If a mosquito is carrying a disease and bites a human, they could get malaria, which can cause death. Frogs decrease the chance for humans to get deadly diseases like that. As amphibians decrease, problems may increase. Loosing fifty percent of the amphibians would put them almost extinct; they are already on the endangered list, which wouldn’t be good if we lost even more of the population. Conversationalists think that because amphibians are small, they are not as important to focus on, but they are wrong. Like mentioned above, amphibians control the insect population. The loss of the amphibians will also cause their predators to die as well. Amphibians have been teaching us many things; they have been alive for 350 million years, surviving dinosaurs, meteors, and also humans. That is a long period of evolutionary success. They adapt to wide range of environments like deserts, forests, and ponds. They still teach us things today, like new medicines and cures that are used from the chemicals within...

...teacher if Korea had any scary stories. “Kumiho, the Fox with the Nine-Tails”, he said. Of course my interest was peaked and so he said, “Kumiho is a nine-tailed fox who eats the hearts of humans in order to survive. She digs up graves sometimes to find hearts or attacks men.” He couldn’t tell me much more so I dug up some info. Unfortunately it all seems like the information is taken from a commentary on a book that holds the oral stories of Korea, Compendium of Korean Oral Literature. This is more or less taken from Wiki and all other sources that say the same basic information: A fox that lives a thousand years turns into a Kumiho, like its Japanese and Chinese counterparts (the kitsune and the huli jing). The current Japanese kitsune can sometimes be evil and sometimes good, but the Korean counterpart over the years has become a symbol of evil. Legends tell that while the Kumiho is capable transforming its appearance, there is still something persistently fox-like about it. In Transformation of the Kimono, a Kumiho transforms into an identical likeness of a bride at a wedding. Not even the bride’s mother can tell the difference. The Kumiho is only discovered when her clothes are removed. As the mythology of the Kumiho evolved it was later believed that a Kumiho had to consume human hearts in order to survive. Another version of the mythology, however, holds that with enough will a Kumiho could further ascend from its Yokwe state and become fully, permanently human and...

...Blossom and Grueba Blossom and Grueba Deep in a swamp in a faraway town lied a lily pad community known for its marshy waters and remoteness, called Caymaris. Within its population there was a beautiful bullfrog named Blossom whom every one envied, for her long green legs, slender torso, and stunning emerald eyes, she was the talk of the bog. Other Inhabitants all prayed one day to be as alluring as her. Though Blossom was the fairest Bullfrog in her town, her sister Grueba did not have any of these attributes. She was polar opposite of Blossom, the kindest, hardworking Frog you could ever meet. She was always willing to lend a helping hand to anyone in need and volunteered to deliver food to all the hungry frogs of the town. Her torso was compact, round, and her eyes were off centered and as black as coal, and the legs she used to carry out her kindness were short and stumpy. Blossom never wanted any of the bayou to know that Grueba was her sister, for she thought she’d be ridiculed. Daily Blossom would go about her routine of awaking dressing prim and proper even styling her hair with a neatly done ponytail and a gigantic white bow adhering it together. While Grueba's hair was always a mess, and all the kids teased her and called her names. Every morning on their treacherous walk to school across the wetland and through the forest Blossom would be sure to stride far ahead of Grueba, to ensure that none of her classmates could see that they were sisters...

...only you can grab it. So, demand and work steadfastly. Before Michelangelo could make impossible possible in his painting of the ceiling of the Sistine Chapel, he had seen the unseen as a visualization in his mind. No one else saw the impossible dream until it was finished in 1512. My heart bleeds to say that with growing age comes constantly fading credence to dream. We seldom realize the incredible power that we have within us; the power to believe in ourselves & live our visions. Ironically we tend to focus more than needed on the criticism & pessimistic talks pelted on us making us believe in 1000 reasons to not set out fearlessly to achieve the dream that we have. I would like to share the story of 3 Frogs that I read a while back: There was once a bunch of 3 tiny frogs, who arranged a running competition. The goal was to reach the top of a very high tower. A big crowd gathered around the tower to see the race and cheer on the contestants. The race began… No one in the crowd really believed that the tiny frogs would reach the top of the tower. They shouted, “Oh, way too difficult!!! They will NEVER make it to the top” and “Not a chance. The tower is too high”. The tiny frogs began...

...Bizarre extinct frog brought back to life March 16, 2013, 10:55 am By environment reporter Sarah Clarke ABC Imagine a frog that can swallow its eggs, brood its young in its stomach and give birth through its mouth. The gastric brooding frog existed 30 years ago, but the extraordinary amphibian is now extinct. In a world first, a team of Australian scientists has taken the first major step in bringing it back to life. They have successfully reactivated its DNA and produced an embryo. Professor Mike Archer from the University of New South Wales is part of the team, which also includes researchers from the University of Newcastle. He says the amphibian was no ordinary frog. "In the stomach these eggs went on to develop into tadpoles and the tadpoles then went on to develop into little frogs," he told ABC radio's AM program. "And like any pregnant mum, when you have little babies rattling away in your stomach saying, 'let me out', she would then open her mouth and out would pop little frogs. "The first people that saw that were aghast. By the time anybody got excited about it, suddenly it was extinct. "So that's certainly one of the driving reasons why this would be a focal animal for seeing if we can de-extinct this amazing frog." That is exactly what a team of Australian scientists is doing. After locating a few carcases stored in a deep freezer, they have been able to recover tissue from the gastric brooding frog. Using a laboratory technique known as somatic cell nuclear transfer...

...Frogs vs. Toads Frogs and toads are “small, tailless animal” that belongs to the amphibian class. (Forester 536 & Gibbons 303) Everyone thinks that frogs and toads are different from one another but in fact “there is no clear distinction between” them (Burnie & Wilson 440). Most people find it very difficult to differentiate between a frog and a toad that they often mix them up. Their physical features are very much alike but they are different on the basis of anatomy and habitat. When you see a creature hopping along the side of the creek, can you tell if it’s a frog or a toad? Frogs are very unique because “some frogs have colorful markings” (Forester 536). While as toads are marked in a “drab shades of brown, tan, gray, or black that serves as camouflage” (Campbell 217). Besides their markings, “almost all frogs have the same basic body structure” (Forester 536). Frogs have “long, powerful hind legs, which they use for jumping” (Forester 536). “Frogs can leap long distances, but also use their limbs to swim, burrow, and even to glide from tree to tree” (Wake 337). Unlike frogs, toads “generally have squat bodies and short legs” (Campbell 217). They do not “jump” like frogs so they “make short hops or even walk” (Campbell 217). As opposed to skin, frogs have “thin, moist skin” (Forester 536) and “the skin of most toads is dry, rough, and covered with warts” (Gibbons 303). There is an advantage to a toad’s dry skin. It’s “warty skin allows it to inhabit drier regions than...

...made an unusual discovery of a new species of frogs. The strange looking new amphibian is known to be a sole surviving member of amphibians that evolved more than 130 million years ago. Scientist calls this species discovery as a ‘once in a century find’ because of it’s belonging to an ancient group of amphibians that once shared the same land with dinosaurs. Formally discovered in 2003, the poignous frog, also known as the “Purple Frog”, has been the talk of all scientist discoveries because of its comic features and behaviors. Although this new species has recently been discovered with highly distinctive and comical appearances, its behaviors adaptive values benefit the amphibian by increasing its total fitness. However scientists might now be able to research this rare species because it is slowly decreasing in population. The purple frog has a sidesplitting appearance with a distinctive habitat in an unusual range of geographical location. This new species of frog can be described as a typical frog at first glance but as you pay closer attention you notice its distinctive appearances compared to other species of frogs. The body has a similar shape like most frogs yet it has a plump bloated body shape with short fore and hind limbs that end in webbed feet with rounded toes. Each hind foot has a large, white wart look-a-like growth that is most likely used for digging in their moist soil locations. The small head shape of the frog seems almost too small for such a short body...

...Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek an-, without + oura, tail). The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is found in tropical rainforests. There are approximately 4,800 recorded species, accounting for over 85% of extant amphibian species. They are also one of the five most diverse vertebrate orders. The body plan of an adult frog is generally characterized by a stout body, protruding eyes, cleft tongue, limbs folded underneath and the absence of a tail. Besides living in fresh water and on dry land, the adults of some species are adapted for living underground or in trees. The skin of the frog is glandular, with secretions ranging from distasteful to toxic. Warty species of frog tend to be called toads but the distinction between frogs and toads is based on informal naming conventions concentrating on the warts rather than taxonomy or evolutionary history; some toads are more closely related to frogs than to other toads. Frogs' skins vary in colour from well-camouflaged dappled brown, grey and green to vivid patterns of bright red or yellow and black to advertise toxicity and warn off predators. Frogs typically...

...tree. On the ground at its feet, something strangely familiar hops by: a frog. Ichthyostega, prehistoric predecessor to the modern frog, lived 370 million years ago during the Devonian Period. Sometimes referred to as "the first four-legged fish," skeletal remains of this earliest-known amphibian were first discovered in East Greenland. Surprised? Few people realize just how ancient frogs are. For 190 million years, the ancestors of modern frogs have roamed (if not ruled) the earth, looking much the same as they do today. The secret to their success is their amazing adaptability. As amphibians, frogs have one webbed foot in each of two worlds. The advantages of this double life are clear to see: Are land predators giving you trouble? Dive into the water. Not enough to eat in the pond? Hop out and see what they're serving on shore. Frogs have evolved to live in an astounding variety of climates. They can be found just about anywhere there's fresh water, from the desert to the Arctic, on all continents except Antarctica. Though they thrive in warm, moist tropical climates, frogs also live in deserts and high on 15,000 foot mountain slopes. The Australian water-holding frog is a desert dweller that can wait up to seven years for rain. It burrows underground and surrounds itself in a transparent cocoon made of its own shed skin. Frozen Wood Frog Like all amphibians, frogs are cold-blooded, meaning that their body temperatures change with the temperature...

The group of students range from seven to nine year old. Evolving achievements for several third grade students it is likely that they go through physical development at this age group include stable development example. At this age their gross motor skills are more developed than their fine motor skills. Elementary students learn through movement. Physical education is an important part during these developmental years. Children are able to run and jump as well as having control of large muscles in their legs. The body and mind rarely work together. They have a difficult time holding small things, catching or putting something together using their fingers. The total number of students in this lesson plan classroom is thirty. The school is Mary L. Fonseca Elementary. There will be some fundamental skills that we will try to teach the elementary students; for example jumping and landing. Locomotors skills we will teach them skipping, running, sliding, galloping, leaping, hopping, and non- locomotors skills students we will teach twisting. The student objective goals would be that the end of the course students will successfully jump and land on balance in different ways. The students successfully improve their distance as well as height....

...Jennifer Czachura 3/27/07 Critical Thinking Essay Kim Groninga “I’m Nobody! Who are you?” by Emily Dickinson Most people feel invisible at some point in their lives; whether it’s because they’re in the shadow of an older sibling, because they are shy, or simply because everyone around them has been busy, it doesn’t make much difference. It’s still a horrible thing to feel like no one even realizes you’re alive or that you’ve been doing things. Emily Dickinson felt this way often; she lived at home and didn’t leave the house much, mostly corresponding with people by letters. However, her invisibility didn’t bother her too much, and that is what this poem is all about. When you feel invisible, you aren’t alone, because someone else is feeling invisible too. Dickinson starts out the poem introducing herself, ”I’m Nobody! Who are you?” (1) Being nobody can mean a lot of things; it could mean she’s no one important, no one special, no one significant, or no one that everyone knows. However, she could also be nobody to many people simply because she doesn’t try to stand out or feel important. She is content just being herself, living her plain, simple life and doing things that make her happy. Being nobody makes her somewhat mysterious; she’s obviously a person, but most people don’t know who she really is. This also relates to the second line in the poem, “Are you – Nobody – too?” (2) Dickinson’s question of the reader seems to show tha t being nobody is something everyone feels at...

...Edwards Frogs vs. Toads Most people find it difficult to differentiate a frog from a toad. They normally mix them up. Although they seem similar in a lot of areas, they certainly have numerous dissimilarities too. Frogs are found in many different shapes, sizes, and colors. Frogs have smooth, wet skin. They live most of the time in or near water. They have different eye colors including brown, silver, green, and even red along with different shapes and sizes. Some of the frogs have sticky feet while some are webbed. It is obvious that not even all frogs have same qualities. Toads too have numerous shapes, sizes, and textures, but they don’t have much variety in color. Toads are fat and have rough skin. They do spend most of their time in water, but they live in moist places like woods, fields, and even gardens. Their pupils do have different shapes, sizes, and colors, but generally they are egg-shaped, small and black. They also have webbed feet. Toads and frogs have the same way to catch and eat food. Both of them use their tongue to catch prey. But a frog has a very small tooth around its upper jaw edge to capture food, but a toad doesn’t have any teeth at all. Toads eat almost the same foods as frogs like bugs, insects, fish, etc. In Conclusion, frogs and toads do seem similar but they have several qualities regarding shape, size, color, and texture that make them different. So it should be crystal clear that people can mistake the difference between a frog and a...

...weekdays to support the family. We would paddle to the middle of the lake, singing ‘row, row, row your boat, gently down the stream’ like little kids. When we reached the centre of the lake, we would stay as quiet as possible, so we wouldn’t scare the fish away. If we were lucky, we would make a nice catch for dinner, but we weren’t always so lucky. The lake was always peaceful. Its surface was so calm and still that it could have been a mirror. I would dip my finger into the water, making little ripples that would cascade across the surface creating an image as though the mirror was flexing and going to shatter. Fishing wasn’t the most exciting experience, sitting there for hours. The only excitement would have been to see one of those tiny frogs leap out of the shallow end of the still lake, hop around on the bank, until eventually they would disappear into the tall grass of the adjoining forest. Not that I was particularly fond of their appearance, but they did provide some entertainment. That particular Sunday was no different. We went fishing at the same old lake. We paddled out to the centre and sat with our fishing rods just lazily hanging over the edge of our ageing canoe. As I was staring into the distance, with the recurring hope that I will finally feel the tug of a fish being hooked on the end of my line, I felt a light jerk coming from the forward bow of the canoe. From the corner of...
