The authors cite some researches and say that if we understand the three important cognitive tools of story structuring, binary opposites and forming images from words, we could better design our curriculum and could make learning enjoyable and fun.
The article picks up a very important subject and one that should be shown to every single teacher in the world. Teachers who often find students disruptive or slow because they are not showing interest in class lessons can benefit from learning about reluctant learners and the ways this issue can be handled. Every student deserves a chance to explore his world and since their imagination is very fertile, they need their teacher's assistance to learn through their own imaginative tools and in their own way.
If the teacher is aware of the three tools, he or she can better provide that assistance and allow the child to learn at his own pace…...

The following is a brief overview of the biological classification, diet, distribution and social behavior of the mammalian orcinus orca. The research also outlines the factors that are responsible for the decline in orcinus orca population around the world today. Special emphasis has been given to resident orcinus orca to demystify the concept that orcas are lethal to the fishermen and hence should be targeted for hunting.
Orcinus orca, commonly known as the killer whale, is a top predator marine mammal. Orcas are very social animals and live in pods. During the past 30 years extensive research has been conducted for the species regarding behavioral ecology, genetics, population monitoring, behavioral studies and acoustic research. Much of that research has been dedicated to the study of resident orcas. In recent years there has been a sharp decline in the numbers of resident orcas. In the following…...
Beluga Whales of St. Lawrence Estuary
Lawrence iver estuary, located in Quebec, Canada, has long been home to the southernmost population of beluga whales, and this isolated population of marine mammals has encountered continual pressure from external sources, such as overhunting and pollution, for most of the 20th century. Although a comprehensive ban on whaling was instituted in the 1950's, marine biologists and other researchers have noted that the expected beluga whale population recovery has failed to materialize, and a number of sound theories have been put forth by qualified scientists to explain the phenomenon. One of the most widely read and recognized of these hypotheses was developed by Canadian researcher Daniel Martineau and a team of colleagues, who studied the corpses of over a hundred beluga during a period of 17 years before determining that the St. Lawrence iver estuary "beluga and their environment are contaminated by polycyclic aromatic hydrocarbons…...

The Narwhal or monodon monoceros is a rarely seen arctic whale. Its name is derived from the Norse, meaning 'corpse whale' due to its grayish appearance while floating in the water. (American Zoo) Narwhal whale's are described as having 'small rounded heads, short flippers with upturned tips, and no dorsal fin but an uneven dorsal ridge along the spine'. (Whale guide Reference Desk: Narwhals) The males are larger than the females and the largest of the species measures 16 feet or 4.9 meters on average and weigh 1.8 tons (1.6 tonnes). At birth a Narwhal usually measures about 5 feet (1.5 m) in length and weighs 175 pounds (80 kg). (All about Whales) The color of adult Narwhals is mottled grey but the older Narwhals are generally pure white.
Narwhal whales are usually located in the arctic seas at the latitudes of 700 North and 800 North. . They…...
Acoustic Properties of Humpback Whale Songs
Sound production and detection are critical to the lives of marine organisms. Organisms including mysticetes or baleen whales use sound as their primary means of learning about their environment and also as means of communicating, navigating and foraging for food (NC, 2003). Consequently, there is a growing concern that sounds produced by humans (anthropogenic sounds) may interfere with these essential activities by polluting the waters with sounds that could potentially injure the hearing organs of these mammals. In a report issued by The National esearch Council in 2003, the council identified a number of critical objectives for future research on ocean noise and marine mammals. One of these recommendations urged research teams to "describe the distribution and characteristics of sounds generated by marine mammals & #8230;within behavioral contexts" (NC, 2003, 128). Au et al. (2006) sought to achieve this objective in a study that examined…...

Measurements were obtained both in the presence of and the absence of whale watching boats. It was observed that a period of intense boating activity caused the killer whales to adjust their call duration levels to compensate for the background noise. This clearly indicates that anthropogenic noise levels directly interfere with the routine life of the killer whales, which are dependent on vocal communication for successful hunting and survival. [Andrew et.al. 2004]
It is well-known that anthropogenic sounds can even have fatal consequences as evidenced by the recent mass strandings of beaked whales that coincided with the mid frequency sonar exercises by the navy. A recent research by (Holt et.al, 2009) focused on the effects of anthropogenic sounds on the vocal behavior of killer whales.

The plan would be the result of the scientific method, through which the impacts and causes of the current environmental problems would be addressed. Additionally, the scientific method would sit at the basis of the future actions to be taken. These would traditionally include:
The search for alternative sources of energy
The search for renewable sources of energy
The creation of an infrastructure which allowed the propagation and populous use of alternative energies
The education of the population to reduce their levels of consumerism to life necessities
The implementation of stricter regulations which punish economic agents who pollute waters or cut the forests in an unsustainable manner
eplant forests, clean waters and support the sustainable life of the endangered species.
At a smaller size and specific level, the alternative and immediate action to be taken is that of reducing the harvesting of krill by commercial fishermen. This would be achieved through legislative means which forbade the harvesting…...

The Delta is also a habitat for many species of fish, birds, mammals, and plants, and it supports agricultural and recreational activities while also being the focal point for water distribution throughout the State.
The development of the Delta as it exists today started in late 1850 when the Swamp and Overflow Land Act transferred ownership of all swamp and overflow land, including Delta marshes, from the federal government to the State of California. In 1861, the State Legislature created the Board of Swamp and Overflowed Land Commissioners to manage reclamation projects, and in 1866, the authority of the Board was transferred to county boards of supervisors. The Delta now covers 738,000 acres interlaced with hundreds of miles of waterways, with much of the land below sea level, relying on more than 1,000 miles of levees for protection against flooding. 20

International egulation of Tourism in Antarctica
Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how to administer regulations pertaining to the preservation of life forms on the continent, what those regulations should be, and what sanctions should be applied and by whom.
To understand the depths of the negotiations, and the potential for discord, it is necessary to understand what the continent offer the 65% of global nations that are party to the 1959 and all subsequent treaties. To understand the possible future of Antarctica, it is necessary to outline treaty attempts to minimize commercial interests…...

What's Happening With the Blue Whale
The Blue Whale is the largest mammal to live on earth. If the blue whale lived on the land, the weight of its immense body and bones would crush it. They can weigh up to 200,000 pounds and the biggest ones can be 100 feet long. That's one-third the size of a football field, and longer than three school buses! The blue whale is part of the rorqual whale family that includes the humpback whale, fin whale, Bryde's whale, sei whale, and minke whale. These whales all have large pleats on their throats that let them expand when they swallow water.
The Blue Whale has a long body with a flat, broad head. It has a long, pointy mouth and chin, and small fins attached partway down its…...
Blackfish: The Documentary That Exposes SeaWorld
Abstract
When the documentary, Blackfish was released in 2013, SeaWorld officials initially responded by blaming falling attendance on negative media attention, but the falloff in attendance on the part of the general public confirmed that there was widespread outrage over the conditions in which orca whales were maintained. The documentary focused on Tilikim, a wild-caught orca whale that was subjected to medieval conditions that caused him to turn on his human trainers and kill several. This essayprovides an analysis concerning the decline in attendance at SeaWorld following the Blackfish documentary release and a discussion concerning SeaWorlds announced plans to discontinue their orca whale captive breeding program, followed by a personal reaction to this important but disturbing documentary.

In the fall, they migrate from the summer feeding grounds, heading south along the coast of North America to Mexico, to the calving and nesting waters of the Sea of Cortez, where they seek shelter and the calmer waters of Scammon's Lagoon, at Baja, California. Calves are born in the shallow lagoons and bays from early January to mid February. Then the north bound journey begins in mid February to May, the Eastern North Pacific stock of gray whales can be seen migrating with newborn calves along the west coast of America. The new born calves have a pebbly appearance, like a slate gray 'dill pickle" -- this is an easy visual to identify them. Thanks to the whalewatch industry, that began in the 1970's, this is one of the best documented whale species on earth.

Region of Megalopolis (urban area in Northern America) and its sub-Region of Nantucket (off Cape Cod)
This paper describes the geographic region of Megalopolis (urban area in Northern America) and its sub-region of Nantucket (off Cape Cod). It also deals with the history of Nantucket and the causes that led to the formation of the megalopolis in northeastern USA. Megalopolis comes from the Greek words for 'very large' (Mega) and city (polis). It basically means a very large city. Jean Gottmann, a Frenchman, coined this term to refer to northeastern USA extending from oston to Washington DC. The idea of Megalopolis existed in Ancient Greece where they attempted to create a very large city in the Peloponnese Peninsula. Their attempt was unsuccessful but the small city of Megalopolis that they created still exists. The concept of Megalopolis lies in the fact that cities are not viewed as individual units but as…...

The decline in whale hunting practices over the centuries is a testament to the evolving societal values and the increasing recognition of the importance of marine ecosystem preservation.
## Elaboration
The practice of whale hunting has undergone significant transformations throughout history, influenced by factors such as technological advancements, economic drivers, and shifting societal attitudes. In the early stages, whale hunting played a crucial role in meeting human needs for food, oil, and other resources. However, as time progressed and alternative sources of these commodities became available, along with growing awareness of the ecological repercussions, whale hunting practices gradually declined.

When it comes to the largest shark species, one name reigns supreme: the colossal Megalodon. This prehistoric behemoth roamed the oceans approximately 23 million to 2.6 million years ago and remains the largest shark, and indeed, the largest fish, to have ever existed.
Size and Appearance
The sheer size of the Megalodon was awe-inspiring. Scientists estimate its maximum length at around 18 meters (59 feet), roughly the size of a school bus. Its weight could reach a staggering 60,000 kilograms (132,000 pounds), making it heavier than a Bulldozer.
The Megalodon's appearance was equally imposing. Its massive....
Just like in humans, marine species exhibit a remarkable diversity in their behavior and personalities, showcasing their individuality beyond their physical characteristics. These unique traits influence their social interactions, foraging strategies, and overall survival. Here's an exploration of how different marine organisms display distinctive personality traits:
1. Fish:
boldness/shyness: Bold fish are more likely to explore novel environments and take risks, while shy fish tend to be more cautious and avoid unfamiliar situations. aggression/submissiveness: Aggressive fish actively defend their territory and resources, while submissive fish prefer to retreat from conflict. curiosity/explorative: Curious fish are driven to....
