The parakeet starts without a script because Boronitas, the screenwriter, is sick. Amanda decides to improvise and presents the guest: the rabbit, who failed the school year because the llama failed to turn in an assignment. When the llama arrives with the script, they tell her it's already late and complain about her lack of responsibility. She explains that she took too many jobs at a time and failed to comply. Then Eva and Maite say they don't understand why humans say yes to everything, even bad things like smoking, drinking, and others. the celebrity guest, Maradona former soccer player, who said no to food. At the end the parakeet explains the importance of learning to say no.

Puppies are a joy to behold, but with that joy comes responsibility. Regardless of what kind of puppy one has, the same general rules apply when caring for a pet. Like people, all puppies have different personalities, and no two are exactly the same. For this reason, owners of new puppies or dogs will have to take time to get to know them, to build trust, and to discover what actually motivates them. Experts explain all the necessary steps to ensure that a puppy grows up to become a healthy, well-behaved, and much-loved addition to a family. NOTE: Bonus material follows main feature.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
A boy takes his two pets-a dog and a frog-to the park. While the boy is busy chasing his dog, the frog takes the opportunity to hop out of its basket and explore. Its first adventure is a ride in a toy truck that's being pulled by a little girl. The boy and dog hunt for the frog. Meanwhile, the frog joins the act of a street magician, hides in a picnic basket, takes a ride in a toy motorboat, and jumps into a baby's carriage. The baby's mother summons the park police, but the boy and dog rescue their amphibian friend just in time. Based on a book by Mercer Mayer.
New research led by scientists at the University of California, Berkeley, suggests that the shape of some animals' pupils could reveal whether one is hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads.
The second in a series of documentaries is built around a custom that is thousands of years old: fishing. At present, about 65 million people in the Greater Mekong live directly from the fish the river has to offer. Fishing methods are of course different according to places and ethnic groups. Additionally, modern times strongly challenge the fishermen in the Greater Mekong. Torn between tradition and modernity, these men and women have to make for themselves, and their families, decisions about new ways of life. Climate change and pollution add to the problem of a painful adaptation to a new way of life. Series: The Soul of Southeast Asia
Scientist William Rowan is renowned for his research on the dark-eyed junco. Before Rowan, it was unknown what environmental cues animals used to time the seasonal changes in their biology. Through a groundbreaking experiment with the junco, Rowan discovered the physiological reaction of organisms to the length of day or night. Shot as an historical re-enactment, this segment provides a glimpse into the history and human dimensions of scientific research and reveals one of the first studies that made juncos well-known to biologists. Part of Ordinary Extraordinary Junco (Chapter 1).
In the dark recesses of a warehouse, a drunken game of cards explodes into a murder. Now the night watchman lays dead. The only witnesses are a housefly or perhaps a cockroach that might be skittering by. That stylized tribute to our seemingly endless appetite for TV programs about forensic science sets the stage for an examination of how, in the real world of police investigations, nature is being enlisted in the war on crime. Sifts through the mayhem, murder, and science that make up the world of forensic investigation with the help of Dr. Jennifer Gardy, of British Columbia's Centre for Disease Control (CDC).
Throughout North America, the species known as the dark-eyed junco exhibits striking differences in feather color, body size, and behavior from place to place. These variations among subspecies have caught the attention of biologists interested in diversification, evolution, and speciation. This segment features footage from junco habitats across the continent as researchers try to decode the riddle of the Junco’s evolutionary history. Part of Ordinary Extraordinary Junco (Chapter 3).
Leaf cutter ants could be called the overachievers of the insect world. They are farmers, medicine makers, and green energy producers. With support from the National Science Foundation, bacteriologist Cameron Currie studies the complex evolutionary relationships between the ants, the fungi they cultivate and eat, and the bacteria that influence this symbiosis. At the University of Wisconsin-Madison, Currie works with the Great Lakes Bioenergy Research Center on campus to explore how the ants manage to degrade cellulose. Her goal is to discover new ways humans might break down biomass into biofuels. The bacteria component of the ant colony could also help scientists develop more effective antibiotics for human health and agriculture.
The Mexican free-tailed bat is one of the most abundant mammals in North America. Outside of San Antonio, Texas there is a cave that is home to over 40 million of these bats. Roosting in large numbers in relatively few areas makes them especially vulnerable to human disturbance and habitat destruction. Documented declines at some roosts are cause for concern because there is a delicate balance in the ecosystem that depends on the bats. There is also cause for concern among other bat species that are falling victim to white nose syndrome, which is a condition named for a distinctive fungal growth around the muzzles and on the wings of affected animals.
One of the oldest, most successful arthropods on Earth, horseshoe crabs have existed for over 350 million years. But in recent years their populations, have crashed by 75% from overfishing, resulting in moratoriums on catching them. Few of us know that most human lives depend on the valuable, shockingly blue blood of these "living fossils." Even more surprising, a tiny shore bird, the red knot, is so dependent on them that the crabs' population crash may make these long-distance flyers extinct. This mystery of mutual dependencies emerges from filmmakers and scientists revealing a disturbing ecology story ranging from the Arctic regions to the southern tip of the Americas.
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.
The rock pocket mouse is a living example of Darwin’s process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you’re a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. The film features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. In a complete story, from ecosystem to molecules, pocket mice show us how random changes in the genome can take many paths to the same adaptation—a colored coat that hides them from predators.
University of Pennsylvania ecologist Peter Petraitis, California State Northridge biologist Steve Dudgeon, and their team have been returning to Maine’s rocky intertidal zone every spring and summer for nearly two decades. With support from the National Science Foundation (NSF), they survey a network of 60 experimental plots. The big question that brings them back year after year: Is an ecosystem like this a stable and permanent fixture, or, under harsh conditions, could it reach a tipping point? The idea is that changes in conditions could cause a switch from one community to another, such as from mussel beds to rockweed, and then back again.

We often hear about insects and other animals passing on diseases to humans, so-called zoonotic diseases, such as rabies, cholera, and West Nile virus. Now, for the first time, researchers are examining a disease that humans are spreading to an animal, specifically Elkhorn coral off the Florida Keys. With support from the National Science Foundation, Rollins College biologist Kathryn Sutherland is tracing this emerging infectious disease phenomenon, known as “reverse zoonosis.” Elkhorn coral was once the most common coral in the Caribbean, but it's now a threatened species due to population losses from White pox disease. Sutherland believes undertreated sewage, possibly from leaking septic tanks or illegal cruise ship discharge, could be the source of this disease.
A bored parakeet begins his monologue talking about the upcoming carnival. All the animals on the show are organizing the carnival. Amanda, as usual, will not let him finish and comes out dancing in her carnival skirt. For her, the carnival is the ultimate event. The guest dog is opposed to having the carnival. The sloth enters and tells the truth. The dog likes the carnival, but he likes it so much and gets so excited that he has to go to the bathroom. Maite and Eve talk about different ways of expressing joy. The celebrity guest, soccer player Asprilla, explains he celebrated his goals with firecrackers. Everyone would get scared, and the game would be suspended. So he changed his way of celebrating and now does somersaults.
The seemingly peaceful atmosphere in an organic garden on the University of Florida campus belies the battles happening among many of its tiniest inhabitants: the insects. For entomologist Christine Miller, there are endless opportunities here to study how insects compete and even fight for a mate. With support from the National Science Foundation, Miller and her team are researching mate selection and animal weapons as a key to better understanding animal behavior, diversity, and evolution. Understanding evolution is essential for figuring out solutions to modern problems such as antibiotic resistance, a major problem in medicine, and for understanding how life on the planet became so diverse and how it may change in the future.

The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. When the principal, Mr. Ruhle, has to go away for a few days, he leaves his beloved chicken, Giblets, in Dorothy Ann's (DA) care. Unfortunately, the minute Mr. Ruhle is out the door, Giblets flies away, and DA sets out to find a replacement for Giblets. The next thing DA knows, Ms. Frizzle and the class are on a field trip to see how eggs are made — from the inside out.
