7:00 video: This film is the first of a two part series on the evolution of new genetic information. Here we focus on Point Mutations - the simplest natural mechanisms known to increase the genetic information of a population. Our second film of the series will focus on duplication events - natural mutations that increase the total amount of genetic information of an individual. This film was produced under the guidance of molecular biologist Dr. Nicholas Casewell. http://www.lstmed.ac.uk/about/people/... Point mutations are small, natural edits in the DNA code of an individual. These edits can be passed from parent to child. Because they are mere edits, point mutations usually do not increase the total amount of information in an individual. As new information is gained, old information is lost. Point mutations do, however, increase the total amount of information within a population. In this film you will see several examples of beneficial point mutations which have enhanced a creatures abilities or even given rise to entirely new abilities. The first two examples were directly observed in bacteria by scientists in the lab. The third is a case found in domestic dogs, the last example was discovered in several species of wild animal.

Over the years, many teachers have told us that these films seen on NATURAL HEROES offer a valuable resource for the classroom. To help more teachers and students take advantage of the rich content of these timely stories, we have developed a 46-page classroom guide consisting of 6 projects aligned to common core to accompany these films. We also have included interactive links to additional resources and short video selections from the films to use with your students.

Gene Screen BC 2011 Participant. 18 Things You Should Know About Genetics is an animated film that presents fundamental background information about genetics, as well as offering some quirky but interesting facts about DNA, genes and genetics. It was created to be an upbeat, fun educational short film to initiate and draw interest to this sometimes daunting and seemingly complex subject matter.

In the second film of the Great Transitions trilogy, paleontologist Julia Clarke takes us on a journey to uncover the evidence that birds descended from dinosaurs. The discovery of Archaeopteryx in a quarry in Germany in the early 1860s provided the first clue that birds descended from reptiles. But what kind of reptile? In the last 40 years, scientists have identified many shared features between birds and two-legged carnivorous dinosaurs called theropods. The film illustrates many of the practices of science, including asking important questions, formulating and testing hypotheses, analyzing and interpreting evidence, and revising explanations as new evidence becomes available.

The short film opens with two questions: "So what determines how many species live in a given place? Or how many individuals of the species can live somewhere?" The research that provided answers to these questions was set in motion by key experiments by ecologists Robert Paine and James Estes. Robert Paine's starfish exclusion experiments on the coast of Washington state showed that removing starfish from this marine ecosystem has a big impact on the population sizes of other species, establishing the starfish as a keystone species. James Estes and colleague John Palmisano discovered that the kelp forest ecosystems of the North Pacific are regulated by the presence or absence of sea otters, which feed on sea urchins that consume kelp. These direct and indirect effects of sea otters on other species describe a trophic cascade. These early studies were the inspiration for hundreds of investigations on other keystone species and trophic cascades, as well as ongoing studies into the regulation of population sizes and species numbers.

In the deep, dark ocean, many sea creatures make their own light for hunting, mating and self-defense. Bioluminescence expert Edith Widder was one of the first to film this glimmering world. At TED2011, she brings some of her glowing friends onstage, and shows more astonishing footage of glowing undersea life.

In the past, sailors on whaling ships would carve whale teeth into works of art in a process called scrimshaw. These pieces would be brought home to loved ones as mementos of the voyage. Design incubator Studio Swine is attempting to recycle found materials and turn this aged art form into a more sustainable practice. In this short film, travel to remote parts of the ocean, where "the closest people are in a space station," and watch as the process of collecting ocean trash and transforming it into beautiful treasure unfolds.

Most 12-year-olds love playing videogames -- Thomas Suarez taught himself how to create them. After developing iPhone apps like "Bustin Jeiber," a whack-a-mole game, he is now using his skills to help other kids become developers. (Filmed at TEDxManhattanBeach.)

How does a Killer T Cell Kill its target? Our new film captures the behaviour of cytotoxic T cells - the body's 'serial killers' - as they hunt down and eliminate cancer cells before moving on to their next target.

Amanda Briody describes two BioInteractive resources focused on Gorongosa National Park in Mozambique. She uses the short film "The Guide: A Biologist in Gorongosa" to introduce students to the park and its scientists. The Gorongosa Interactive Timeline allows her to ask data-based questions on the park's history and ecology, and have students make evidence-based claims.

Australian outfit Bridge 8, who have the admirable mission of devising "creative strategies for science and society," and animator James Hutson have created six fantastic two-minute animations on various aspects of critical thinking, aimed at school ages 8 to 10, or kids between the ages of 13 and 15, but also designed to resonate with grown-ups. Inspired by the animation style of the 1950s, most recognizably Saul Bass, the films are designed to promote a set of educational resources on critical thinking by TechNYou, an emerging technologies public information project funded by the Australian government.

9:14 video Have you ever wondered how life first got started on Earth? So do scientists! Though the question has not yet been fully answered, a careful study of Chemical Evolution is beginning to shed light on this mystery. In this film you will learn what Chemical Evolution is, how it works, and how it is different from Biological Evolution.

Why is their so much secrecy in animal research? Can't we do without animals in medical research? In this video Dr Simon Festing, our ex-Chief Executive, answers questions about why animals are an essential part of medical work. Download this film here: http://ww

This activity supports the HHMI short film The Origin of Species: The Making of a Theory. Students are presented with a map of the Malay Archipelago and some field notebooks with observations of animals. By plotting which animals are found on which island, the students discover the Wallace Line-a sharp boundary that separates distinct Asian and Australian fauna. 

This hands-on activity, used in conjunction with the film The Making of the Fittest: Natural Selection in Humans, teaches students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. It uses simple simulations to illustrate these complex concepts and includes exercises such as calculating allele and genotype frequencies, graphing and interpretation of data, and designing experiments to reinforce key concepts in population genetics.

This activity can be used in conjunction with the short film The Double Helix. It introduces students to the classic experiment by Matthew Meselson and Franklin Stahl, which revealed that DNA replication follows the semiconservative model.

When watermen find wounded fish along a lonely river in Maryland, they kick off a scientific debate and an environmental crisis focused on a mysterious microbe that may -- or may not -- cause sick fish and sick people. Watch the title sequence from this award-winning, hour-long film.

This groundbreaking NRDC documentary explores the startling phenomenon of ocean acidification, which may soon challenge marine life on a scale not seen for tens of millions of years. The film, featuring Sigourney Weaver, originally aired on Discovery Planet Green.
