The science behind each concept is explained using animations related to DNA topics, an image gallery, video interviews, problems, biographies, and links related to DNA. There are three sections, Classical Genetics, Molecules of Genetics and Organization of Genetic Material. Key features are the clear explanations of classical experiments and the excellent photographs of researchers and their labs.For information and credits on the development of DNA from the Beginning, go to http://www.dnaftb.org/dnaftb/credits.html http://www.merlot.org/merlot/viewMaterial.htm?id=89055 Here's your chance to mix chemicals without wearing safety goggles. You won't spill any acid on the spectrometer in this lab. Choose solutions from the vast database and mix 'em together till the cloned cows come home. Marvel as the chemical solutions react in real time. http://www.merlot.org/merlot/viewMaterial.htm?id=80654 A collection of simulations and virtual labs focusing on first-year college physics. An interview with the award winning author can be found in About us at Phet VideoPhET provides fun, interactive, research-based simulations of physical phenomena for free. We believe that our research-based approach- incorporating findings from prior research and our own testing- enables students to make connections between real-life phenomena and the underlying science, deepening their understanding and appreciation of the physical world. To help students visually comprehend concepts, PhET simulations animate what is invisible to the eye through the use of graphics and intuitive controls such as click-and-drag manipulation, sliders and radio buttons. In order to further encourage quantitative exploration, the simulations also offer measurement instruments including rulers, stop-watches, voltmeters and thermometers. As the user manipulates these interactive tools, responses are immediately animated thus effectively illustrating cause-and-effect relationships as well as multiple linked representations (motion of the objects, graphs, number readouts, etc.) PhET Interactive Simulations, University of Colorado, http://phet.colorado.edu http://www.merlot.org/merlot/viewMaterial.htm?id=83322 VR Molecules presents dynamically and interactively the vibration and rotation modes for 24 molecules (out of a more extensive list) containing up to twelve atoms. It allows the user to create and save on his or her hard disk documents containing, much in the same way as Power Point presentations, up to 10 "pages״, each featuring one or two molecules with specific parameters (viewpoint, active modes, etc.). These presentations can be made available through the Internet, with optional sound and text explanations associated with each page.The latest, augmented version of VR Molecules, called VR Molecules Pro 1.1, is available online as well as in a stand-alone version (Mac and Windows).To view a video of the award winning author, go to View VR Molecules - Chemistry Award Winner 2007 video VR Molécules est un logiciel de simulation (en ligne et en mode local) permettant de visualiser et d'explorer les modes de vibration et de rotation des molécules (24 molécules sont disponibles).Il peut tout aussi bien être utilisé par le professeur pour préparer des démonstrations en classe, intégrer des animations (interactives ou non) dans ses documents HTML, que par les étudiants pour revoir les démonstrations présentées en classe et explorer par eux-mêmes la vibration et la rotation des molécules.La plus récente version (1.12) de VR Molécules, est accessible en deux versions : en ligne et en mode local (à télécharger, pour Mac et Windows). http://www.merlot.org/merlot/viewMaterial.htm?id=88586 An effective tool to help students learn about all aspects of the ideal gas law. One of the best web gas law simulations. http://www.merlot.org/merlot/viewMaterial.htm?id=90727 This interactive site allows participants to learn about skeletal anatomy by viewing the bones of a human, chimpanzee, and baboon. Users select a bone from the list of four bone types on the skeletal image, and launch the bone viewer. A detailed look at each bone from six viewing angle options is provided along with the option to select another bone or make a comparison with another species (chimpanzee or baboon). The Comparative Anatomy section enables users to make direct comparisons of bones. The material is appropriate for science teacher education as it illustrates how careful observation leads one to wonder about the dizzying beauty of a planet that works by bringing us one different creature after another. http://www.merlot.org/merlot/viewMaterial.htm?id=85084 The site is an interactive game.The game shows a variety of people involved in halting an outbreak and only the intern can save them! The players receive case files, maps, visit locations, take samples and draw conclusions. Players not only try to solve the case, but learn about public health careers.A teachers guide and related links are included.Key words: Public Health, Epidemiology,case study, health sciences careers.

Then, they play the role of biologist, analyzing the changing gene frequencies of the moth population and determining if the population evolved over three generations. Students will: 1) collect data by eating moths; 2) calculate gene frequencies for each phenotype over three generations; 3) interpret graphs of data their data to determine if microevolution occurred; and 4) explain how selection acts on populations.To view a video of the award winning author, go to View Connecting Concepts - Biology Award Winner 2008 video The authors also participated in the MERLOT Classics Series on Elluminate: " target=״_blank״>https://sas.elluminate.com/site/external/jwsdetect/playback.jnlp?psid=2010-03-31.1707.M.9E9FE58134BE68C3B413F24B3586CF.vcr http://www.merlot.org/merlot/viewMaterial.htm?id=404555 This is exactly what it says...a periodic table that comes alive. For each element that you click on, it'll give the name, picture, history, and everylittle thing you'll need to know about that element. It even has a media section to veiw different forms, images, and videos of that particular element.
