Covers the concept of ratios and proportions, the correct way to express and write ratios and proportions, ratios and proportions in their simplest form, and comparing ratios and proportions. Provides real-life situations in which ratios and proportions would be applied, such as mixing paint, reading and interpreting map scales, and calculating map distances.

The ancient city of Rome wasn't built in a day, but now that city, along with all its famous landmarks, can be digitized in just a matter of hours. A new computer program under development at the University of Washington in Seattle combs through hundreds of thousands of tourist photos on Flickr and other photo sharing sites and reconstructs the city – pixel by pixel. Now, viewers can fly around many of Rome's famous landmarks on their computer in far more detail than they'd ever be able to on current virtual map programs such as Google Earth. The new technique may one day create online maps that offer viewers a virtual-reality experience. The software could build cities for video games automatically, instead of doing so by hand.
This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans. The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.
Host Peter Tonge visits the Weston Maple Sugar Project in Weston, Massachusetts. Shows the process of making maple syrup from tapping a maple sugar tree to boiling sap in a sugar shack. The second part of the program focuses on the basics of planning a garden in late winter. Also explains how to mix and apply liquid fertilizers. Originally aired as an episode of "The Good Green Earth."
Divers in Florida explore a labyrinth of treacherous caves as they attempt to map the state’s freshwater resources. Segment of video from Wild Chronicles Series.

Hurricane Sandy was the deadliest of the 2012 hurricane season and was the second costliest hurricane in U.S. history. University of Washington civil engineer Dorothy Reed and her team received a grant from the National Science Foundation to study how Hurricane Sandy affected the infrastructure of the New York Metropolitan area, including the power and transit systems. Reed and her team area creating highly detailed maps to construct a comprehensive street-by-street view of Sandy’s devastation.
Neuroanatomist Jacopo Annese is looking for 1,000 brains. The Director of the Brain Observatory at the University of California, San Diego is on a quest to collect, dissect, and digitize images of the human brain for the Digital Brain Library, which was launched with support from the National Science Foundation. Annese and his team look for connections, mapping brain structure and connecting it to human behavior. He believes that with a large enough catalog of brains preserved as virtual models, scientists can explore the organ in ways unheard of, revealing new insights into what makes the brain tick.
Imagine a virtual computer simulation that reflects the world in real-time. The current virtual reality technology center has been creating and implementing this technology at the University of Southern California campus in Los Angeles. It is called Geo-Immersion. Center director Cyrus Shahabi envisions the technology being used at other college campuses and institutions for applications ranging from social networking to enhancing security.
David Ray never turns his back on his research, and with good reason. Ray and his team study alligators, crocodiles, and bats. With support from the National Science Foundation, this multidisciplinary team from several universities is mapping crocodile and alligator genomes. Reptiles resembling these have existed for around 80 million years and they are among the first reptiles to have their DNA sequenced. The research will expand knowledge beyond crocodilians to other reptiles, birds, and even dinosaurs.
As shown on the History Channel. We are so familiar with the map of United States, but do we know why our states look the way they do? Every shape on the map tells a story about our past. Why is California bent? To cling on to gold. Why does Oklahoma have a panhandle? Because of shifting borders for slavery. Why does Missouri have a boot? Because of a massive earthquake. Examines how every state is a puzzle piece revealing the unique geography, political, and social history of America.
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).
In this episode, groups of citizen scientists use apps and maps to help researchers gather data about medical conditions. Sensors on asthma inhalers generate real-time maps of environmental dangers to help patients and physicians in Louisville, Kentucky. In West Oakland, California, citizens confront air pollution and rising asthma rates by collecting traffic data. Citizen scientists are fighting mosquito-borne diseases with apps and crowd-sourced data in Barcelona, Houston, and New Orleans. Part of "The Crowd and the Cloud" series.
In this episode, host Emily Graslie discusses the pangolin or "scaly anteater." They are typically found in Africa and covered in an armor to protect them from predators. Part of "The Brain Scoop" series.
Journey through the marine ecosystem of Monterey Bay, California, where a giant kelp forest hosts one of the most diverse marine ecologies in the world. The secret to the balance of this ecosystem is a keystone species: the sea otter. Part of the "Nature's Microworlds" series.
When a tsunami hits, it may come ashore like a fast rising flood and strike with devastating force. The series of waves may continue for hours. Sometimes the first one may not be the last or the largest. Potential warning signs of an incoming tsunami include a strong earthquake that causes difficulty standing, a rapid rise or fall of the water along the coast, and a loud ocean roar. Part of the "Danger Zone" series.
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 Wanda discovers that one of Ms. Frizzle's ancestors was Redbeard the Pirate, she naturally wants to follow the treasure map he left. The map leads the class to a coral reef, where they learn firsthand that life there is risky. To survive, they find, many plants and animals form surprising partnerships.
Take a tour of the moon's surface. Images and topographic maps show craters, rocks, mountains, basins, and valleys found on the moon. These maps help improve scientific understanding of how Earth's moon and other rocky planets in the solar system evolved.
Observe changes to electrostatic force as you play with the distance between charges and charge amounts at both macro and atomic scales.
