Classical vs. Transgenic Breeding
This video segment from FRONTLINE/NOVA: "Harvest of Fear" discusses the genetic consequences of both classical (traditional) breeding and genetic engineering of crop plants. While classical breeding combines thousands of genes between individuals of the same species, genetic engineering combines one or a few selected genes between individuals of the same -- or, in some cases, different -- species. Closed captioning included. Run time 03:11.
Biologist Robert Full shares slo-mo video of some captivating critters. Take a closer look at the spiny legs that allow cockroaches to scuttle across mesh and the nanobristle-packed feet that let geckos to run straight up walls. Robert Full studies cockroach legs and gecko feet. His research is helping build the perfect "distributed foot" for tomorrow's robots, based on evolution's ancient engineering. Run time 19:28.
The Life of a Tree
In this interactive activity adapted from the National Arbor Day Foundation, explore the intricate life of a tree. The trunk of a tree functions as both a supporting structure and a pathway, transporting food down from the photosynthesizing leaves and conducting water and minerals up from the roots. Look inside a tree to learn about the xylem, cambium, and phloem, and to see how the tree's rings provide a record of the environmental factors that affected its growth and life cycle.
In this video from WPSU’s Outside, a staff member at Shaver’s Creek Environmental Center at Penn State University provides tips on backyard bird feeding during the winter. Topics include the selection, placement, and cleaning of feeders. To attract birds for viewing, and to contribute to their welfare, it is important to understand their needs and behaviors. Placing a bird feeder close to a window will prevent collisions with glass. Offering seeds and suet can provide birds with the energy t
Ecologists snatch and band pelican chicks so they can monitor the pelican colony's health in this movie. The short video clip discusses how the pelican population is struggling because their natural habitat is disappearing and other environmental issues. The video could also be used with a lesson about endangered species and/or how humans are affecting animal habitats and populations. Run time 02:37.
Population: State of the Earth
In 2006 the human population pushed past 6.5 billion. Every minute, 153 people are born, leading to possibly deadly consequences. This movie discuses the environmental impact the growing population has. Also, learn what we can do like cutting down on our carbon footprint, using bio gas, walking instead of driving, and consuming less. Run time 04:11.
Antarctica: A Challenging Work Day
For many scientists, having the opportunity to work in Antarctica is a dream come true. Its remoteness and extreme environment make it, arguably, the most untouched region on the planet. Today, more than 20 nations maintain research facilities there under a treaty that dedicates the entire continent to peaceful scientific investigation. In this video segment adapted from NOVA, see how the members of one research team cope with the inhospitable climate and other environmental hazards during their
Harry Potter's Invisibility Cloak - Real Science
A team led by scientists at Duke University's Pratt School of Engineering has demonstrated the first working "invisibility cloak." Harry Potter's invisibility cloak is on its way to becoming reality!

Exploring Wisconsin Our Home-Interacting With Our Environment
Interacting with Our Environment - The interaction between people and the environment is the focus of this program. It will show the fragility of both humans and the environment, how people use the environment to sustain life, and the mutually dependent relationship between people and the land. Over time, the Wisconsin environment has undergone many changes. Once, most environmental changes were caused by natural phenomena. Today, most are caused by people. This program will help students
Civilian Conservation Corp
The CCC was President Roosevelt's answer to the environmental and economic challenges facing the country. Enlisting 250,000 workers in just two months, the CCC was an ambitious undertaking that brought several government agencies together in the effort. Comparison from today to economic climate in the 1930"s. (59:00)
Protecting a Pig From Summer Heat
Pigs that are cared for are protected from sunburn and summer heat with baths, mud, and shade. You can raise healthy pigs with these tips for keeping off the summer heat. Tips from a pig sanctuary Ironwood Pig Sanctuary, Arizona (where it gets very hot). The expert is Mary Schanz, who became very involved in environmental and animal rights issues more than 15 years ago. Filmmaker: Sarah Sher.
While the American system of politics has generally been defined as a two-party system, occasionally a third party emerges, influencing elections and siphoning important votes from the major parties. Third parties often begin as single-issue parties that oppose or promote a certain social, economic, or political topic. For example, the Republican Party formed in the 1850’s as a third party in opposition to slavery. Similarly, in 2000, Ralph Nader formed the Green Party that focused on environm
This interactive activity adapted from Indiana University features time-lapse videos that reveal the movement and growth of plants in their pursuit of light. Although plants have no choice about where they are rooted, they do respond to environmental cues in ways that enable them to survive. This interactive site includes five videos using time lapsed photography (no audio) with written explanations. The videos include: seed germination and gravity, light and dark responses, twining vines, pl
Agent Based Modeling of Complex Adaptive Systems (basics)
Our human society consists of many intertwined Large Scale Socio-Technical Systems (LSSTS), such as infrastructures, industrial networks, the financial systems etc. Environmental pressures created by these systems on Earth’s carrying capacity are leading to exhaustion of natural resources, loss of habitats and biodiversity, and are causing a resource and climate crisis. To avoid this sustainability crisis, we urgently need to transform our production and consumption patterns. Given that we, as
