Swamps and Such - Natures Kidneys
This video series from WOSU Public Media uses the example of a wetland to explain the structure and functions of ecosystems and how ecosystems change over time. In these videos meet wetland scientist Dan Fink who hosts the program and examines the types of communities of plants, animals, birds and fish that abound in wetlands, the process of photosynthesis, and the complex relationship between water and productivity. Developed in collaboration with The Ohio State University Olentangy River Wetla
The Value of Wetlands
In this video segment adapted from Texas Parks and Wildlife Department, learn about the value of the wetlands ecosystems. Wetlands are essential habitats for plants and wildlife and a critical part of the water cycle. Yet they are under threat, largely due to the needs of a growing human population. The video suggests that humans must find a way to balance their needs while protecting and restoring wetlands. Closed captioning included. Run time 03:08.
The Busy Electron Oxidation and corrosion reactions are explained, and real world solutions to these problems are discussed. The principles of electrochemical cell design are explained through batteries, sensors, and a solar-powered car. New applications of lithium batteries are spurring medical and technological advances.

Beyond the Lava
Video takes place in the Kamchatka peninsula in Russia. There are more than 120 volcanoes in this area. Video photographer climbs down into the volcano to take photos. Video shows how he climbs down and the risks he takes to get the photos.
Solar Technology GE researcher Vlatko Vlatkovic discusses solar technology development at GE from the roof of GE's global research center in New York. It is a solar panel test set up. He shows a silicone solar cell and explains how the sun hits the cell and is converted to energy. He explains that the system is still very expensive and not very attractive and how they are trying to produce a more efficient, less expensive, and a better looking u

Coral Reef Ecosystem
This video shows a close up of a coral reef. Coral reefs are the most biologically diverse marine eco-systems on earth, rivaled only by the tropical rainforests on land. This video shows many different plants and animals close up. Run time 03:49.
This video segment adapted from FRONTLINE: "Heat" examines clean coal technology. It provides statistics for overall annual U.S. consumption as well as average household usage, and then explains the need for developing a cleaner way to convert coal into energy. Visit a Florida energy plant that turns solid coal into a clean-burning fuel gas (syngas), and learn about a new approach to capture and store carbon dioxide gas, a by-product of coal burning. Carbon dioxide is an important greenhouse gas
Dangers from Heat in the Karoo Biome
South Africa's Karoo desert gives a glimps into the damage hot , dry weather can bring. This desert is getting even hotter and drier than ever and the plant life is dying rapidly. Some of the plants are in grave danger of extinction. What is going on in this area could foreshadow what might happen everywhere. This video could also be used while discussing adaptations that plants have for hot, dry weather. Run time 03:16.
The Voltaic Pile
The Voltaic Pile may have been the first successful multi-cell battery. This video presents the history of this important device and explains how they are constructed. If you attempt to construct your own voltaic pile make sure you have adult supervision, someone with knowledge of electrical systems and safety procedures.
Dolly the cloned sheep
Dolly, an ewe, was the first successfully cloned mammal from an adult cell. Cloning efforts took place at the Roslin Institute in Midlothian, Scotland and was led by Ian Wilmut.This was a major scientific advancement. This two minute video is slow loading.
Energy Flow in the Coral Reef
In this video segment, adapted from NOVA, learn how energy from sunlight is transferred through the inhabitants of the reef ecosystem. Photosynthesizing plants and algae convert light energy into chemical energy, which then gets passed through the food web to plant eaters, flesh eaters, and ultimately to scavengers and decomposers. Closed captioning included. Run time 03:48.
Pearl and Hermes Population Assessments
This video segment adapted from the NOW-RAMP 2002 Expedition follows a team of U.S. Fish and Wildlife researchers as they visit the northwest tip of the Hawaiian Islands to document wildlife populations and help control invasive species. The Pearl and Hermes Atoll, one of the oldest landmasses in the Hawaiian Island chain, supports an impressive diversity of plants and animals but, like many islands, is vulnerable to invasive species. Closed captioning included. Run time 02:28.
DNA Replication Process
THe cell prepares for meosis just as it does for mitosis. Travel inside nucleus to see how the DNA replicates with this computer animated video clip. Run time 01:48.
How DNA Is Packaged and Copied In The Cell
Animation that shows how 6 ft of DNA is packaged into the tiny nucleus of the cell. The second half of the animation shows how replication occurs. Color animation. Run time 03:17.
Protein Assembly in a Cell
The video uses computer animation and narration to explain the process of protein synthesis. It shows the process within the context of the cell organelles with a narrative to explain each step. 3:02 min.
The Central Dogma- From DNA to Protein
3-D color animation that takes you into the cell and shows the detailed processes of transcription and translation. Has sound, but it is not needed, and is somewhat distracting. Subtitles are given to explain what is occurring in the animation. Would be useful as a review for students. 10:46 min.
Detailed view of the cell membrane and how it functions. 3-D color animation with narration. 1:23 min.
3-D color animation with narration which shows mitochondria producing ATP in a cell. 1:11 min.
HIV Replication and Life Cycle
HIV replication is a complex multi-staged process that includes crucial steps taking place on the exterior as well as the interior of the target host cell. The first three steps involved in cell entry are termed attachment, co-receptor binding and fusion. Each step is crucial to successful viral reproduction. Once HIV virus penetrates the cell, it releases its RNA into the cell. Run time 02:29.
Virus Lytic Cycle
The lytic is the viral reproductive cycle in which a virus takes over all metabolic activities of a cell; replicates many times and destroy its host cell. 3-D animation shows the steps of a lytic infection. Grades 5-12. 1:14 min.
