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
"This Bulb" Hollywood Stars come together to Discuss how Reverse Effects of Greenhouse Gas
Natalie Portman, Kyra Sedwick, and Chloe Sevigny explain how simply changing a light bulb can help reverse the effects of greenhouse gasses. The clip encourages the use and explains the benefits of fluorescent light bulbs. This video also has music by Aimee Mann. Run time 01:45.
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.
Virus Lysogenic Cycle
In a lysogenic cycle, viral nucleid acid becomes part of the host cell chromosome and it's replicated with it. Eventually the virus enters a lytic cycle and kills the host cell. 3-D animation takes you through the steps of the lysogenic cycle. Grades 7-12. 1:25 min.
Euglena Binary Fission
This is a few minutes of the late stages of euglena undergoing binary fission. Flagellate formed, but animals moved away before final separation occurred. Microscopic imaging set to music. Good color and focus. Grades 5-12. 3:12 min.
Busasaurus - Magic School Bus
Were dinosaurs the biggest, meanest animals that ever lived? To find out, the kids at Magic School Bus travel back to the Late Cretaceous Period - 67 million years ago. There, they see dinosaurs eat, hunt, rest, and fight. Some even take care of baby dinosaurs! The kids discover that not all dinosaurs were huge - some were as small as rabbits. And most dinosaurs weren't killers - they preferred plants to dino-burgers. But one meat eater - Tyrannosaurus rex - has a taste for a Magic School Bus sa
Magic School Bus Goes to Mussel Beach
Join Ms. Frizzle and the class as they travel to the beach and learn more about high tides and low tides. This Magic School Bus video will teach the following two concepts: (1) The intertidal zone is the ocean shore area between the high-tide and the low-tide lines. and (2) Plants and animals on a rocky shore choose homes high up, midway, or low down in the zone, based on how much battering by waves and drying out they can tolerate. Run time 22 minutes.
Photosynthesis, Part 1
This is a short slidecast of the process of photosynthesis that starts with a defintion. A quote from the video: "The primary function of photosynthesis is to produce organic compounds useful to the cell. This is accomplished by using light, carbon dioxide, and water. Overall, photosynthesis converts light energy from the Sun to chemical energy."
