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.
The Discovery of Photosynthesis
This video segment from Interactive NOVA: "Earth" explores the history of plant biology. It takes the viewer from the earliest scientific hypotheses that plants ate dirt, to our present-day understanding of photosynthesis, the process by which plants use the sun's energy to convert carbon dioxide and water into carbohydrates, a storable form of chemical energy. Run time 02:33.
Photosynthesis: The Movie
This five minute animation about Photosynthesis in action must have a word list of hand out as it moves very rapidly and uses very difficult scientific words and principles. A few key vocabulary words include: ATP, ADP, Pi, electron transport train, hydrogen ions, water molecules, cytochrome b6f, ferredoxin NADP reductase, ATP synthase, and plastoquinone Qb. A text version of the narrative is also included on the website. (04:55)

plant and animal adaptations
This 2 1/2 minute slide show is set to music. Photos are large, clear and colorful with labels on each. Students must be able to read the brief labels to obtain the information. Several topics are covered, including examples of the parts of the plants we eat (roots, seeds, flowers, stems etc) plant dispersal (wind, water, burrs, animal waste etc) plant adaptations (broad leaves, needs, shallow roots, thorns, woody stems etc) and animal adaptations (camouflage, beak shapes, sharp teeth, cl
The evolution of plant life is the story of a journey from water to land. This professional video from Britannica explains various plant adaptations while showing close-up video footage. Run time 02:59.
Ecosystems and Material Cycles: Water, Carbon, and Sulfur
Professor George Wolfe discusses ecosystems and material cycles in this video from Thinkwell's online Biology series. The video uses lecture format along with illustrations and notes on a whiteboard to aid in the instruction of the water cycle, carbon cycle, and sulfur cycle. Run time 11:33.
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

Informative video about the lives of wood duck hatchlings. Shows hatching of the wood duck and their 30 foot leap from the nest to the water on the next day. Run time 02:11
Great Blue Heron
A great informational video on the great blue heron. This movie discusses the habitat needs of this bird such as tall trees for nesting and shallow water for hunting. You can see first hand a blue heron attempting to catch a baby alligator as well as their elaborate mating courtship. Run time 02:05.
For centuries the Amazon has been home to the most ferocious fresh-water monsters known to man...piranhas. Now, these deadly creatures are appearing in US lakes and rivers.
