Ecology: Material Cycle
Discusses the continuous natural cyce of raw materials, such as, water, oxygen, carbon dioxide, and nitrogen. The video briefly reviews the water cycle, oxygen/carbon cycle, photosynthesis, food chains, and the nitrogen cycle. Run time 02:52.
Cuba: The Accidental Eden
While the tourist industry has hurt biodiversity in much of the Caribbean, Cuba's relative isolation has left its wildlife untouched. Now, Cuba is a safe haven for rare and intriguing indigenous animals, migrating birds and marine creatures. But as the prospect of the US trade embargo being lifted looms, a surge in tourism is predicted. What will happen to Cuba's ecological riches in the process? (49:54)
Ecology is the study of the interactions between organisms and the environment. There are various scales of study in ecology, the largest being at the level of the ecosystem, the next being at the level of the community and the smallest is at the population level. (02:02)
Overview of Biosphere
The biosphere is the zone of air, land and water where organisms exist. It is commonly known as the global sum of all ecosystems and consists of several layers including the atmosphere, the lithosphere and the hydrosphere. (00:59)
Behavioral ecology is the study of ecological and evolutionary causes of behavior in organisms. Behavior is influenced by genetics and the environment and should increase the reproductive fitness of a species. Common behaviors studied including things like learning, communication, foraging, reproductive strategies and social behaviors. (04:38)
Population ecology is the study of populations and their interactions with the environment. A population is a group of individuals of a species in a particular area. Population ecology studies things like population growth, selection strategies, population distribution, demographics and how populations evolve and adapt. (02:26)
Statistics - Sampling Distribution
Using different equations we can find the "meanest of the mean" in our sampling distribution. (01:19) This brief video is a little dark, but the sound quality is good.
Statistics: Sample vs. Population Mean - Khan Academy
In this video, Mr. Khan, explains the difference between the mean of a sample and the mean of a population. (06:41) Mr. Khan uses computer software for demonstration.
Statistics: Variance of a Population - Khan Academy
Mr. Khan continues his discussion about statisitics. This is the video after Sample vs. Population Mean. In this video, he discusses the variance of a population. (12:22)
Feeding Time for the Raven
Ravens demonstrate several of the commonly accepted indicators of animal intelligence. Some of these indicators can best be observed when ravens are scavenging for food. In this video segment from Nature, ravens exhibit their bird brain power by counting and hiding their food. Nice illustration of a scavenger. Closed captioning included. Run time 04:00.

Geysers - Stream Team
From Dragonfly TV. Phoebe and Shannon love exploring Yellowstone National Park. There are so many cool things to see: the canyon, waterfalls, wildlife, lakes, hot springs, and geysers! The girls went to Canyon Visitor Center to learn more about these features-especially the thermal basins, places where there are lots of geysers or hot springs. The park sits on a really big hot spot, made up of magma that rises from deep in the earth. All this magma heats up the ground water in the area and cr
Animal Life Cycles
In this video, students will observe various photographs of animal life cycles and their life cycle stages. It includes the life cycles of a butterfly, chicken, frog and mosquito. Images set to music. This is a good companion teaching resource for a science lesson/unit. (3:26)
Geometry - Similar Triangles
In this lesson, students review the idea that the ratios of the lengths
of corresponding sides of similar figures are equal. Students then use
this idea to find missing segment lengths in similar figures.
What types of plastic debris is killing the albatross?
A Hawaiian student looks at the plastic items found in stomachs of albatrosses, ingested from the Pacific ocean.
This video by School House Rock tells about nouns using a song and matching animation. Using various scenarios, such a putting a dime in the record machine, the song highlights various nouns (dime, Chubby Checker, etc.). It repeats that a noun is a person, place, or thing. A noun is a special word that names a person, place, or thing.
This is a fun teaching resource to introduce and/or reinforce nouns in the classroom and/or at home. (3:00)
UBC Talk on Open Notebook Science and Libraries
I presented a talk about Open Notebook Science and the implications for the future of libraries for Heather Morrison's class at the School of Libraries at the University of British Columbia on April 2, 2008. We did this over Skype so the questions are not very clear in the audio.
Temple Crest Park - Tampa Florida Plastic Pollution
Video encouraging cooperation and collaboration in the efforts to clean up the plastic pollution at a park in Tampa, Florida. Videos that document before and after clean up efforts are a good way to mobilize communities and measure impact.
How to Recycle Glass
To recycle glass, only recycle the containers that have held food, as window pane, ceramics and light bulbs can contaminate a batch of recycled glass. Avoid throwing away glass food containers--recycle them! (01:40)
