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)
Empty bottles. Full life.
Come on a tour of Tito Ingenieri's house in Quilmes, Argentina made from over six million empty glass bottles. Mr. Ingenieri has been building for 19 years and he still is adding more glass bottles to his home. (02:40)
Prince Edward Island Glass Bottle Buildings (3 of 3)
This bottle house on Prince Edward Island was made with 12,000 bottles.
North Korea's Crystal Meth Export 1
Pulitzer Center's grantee Isaac Stone Fish explains why crystal meth smuggling between North Korea and China is becoming far too critical. Fish visited Yanji, a city in the Korean Autonomous Province in northeastern China, where he investigated the extent of this widespread drug trade. Learn more about Isaac Stone Fish and his reports at Pulitzer Center's Meet the Journalists http://bit.ly/qDwIyT Read the full stories on North Korea's most addicting export and view photographs taken by Sean G
Calisphere Themed Collection - 1900-1940s: Emerging Industrial Order: Everyday Life and People
The images in this topic offer a glimpse of the ways people in cities and towns across California relaxed and entertained themselves during the first half of the 20th century. As new technologies and improved communications brought changes to the work week, people had more free time and new choices about how to spend it.
