The Oil Spill's Unseen Culprits and Victims
The Gulf oil spill dwarfs comprehension, but we know this much: it's bad. Carl Safina scrapes out the facts in this blood-boiling cross-examination, arguing that the consequences will stretch far beyond the Gulf -- and many so-called solutions are making the situation worse. Carl Safina's writing explores the scientific, moral and social dimensions of our relationship with nature. This speech was given in June of 2010. Run time 19:56.
Inductive Patterns
In this video, Sal Khan uses toothpicks and houses to solve this logic problem. Mr. Khan uses the Paint Program (with different colors)Â to illustrate his points. The viewer may wish to open the video to 'full screen' as there is a lot of writing on a small black screen. Sal Khan was the recipient of the 2009Â Microsoft Tech Award in Education.
Statistics: Alternate Variance Formulas - Khan Academy
Using computer software for demonstrating, Mr. Khan, 'plays' (to use his word) with the formula for the variance of a population. (12:17) The screen gets a little 'busy'-- the viewer may want to open the screen to 'full view'
Columns: Experimenting with Paper Cups
Columns, vertical structural elements that are strong in compression, are good at propping things up. In this video segment adapted from ZOOM, the cast uses paper cups to illustrate what makes columns strong and why they sometimes collapse. By filling the cups with sand, they also show that even hollow columns of a weak material like paper can be made surprisingly strong. Closed captioning included. Run time 03:03.
An Aztec Sacrife

Ladybug Pajama Part
This video segment, adapted from QUEST, explains the unique behavior of a species of ladybug that spends most of its year feeding on the California coast but then migrates by the millions inland to spend the winter. Once they reach their destination, they huddle together to maintain temperature and moisture level in order to survive. Run time 02:46.
Little Brain, Big Journey
The Rufous hummingbird is a small wonder that, with respect to body size, migrates farther than any other creature on earth. The brightly colored, feisty bird breeds from southern Alaska to northern California and then spends the winter in Mexico. Though their brains are approximately the size of a grain of rice, Rufous hummingbirds have an excellent memory for locating flowers from year to year. In this video segment from Nature, learn about the little brain and big journey of the Rufous humm

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.
Calisphere Themed Collection - 1870-1900: Closing of the Frontier: Everyday Life and People
The images in this topic show how Californians in the late 19th century worked and played. Many of these photographs reflect the manual labor (mining, logging, agriculture) and services (like barber shops and grocery stores) that supported the rapid growth of cities and towns. As they do today, people spent their free time doing quiet activities like painting, enjoying themselves outdoors, riding bicycles and camping.
Calisphere Themed Collection - 1780-1880: California in Transition: Everyday Life, 1850s-1890s
The images in this topic depict everyday life in California during a time of explosive growth. Even as the state’s mix of cultures became more interconnected, they still managed to maintain and express their unique identities. People at work, at play, posing for formal portraits, and simply walking down the street are part of a diverse and vibrant population.
Calisphere Themed Collection - 1780-1880: California in Transition: Rich Resources
These images show the importance of both California's natural and human resource potential to the state’s development and subsequent wealth. Natural resources like water, lumber, and oil — along with human-driven resources like transportation, agriculture, and technology — have all contributed to California's growth. These natural resources drew many different ethnic groups to the state: human resources that would construct railways and aqueducts, plant crops and harvest them, strike it ri
