The Quiet People: A Memoir
Kelle Groom reads from a manuscript in progress, which is a memoir incorporating private and public history in a lyrically structured narrative that examines contemporary concerns through the lens of the author's Finnish, Irish, and Wampanoag ancestors in Massachusetts. The title references ancestors who left little written record, which challenges Groom to make their lives visible and discover how her life connects to their earlier struggles. Speaker Biography: Kelle Groom is a poet and author
Historical skills: Dating documents
This module explains the different dating conventions employed in historical documents. For example, the system of dating by reference to a religious feast day and the year of the reigning monarch has little in common with the modern calendar. Even where a recognizable date is provided, it may not be what it at first appears.... The resource includes a glossary, bibliography and translation of relevant Latin numbers/phrases. Illustrative images of items from our collections appear throughout.
Southern California, 20 Ma to Present
This animation depicts the following: a) the rotation of the western Transverse Ranges block, b) the evolution of the San Andreas fault system, and c) the capture of pieces of the Pacific plate by North America.
Students examine images of galaxies and learn to recognize the various shapes used in the Hubble classification system. They can follow the site independently, using a worksheet that prompts them to answer questions in the text, then take a java "quiz" that requires them to place various galaxies in their correct positions on the Hubble "tuning fork." There is some supplemental material about galaxies and Hubble's observations.
Mars and the Teachable Moment
This article is written by a planetary science teacher, many of whose teenaged students, like many young Americans, believe that aliens have visited the solar system and left monuments behind. She uses recent photos of the "face on Mars" to demonstrate to them how an "obvious" alien artifact looks much more ordinary in photos taken at different times of the Martian day. This demonstration engages the students' prior beliefs about the solar system, but encourages students to think critically abou
New Kent School and the George W. Watkins School: From Freedom of Choice to Integration
looks at the 1968 Supreme Court ruling that ended a decade of resistance to school desegregation in the South (1955-1964) and triggered massive integration of schools (1968-1973). The New Kent and George W. Watkins schools illustrated typical characteristics of a southern rural school system that achieved ...

Aristotle Part 1
A video about Aristotle. He is one of the most important founding figures in Western philosophy. He was the first to create a comprehensive system of Western philosophy, encompassing morality and aesthetics, logic and science, politics and metaphysics. Aristotle's views on the physical sciences profoundly shaped medieval scholarship, and their influence extended well into the Renaissance, although they were ultimately replaced by modern physics. In the biological sciences, some of his obse

A Cow's Digestion
Cows are ruminants, animals with a unique digestive system that allows them to live on otherwise unpalatable foods by repeatedly regurgitating and rechewing them as "cud." The cud is then swallowed again and further digested by specialized bacterial, protozoal and fungal microbes that live in the rumen, one of the four compartments of a cow's stomach. Learn more about a cow's digestive system in this video segment from Nature. Closed captioning included. Run time 01:35.
Stable Mineral Assemblages in Metamorphic Rocks
This 81-slide PowerPoint presentation reviews the phase rule in terms of metamorphic systems, using the brucite-periclase system as an example. Binary and ternary chemographic diagrams are used to explain compatibility in mineral assemblages. The presentation covers ternary diagrams for complicated systems, ACF and AKF diagrams, projections from apical phases, and J.B. Thompson's A(K)FM diagram is used as an alternative tool to apply to pelitic rocks. Lastly, a set of rules is laid out to help c
Year 2010. The need of mobility has grown to excess since the first years of the millennium. That's why Tuboflex inc., the world's leading Human Resources Services organisation, created a complex tube system that make it possible to dislocate employees in real time, depending on demand.
What is a Planet?
What is a planet? This question has been pondered by many since the early Greeks came up with the word "planetes." Since then the number of "planets" in our solar system has fluctuated, sometimes numbering as high as 15, before it was determined that some were actually asteroids. (07;06)

The Confessions of an Erstwhile Land Rights Advocate
Late in his term on the High Court, Justice McHugh, one of the majority in the Mabo decision and one of the dissentients in Wik, expressed criticism of the "costly and time-consuming" native title system. He thought it was unable to fairly evaluate the competing legal rights of landholders and native-title holders. In this lecture presented by the National Centre for Indigenous Studies and the Centre for International and Public Law, Father Frank Brennan argues that the issue now is not the legi
