Daisyworld Interactive Activity
Students use a JAVA interface design to explore the Daisy World model. The model is intended to illustrate a mechanism by which biota might optimize their abiotic environment by means of negative feedback. The model does not attempt to describe all of the possible mechanisms and feedbacks which might influence the ways in which the plants and climate develop. Instead, it is an heuristic model, that seeks to describe the ways in which this mechanism might work. The original model was developed by
Daisy World Model
The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary

Anges Rebelles, Les
"In six minutes, a conjuring trick combining special effects and the magic of painting enables us to enter the world of Jacques Brissot. It is a visual poem that humorously recounts the building of a collage inspired from artist Peter Breugel's 'La Chute des Anges Rebelles.'" Artist Jacques Brissot is shown adding to and retouching a large-scale collage work, lending insight into his compositional choices and his techniques and methods. Music is by Michel Arich, with Barney Wilen playing saxopho
Ancient African Kingdoms
'Blast from the Past' with Jesse Jackson. Program focuses on the history of three of Africa's ancient kingdoms: Ghana, Mali, and Songhay. To accomplish this, Say Brother Producer Marita Rivero and her guest Musa Eubanks (of the Afro Audiovisual Company of Boston) discuss and then introduce a filmstrip created by the Afro Audiovisual Company in conjunction with the Unitarian Universalist Association. The program serves to illustrate that the liberation of African Americans from colonized thinking
African Americans in the military
Carmen Fields interviews Frank Hector (World War II veteran) and Ralph Cooper (Vietnam veteran) about their experiences in the military. Hector talks about the accomplishments of African American soldiers and war veterans. Hector says that the military is a good experience for young African Americans. Cooper talks about the disproportionate numbers of African American soldiers in the front lines and the lack of services for veterans of color. Hector and Cooper talk about their opinions of Colin

Marie Sklodowska Curie, physicist 1867 to 1934
This resource provides a brief biography of Marie Curie, born Maria Sklodowska on November 7, 1867 in Warsaw, Poland. She would become famous for her research into radioactivity, and was the first woman to win a Nobel prize. She was awarded the 1911 Nobel prize for chemistry, for isolating radium and studying its chemical properties. In 1914 she helped found the Radium Institute in Paris, and was the Institute's first director. When the first world war broke out, Madame Curie thought X-rays woul
