Swinging Pendulum (for High School)
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.
Lesson plan with word search activity which aims to teach children about the metamorphosis and development of an amphibian from tadpole to frog.
"Human Rights are Women's Rights and Workers' Rights are Women's Rights:" May Chen on the United Nat

Earth Rotation from Galileo Imagery: 3600 x Real-Time
This animation is one in a series created to show an accurate representation of the Earths rotation at different temporal resolutions. The animation is created from images taken by the Galileo spacecraft during a close pass of the Earth on December 11-12, 1990. The animations range from real-time, in which no rotation can be perceived, to 3600 times real-time, in which both the Earths rotation and cloud motion can bee seen. The series also includes an animation in which the Earths rotation has b
"I Never Met a Black Person Who Was in the Communist Party Because of the Soviet Union:" Jack O'Dell
Jack O'Dell was a union organizer, a civil rights leader, and a member of the Communist Party. His political consciousness formed in the 1940's, when the African-American community became more assertive in their efforts to improve conditions and expand civil rights. Like many blacks, including one of his role models, Paul Robeson, O'Dell was drawn to the Communist Party because of their staunch stand against racism and segregation. During the 1940's, O'Dell found a welcoming environment in the N
The Free Speech Movement
The Free Speech Movement (FSM) was a college campus phenomenon inspired first by the struggle for civil rights and later fueled by opposition to the Vietnam War. The Free Speech Movement began in 1964, when students at the University of California, Berkeley protested a ban on on-campus political activities. The protest was led by several students, who also demanded their right to free speech and academic freedom. The FSM sparked an unprecedented wave of student activism and involvement. Many ima

"Quasi-Balanced Circulations in Oceans and Atmospheres, Fall 2009"
" This course introduces the students to dynamics of large-scale circulations in oceans and atmospheres. Basic concepts include mass and momentum conservation, hydrostatic and geostrophic balance, and pressure and other vertical coordinates. It covers the topics of fundamental conservation and balance principles for large-scale flow, generation and dissipation of quasi-balanced eddies, as well as equilibrated quasi-balanced systems. Examples of oceanic and atmospheric quasi-balanced flows, compu
This hands-on OLogy experiment uses Jell-O, fruit, nuts, and candy to demonstrate how space bends around anything that has mass. The activity begins with kid-friendly introductions to the concept of mass and Einstein's theory of bending space. The illustrated, step-by-step directions include notes about how the fruit, nuts, and candy represent stars, planets, and other objects in space. At the end, kids are encouraged to celebrate their newfound knowledge by digging into their edible space.
