ISS Update - June 21, 2012
The International Space Station video update for June 21, 2012.
NASA - Aurorae from Space on Vimeo
Lately, the International Space Station has been flying through geomagnetic storms, giving astronauts an close-up view of the aurora borealis just outside their windows. These videos were taken by the crew of Expedition 30 on board the International Space Station. First, get an introduction into the beauty of aurorae.
The sequence of shots was taken March 3, 2012 from 17:59:48 to 18:16:25 GMT, on a pass from eastern Kenya, near the Indian Ocean, to the South Ind
Do You Have the Strength?
In this activity, students squeeze a tennis ball to demonstrate the strength of the human heart. Working in teams, they think of ways to keep the heart beating if the natural mechanism were to fail. The goal of this activity is to get students to understand the strength and resilience of the heart.
The Beat Goes On (Activity)
In this activity, students learn about their heart rate and different ways it can be measured. Students construct a simple measurement device using clay and a toothpick, and then use this device to measure their heart rate under different circumstances (i.e., sitting, standing and jumping). Students make predictions and record data on a worksheet.
Dr. Ivor van Heerden - The inside story from one Louisiana scientist
Dr. Ivor van Heerden presented "The inside story from one Louisiana scientist" at the 2012 Public Affairs Conference: Culture of Connectivity. As former deputy director of Louisiana State University's Hurricane Center, Dr. Ivor van Heerden was one of several experts to presciently predict the disastrous consequences — including catastrophic levee failure — upon South Louisiana. Author of the tell-all, "The Storm: What Went Wrong In Katrina and Why — The Inside Story From One Louisiana S
Science Bulletins: Releasing a River
The network of rivers in the Sacramento--San Joaquin River Delta has a long history of human modification to fulfill residential and agricultural water needs. The Cosumnes River, which flows into the delta, is relatively unimpeded save for earthen levees erected along its banks to prevent natural flooding events from ruining nearby agricultural fields. Scientists from University of California--Davis recently analyzed the sediment trail of a flood that broke a Cosumnes levee using airborne light
17.433 International Relations of East Asia (MIT)
The aim of this course is to introduce and analyze the international relations of East Asia. With four great powers, three nuclear weapons states, and two of the world's largest economies, East Asia is one of the most dynamic and consequential regions in world politics. This course will examine the sources of conflict and cooperation in both periods, assessing competing explanations for key events in East Asia's international relations. Readings will be drawn from international relations theory,
Sum of Eleven Solitaire
Here is a card game with variations that kids can play alone or with a partner. Students take out face cards and joker cards. A dealer lays out 9 cards and students begin to match sums of eleven with 2 cards. Students must say aloud the equation. This would be a great center game to reinforce mastery of this important skill. (3:32)
Charles Garnier, The Paris Opéra, 1860-75 - Smart History at Khan Academy
Charles Garnier, The Paris Opéra, 1860-75. The experts are Dr. Beth Harris and Dr. Steven Zucker. (04:49)
Amusement Park Physics: Interactive Game
This is a complex series of choice a student makes in design rides. The site provides feedback on the student's choice. It could be used as a group activity or individual, but the directions must be read first. Free registration may be required.
Science Bulletins: Beetle Outbreaks and Climate Change
Scientists in western Canada have long been tracking the extent of the mountain pine beetle. This native insect kills weak and old lodgepole pine trees, thus promoting healthy growth of young forests. In times of drought, beetle populations can spike, spreading to healthy pine trees. Historically, cold winters kept beetle populations under control. A new study published in the journal Nature highlights how climate change is promoting pine beetle outbreaks—and how the outbreaks are contributing
Striped Bass Decline Points to Pollution
The striped bass, which can grow upwards of 45 kilograms (100 pounds), is a prize catch for sport fishers in the San Francisco Bay area—especially in recent decades, when big ones have been harder to find. Yet something other than fishing is causing the striped bass populations in the Bay to tumble dramatically. Years of study is revealing that many factors are to blame. They include pumping bay water for agriculture, invasive aquatic organisms, and pollution run-off from homes, industry, and
Geograph reaches Three Million Pictures

Science Bulletins: Waiting for Water in Africa's Sahel
Africa's Sahel, which lies between the Sahara to the north and Africa's tropical rain forests to the south, is vulnerable to many ecological problems that exacerbate one another, including overpopulation, drought, desertification, soil erosion, deforestation, and poor irrigation. This Bio Bulletin highlights Mali's Lake Faguibine and the surrounding region. Once the breadbasket of the country, the lake region is now almost completely dry. The Mali government and international aid projects are st
Shadows: ( An Interactive Game)
In this game, students drag a cameraman's equipment to make the smallest shadows possible. ( This link is for an interactive game and may take a few minutes to load.)
Stack - A Dice Game of Luck and Math
Stack is a dice game that is fun to play in large groups. It works better if you have lots and lots of different colored dice. Kids enjoy it and can even play it quietly. Each player takes turns rolling dice. When a number is rolled is already on board, you begin to stack the dice until you get to four. The color on top tells you who gets the point. This is a great resource to reinforce addition and social skills in the classroom. (2:40)
Endangered Animals of the Americas
This brief slide show is offered with a lesson plan that is designed to help the students identify what endangered animals are and where they live. A good group activity.
The Constitution: That Delicate Balance
This video's ingredients really don't get to the point until the 1:30 mark. At that time the panelist provide various questions and answers to what the entire program is going to cover. The videos that are listed below this video provide students an excellent variety of debate topics and are well worth viewing once the students have mastered a basic understanding of the Constitution.

Science Bulletins: Bilingual Brain 'Switch' Found
A recent study led by University College London neuroscientist Cathy Price reveals how the human brain is uniquely adapted to manage multiple languages. Language is processed in various regions of the left cerebral hemisphere. Previous studies using functional magnetic resonance imaging (fMRI) data showed that bilingual people activate the same general brain areas no matter what language they use. But Price's new experimental method, which involved measuring brain activity after showing subject
