Jonathan Berger on the Social Ethics of Music
Stanford University professor, Jonathan Berger, presents a range of compositions, including his piece called Jiyeh, written in response to an ecological disaster arising from an act of war, in this profoundly moving lecture (and accompanying auditory soundscape) reflecting on the idea of socially responsible music.

Soil Fertility Protocol
The purpose of this resource is to measure the amounts of nitrogen, phosphorous and potassium in each horizon in a soil profile. Using a NPK test kit, students mix a dry, sieved soil sample into a solution and chemically extract the N, P, and K as nitrate, phosphate, and potassium. The N, P, and K amounts in the sample are determined by comparing the solution to a color chart. Students describe the N, P, K amounts as high, medium, low, or none. These measurements are conducted three times for ea
Building a Thermometer
The purpose of this activity is to build an instrument that can be used to measure water temperature. Students construct a soda-bottle thermometer, which is similar to the thermometer used by GLOBE schools. Both are based on the principle that most substances expand and contract as their temperature changes. This experiment also demonstrates the principle of heat transfer. The intended outcome is that students will understand why and how a standard thermometer works.
How the Body Responds to Excercise
This video segment adapted from NOVA describes the effect of exercise on the body and defines one measure used to gauge aerobic fitness. VO2 max (maximal volume of oxygen uptake) is a measurement of how well the body gets and consumes the oxygen that muscles need in order to sustain activity. Learn how the entire cardiovascular system benefits from exercise and how the body's response to the demands of physical activity is a survival mechanism. Nice illustration of how the respiratory,circulator
Computer Basics : What Is a Laser Mouse?
A laser mouse uses a laser light, as opposed to an LED or infrared light, to measure the movement of the computer mouse and transmit the data to the cursor on the screen. Learn about the difference between a laser mouse and an LED mouse, including information on precision, with tips from a certified computer technician in this video on computers. (1:56)
Dog Whisperer: A Lesson in Aggression
Cesar takes an aggressive German Sheppard named Troy to his long time colleague to measure his "level of aggression". This video is part of a series run by National Geographic on dog behaviors. Run time 04:15.
How Does Broadcast Radio Work?
Broadcast radio jobs can require attending broadcasting
school, but are much easier to attain today due to the low competition
levels in radio news. Learn about how to become a broadcast radio disc jockey from an award-winning journalist in this video. Run time 2:52
This video shows an animal model (rabbit I think) of a lung ventilated at different levels of PEEP (0 cmH2O - 15 cmH2O) and the recruitment and derecuitment that occurs. THe video appears to be shot in a classroom or lab with the profesor briefly explaining what is seen on the screen. Younger students will not understand the PEEP levels, but may certainly enjoy seeing the lungs expand and contract. Run time 01:01.

Estimate and Measure Temperature
Learn to estimate and measure temperature in Fahrenheit and Celsius in this white board presentation. The off-screen teacher/narrator uses models of two thermometers to solve a word problems. Next, the teacher uses conversion formulas. The teacher suggests that benchmark comparisons can help students. For example, water freezes at 32 degrees F and at 0 degrees C. The sound is slightly scratchy.
Measuring Your Body with Curious George
The children trace their bodies onto large pieces of paper and then use cubes to count and measure how tall they are. One child uses popsicle sticks because they ran out of cubes. The teacher addresses how they should have all used the same standard in measurement. This video could also be used with older students in science for an example of controls and variables in an experiment.
Great Circle – A Virtual Manipulative
Use a 3D globe to visualize and measure the shortest path between cities. This manipulative shows the great circle route and the great circle distance between a number of cities around the globe. Click and drag to rotate the globe.
To see the route and distance between any two cities on the map, simply click on the red dots representing the two cities. Two routes are shown. The green route is the smaller arc of the great circle containing your two cities. The approximate great circ
PLATO - Online Education & Courseware
On June 3, 2010, the Computer History Museum hosted a 6-session conference on the PLATO learning system. Session 4 was entitled "Online Education & Courseware: Lessons Learned, Insights Gleaned." Session 4 Description: Thousands of hours of courseware in dozens of academic disciplines were developed on the PLATO system, and deployed to thousands of students at levels from K-20. The open environment and sophisticated authoring tools enabled any interested and creative instructor to develop cours
Beowulf in Old English (Prologue)
The first verses of Beowulf recited in Old English (Anglo-Saxon) combined with scenes from the 2006 Motion Picture "Beowulf and Grendel" and the Braveheart soundtrack. This is a very interesting video that can show students just how much the English language has changed since when Beowulf was written. Subtitles are included so students can have fun trying to see if they can recognize words.
How to Add Mixed Numbers
This is a slideshow presentation about adding mixed numbers. It is a presentation of how a 5th grade class and their examples of adding mixed numbers. It is set to peaceful music, and provides facts to remember when adding mixed numbers.
Climate Change: Taking the temperature 50 years down the road
Even though the issue of climate change has been known for about decades, it has only been in the past five years or so that the topic has been seriously addressed. Governments and businesses have started to adapt their policies and practices, mostly due to pressure from the public.
On the loss of legitimacy and contagion of scandals
How do consumers react when the ‘bad apple’ is a scandal-ridden financial company? How much do sales suffer as a result of its wrongdoing? What are the effects on sales of other similar companies such as pension providers, fund managers, and insurers?
The Effects of Green House Gases
Methane, water vapour, nitrous oxide and ozone are the green houses
gases, which exist in the earth’s atmosphere. They absorb thermal
radiations that are breathed out by the earth’s surface and reflect it
back to the earth, thereby serving as a blanket preventing the earth
from heat loss and keeping temperatures constant and perfect for animals
to live, and plants to grow.
For years now, rising temperatures have been a particularly hot topic
"Environmental Degradation and Deforestation in Thailand and Cambodia"
Alan Kolata is Neukom Family Distinguished Service Professor of Anthropology, The University of Chicago. There is little doubt that climate change, deforestation, erosion, and the unequal distribution of natural resources around the globe are of pressing importance everywhere, but these problems are perhaps most acute in Asia, home to 64 percent of the world’s population. Much of this population (1 and 1.3 billion, respectively) is concentrated in India and China, two countries with rapidly g
