The Protestant Reformation - Part 2
Video is a continuation of part 1, which discusses Martin Luther.
Time Differences in Different Time Zones
The instructor uses computer software to demonstrate how to determine elapsed times. This one is more complicated than 'Time Differences, Part 1', as Mr. Khan focuses on elpased time across different time zones. The sreen is dark; the viewer may wish to open the screen to ful screen to see clearly. (08:59)
Introduction to Fractions
This lesson is a brief overview of fractions. First, it tells that fractions can represent part of a whole or part of a set. The lesson is a PowerPoint presentation and provides different illustrations of various fractions.
Volcanoes from Around the World
This video shows photographs of volcanoes from around the world. It is set to music and each photo gives the location of the volcano. It shows both dormant and erupting volcanoes. Music may be a bit distracting to the viewer. (06:07)
Mount Tempura: Potential Volcanic Eruption Analysis
This three minute shows how scientist think that Mount Tempura will throw so much ash into the air when it erupted that it could change the earth's climate. Yellowstone National Park is a huge volcano that
explodes every 600,000 years. The last time it blew was 640,000 years ago. This is a good video to show students to show how volcanic eruptions impact the Earth.
The Ring of Fire, Part 1
The Pacific Ring of Fire (or sometimes just the Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. (10:34)
This very brief video shows footage of a volcanic eruption. The video does have narration. Suitable for elementary, middle school, and high school students.
Population growth is loosely defined as the change in the amount of individuals of a specials in an area over time. To find the growth rate of a population, we take the number of individuals moving into an area and subtract the number of individuals moving out of an area by taking the birth rate, adding the immigration rate and subtracting the death rate and emigration rate. Two types of population growth are exponential and logistic growth.
The Life and Works of T.S. Eliot
Eliot's life, influence, and poetry from the bold originality of "Prufrock" to the probing, meditative style of "Four Quartets" are explored with photos, archival footage, and discussion with friends, critics, and scholars. (57:10)
The Precious Envelope
Without the earth's atmosphere, life would not be possible. Many different gases make up the atmosphere in varying concentrations. Human actions are threatening the delicate balance of these gases. The earth's atmosphere is examined through theories of chemical evolution; ozone depletion and the greenhouse effect are explained.
Why Study the Magnetosphere at the Poles? - Continued
The discussion Why study the magnetosphere at the poles? is continued by Shin-ichiro Oyama – STEL, Nagoya who notes that there are more dramatic changes at the poles, e.g., the aurora. He is intrigued by the many things still to be explored and the beauty of the Northern climate. Run time 01:23.
Interactions between the Magnetosphere and Earth's Magentic Fields
Part 3 in the discussion on What are the interactions between the magnetosphere and Earth's magnetic fields? Gabby Provan – Leicester is specifically studying how this affects the aurora through observation and radar data. Run time 02:49.
All magnetic fields can be thought to be produced by electric currents. The relationship between a current and the magnetic field it produces is a little peculiar geometrically, and takes some getting used to. The law of Biot and Sarvart, the force between electric currents, and Ampere's law.
This is Part 2 of the proton through a magnetic field problem.
More on the forces exerted by 2 current carrying wires on each other. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 11:01.
Magnetism 9: Electric Motors
Using a magnetic field to exert torque on a rotating circuit. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 10:36.

This animated short clip shows how the heart works as a pump to deliver blood to all parts of the body. Animation shows the heart muscle and the cycle of blood through arteries and veins in various stages. (01:51)
Inner Rocky Planets - Part 2
This video focuses on the little jagged worlds (or Inner Rocky Planets) from their birth to this day, and their compositions, structures, and their differences. (05:18)
