Galileo: Discovering Jupiter's Moons
The telescope forever changed astronomy by providing more detailed views of distant objects than was previously possible. Galileo pioneered astronomy as the first person to study the celestial objects through a telescope. His observations, including the discovery of moons around Jupiter, helped revolutionize the way people thought about the universe. This video segment adapted from NOVA describes some of Galileo's first discoveries with the telescope. Closed captioning included. Run time 03:04.
Galileo on the Moon
Galileo used thought experiments to test many assumptions, including the notion that heavy objects fall more quickly than lighter objects when they are dropped. Lacking access to either a vacuum chamber or a planetary body that has no atmosphere, he nevertheless correctly predicted that all falling objects would accelerate at the same rate in the absence of air resistance. In this video segment from NASA, astronaut David Scott demonstrates the correctness of Galileo's prediction. Run time 0:47.
Galileo: Sun-Centered System
Before the 17th century, people generally believed that Earth was at the center of the universe. Galileo, however, was not afraid to challenge existing beliefs when he published his work in support of the Sun-centered, or heliocentric, Copernican theory. In this video segment adapted from NOVA, learn about the two opposing worldviews and the strong piece of evidence Galileo offered to support the heliocentric theory. Closed captioning included. Run time 05:06.
Galileo used his telescope to gather data about the heavens, and his observations and theories sparked much controversy. Contrary to the popular belief of the time, Galileo suggested that Earth was not the center of the universe. In this video segment adapted from NOVA, the importance of unbiased scientific inquiry is demonstrated by Galileo's observations of sunspots. Closed captioning included. Run time 03:42.
Leonardo Da Vinci -The Man Who Knew Everything

This one minute biography touches on the most important works of DaVinci including his art and inventions.
Siegfried Woldhek shows how he found the true face of Leonardo
This 4:21 video lecture is about the narrator's search for an image of Leonardo and the problem solving approach that he used. This is a wonderful video that shows students how they can use their powers of observation and deduction to reach conclusions.
Clouds and Precipitation by StudyJams
Clouds are made of water vapor and dust. When the water gets too heavy, it falls back to the Earth. Clouds are named according to their shape, such as cumulous, or puffy, stratus, or blanketed, and cirrus, or high and cold. Learn more about the types of clouds with this slide show from StudyJams. Vibrant images are set to music with information written under each photo. A short, self-checking quiz is also included with this link.

How Hurricanes are born from NASA
A downloadable video that shows how hurricanes are born by following the birth of Isabel from Africa to the United States. Needs some vocabulary to be fully understood. Also needs a large class map to help follow the video. Good explanation of how warm and cold ocean waters impact hurricanes. Effective video best downloaded.
Hurricane Katrina: Extreme Video
Storm Chaser Mike Theiss and Jim Reed takes you up close and personal with Hurricane Katrina. Note the sound and the alarms going off. Shows both inside and outside.

Slideshow About Katrina Damage on the Mississippi Gulf Coast
These before and after photos are breathtaking in their views of what a hurricane can do to even the most stout structures. There is also a slide that shows the force of the wind as it moved through the area. These could be used in conjunction with a Google Earth photo showing the area's landforms. Students can use these to gain an understanding of elevation as well as a lesson on hurricanes and hurricane preparation.
Hurricanes: New Tools for Predicting
Hurricane Katrina, which struck New Orleans and other Gulf Coast communities on August 29, 2005, provided the worst kind of reminder of the importance of accurate hurricane prediction — and of heeding those predictions. This video segment adapted from NOVA scienceNOW a year before Katrina struck, describes the current state of research into what causes hurricanes and how scientists are now able to "see" inside the storms in their ongoing efforts to more accurately predict both the path and int
