All Planet Sizes This illustration from the Lunar and Planetary Laboratory shows the approximate sizes of the planets relative to each other. Note that the planets are not shown at appropriate distances from the Sun.	3-12	JPEG Image
Are We Alone? This video segment adapted from NOVA features a variety of scientific perspectives on the age old question, "Are we alone in the universe?" Animations make vivid the improbability that we could intercept a radio wave signaling extra terrestrial intelligence.	6-12	QuickTime Video
Characteristics of the Sun This video segment adapted from NASA describes the basic characteristics of our star, the Sun.	3-12	QuickTime Video
Development of a Habitable Planet Students investigate the origin of the elements, the process of planet formation, the evolution of life on Earth, and the conditions necessary for life as we know it.	6-12	Lesson Plan
Earth as a System This visualization adapted from NASA maps progressive global changes onto a rotating globe. Earth's atmosphere, hydrosphere, geosphere, and biosphere are shown to be dynamic and interconnected.	6-12	QuickTime Video
Expedition 8 Crew Talks to Students in Japan In this video segment adapted from NASA, students in Matsuyama City, Japan, interview Expedition 8 Commander and NASA Science Officer Mike Foale and Flight Engineer Alexander Kaleri about life and work aboard the International Space Station.	K-8	QuickTime Video
Jupiter: Earth's Shield Jupiter's immense gravity protects Earth from asteroids. In this video segment adapted from NOVA, scientists searching for signs of life in the universe identify solar systems with Jupiter-like planets that may be shielding smaller nearby Earth-like planets from comets and asteroids.	6-12	QuickTime Video
Meteor Showers This video segment adapted from NASA uses animation to illustrate the properties of meteor showers and comets. Included is are visualizations of a comet's tail and of Earth passing through a debris stream left behind by meteoroids.	3-8	Flash Interactive
A New Theory of Lightning In this video segment adapted from NOVA scienceNOW, follow scientists as they test a new theory suggesting that lightning here on Earth is triggered by cosmic rays from far-away dying stars.	6-12	QuickTime Video
Solar Eclipses What is a solar eclipse and why are they only visible in some parts of the world? In this video segment adapted from NASA, astronomer Susan Stolovy uses animations to provide an answer to these questions.	3-8	QuickTime Video
Solar Magnetism This video segment adapted from NOVA describes how the Sun's magnetism can have an effect here on Earth, from dramatic auroras to a mini-Ice Age in the 1600s.	6-12	QuickTime Video
Solar Wind's Effect on Earth This video segment adapted from NASA describes solar storms and their effects on Earth. Animations of coronal mass ejections and solar cycles help explain what we know, and what we can predict, about solar activity.	3-12	QuickTime Video
The Wall of Time This illustrated timeline from the Lunar and Planetary Institute provides a journey through four-and-a-half billion years of time from the birth of our solar system to its current existence today.	6-12	JPEG Image
Why Doesn't the Moon Fall Down? In this animated video segment adapted from NASA, astronomer Doris Daou explains how the forces of speed and gravity keep the Moon in a constant orbit around Earth.	3-8	QuickTime Video
Your Weight on Other Worlds This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.	6-12	HTML Interactive
