Resource	Grade Level	Media Type
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
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
Eclipse of the Century This video segment adapted from NOVA features spectacular footage from the 1991 solar eclipse that fortuitously occurred directly over several major astronomical observatories in Hawaiʻi.	3-12	QuickTime Video
The Elements: Forged in Stars The story of how elements from lithium to uranium are created by stars is illustrated through animation and a hands-on periodic table in this video segment adapted from NOVA.	6-12	QuickTime Video
Explore the Moon See what it is like to walk on the Moon by viewing this collection of QuickTime images from NOVA Online. Stunning 360-degree panoramas from each of the six successful Apollo Moon landings are featured.	3-12	QuickTime Interactive
Extreme Temperatures on the Moon In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.	3-12	QuickTime Video
Galileo: Discovering Jupiter's Moons This video segment adapted from NOVA shows how Galileo, using his newly developed refracting telescope, observed four of Jupiter's moons, the first astronomical bodies to be discovered since ancient times.	3-12	QuickTime Video
Galileo on the Moon Watch Apollo 15 astronaut David Scott perform Galileo's falling objects experiment on the Moon in this video segment from NASA.	3-12	QuickTime Video
Galileo: Sun-Centered System In the early 1600s, most people believed that the Sun revolved around a stationary Earth. This video segment adapted from NOVA tells how Galileo proved that the Sun, not Earth, is at the center of our universe.	3-12	QuickTime Video
Galileo: Sunspots This video segment adapted from NOVA shows how Galileo used his telescope to carefully observe and study sunspots.	3-12	QuickTime Video
Gallery of Auroras View this stunning collection of auroral displays from NOVA Online to find out why auroras appear in different colors and shapes and whether they occur on other planets.	3-12	Flash Interactive
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
Mars Dead or Alive: A Hostile Environment This NOVA video segment describes the challenges presented by the frozen desert environment of Mars to NASA engineers designing two robots that will journey millions of miles to the red planet.	6-12	QuickTime Video
Mars Dead or Alive: Mars Up Close NASA scientist Steve Squyres narrates this visual tour from NOVA Online of the most revealing discoveries made by the Spirit and Opportunity rovers on Mars.	6-12	Flash Interactive
Mars Dead or Alive: Welcome to Mars This video segment from NOVA features the dramatic landing of the Spirit and Opportunity rovers on Mars.	6-12	QuickTime Video
Mars Dead or Alive: Where to Land? In this video segment from NOVA, engineers and scientists designing the Spirit and Opportunity rovers struggle to choose landing spots both safe enough for landing and geologically promising.	6-12	QuickTime Video
The Origin of the Elements This video segment adapted from NOVA explains the origin of the elements and how scientists use unique element profiles to identify supernova types.	6-12	QuickTime Video
The Origin of the Moon This video segment adapted from NOVA follows the Apollo 15 astronauts as they collect samples of ancient rock from the Moon's crust, whose discovery helps lead to a radical new theory about the Moon's origin.	6-12	QuickTime Video
The Search for Another Earth This NASA video provides an overview of technology under development to explore the planets and stars outside our solar system. These will be the most sensitive instruments built to date.	3-12	Unknown
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
A Strange New Planet This video segment adapted from NOVA features the first planet to be discovered outside our solar system. Its surprisingly large size and short orbit sent scientists back to their data and led them to discover similar planets.	6-12	QuickTime Video
Theories This lesson will help the students understand that science theories change in the face of new evidence, but those changes can be slow in coming.	5-8	Lesson Plan
Total Solar Eclipse Animation This brief animation adapted from NOVA illustrates how total solar eclipses form and explains the stages from first contact to totality.	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
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
