Solar System Adventure Science Activity Writing a science fiction story is not only fun, but a great way to learn about science. For this activity, students learn about the solar system and our galaxy from World Wide Web sites and write a science fiction story based on what they discover. WHAT YOU NEED Time online for your students Paper and pencils A printout of the story starters WHAT TO DO Have your students learn about the Solar System by directing them to The Galaxy Page or the Inquirer's Guide To The Universe (see below). Encourage students to download and print helpful information. The Galaxy Page The Galaxy Page , maintained by the University of Arizona chapter of SEDS (Students for the Exploration and Development of Space), hosts a rich, well-organized collection of links to space-related sites. Resources include virtual tours, graphics, and information categorized under The Solar System, Astronomy, Aerospace, and Visions of the Future. Aspiring science fiction writers will find a treasure trove of ideas for future spaceship designs, orbital colonies, and more in the Visions of the Future section.

Inventing the Solar System Early Greek Scientists Struggle to Explain How the Heavens Move by Ellen N. Brundige Table of Contents Introduction Mythology Homer and Hesiod: Chariots of Fire in the Vault of Heaven Other mythological schemes of the heaven ... Related Web Sites Introduction Since the first Egyptian farmers discovered the annual reappearence of Sirius just before dawn a few days before the yearly rising of the Nile, ancient civilizations around the Mediterranean have sought to explain the movements of the heavens as a sort of calendar to help guide them conduct earthly activities. Counting phases of the moon or observing the annual variations of daylength could, after many years' collection of observations, serve as vital indicators for planting and harvesting times, safe or

The Sun A Chinese legend held that there were 10 suns. Over the course of history, the Sun has been deified by many cultures. Today, we know that the five-billion-year-old Sun is a ball of gas that produces titanic explosions and supports life on Earth. More on the Sun Mercury Named for the winged messenger of Roman mythology, Mercury is the planet closest to the Sun. Its surface alternately bakes and freezes, due to its slow rotation. More on Mercury Venus Shrouded by insulating clouds, Venus has high temperatures at its surface. It was the first planet to be explored by visitor from Earth, the unmanned Mariner 2 in 1962. Due to its similar size and mass, it has been thought of as Earth's sister planet. More on Venus Earth Home to an astonishing variety of life, Earth is a complex array of interdependent ecosystems. As humanity continues to expand, the planet experiences more environmental pressure. Today, Earth is being studied from space at an unprecedented rate. More on Earth The Moon As Earth's nearest companion in the solar system, the Moon is thought to have been born from a cosmic impact about 4.5 billion years ago. The Moon was last visited by astronauts in 1972, and more recently has been studied by unmanned missions. More on the Moon Mars Named by the Romans after their god of war, Mars is the outermost of the four terrestrial planets. Its distinctive red color comes from iron oxide contained in the Martian soil. Two recent missions to the planet have failed, suspending future U.S. missions to Mars and prompting NASA to re-examine its guidelines.

These planets, together with the Sun, form the solar system Click on a planet below to view its specifications. The Planets are in Motion The planets move around the Sun along oval-shaped paths called orbits . One complete path around the Sun is called a revolution . Earth takes one year, or 3651/4 days, to make one revolution around the Sun. Planets that are farther away from the Sun take longer. Some planets have one or more moons . A moon orbits a planet in much the same way that the planets orbit the Sun. Each planet also spins (or rotates) on its axis. An axis is an imaginary line running through the center of a planet. The time it takes Earth to rotate on its axis equals one day. Facts About the Planets Unmanned Space Missions Big Questions Astronauts in Outer Space ... Did you know about Space?

Solar System T r u e T o S c a l e Why is this something special? Musik aus Musik ein Well, you can draw the spaces between the tracks of the planets true to scale and you can draw the sizes of the planets relative to the sun true to scale - but just try both on one sheet of paper! If you would use a normal sheet of paper and draw at one side the sun and at the other side the most outward planet Pluto true to scale in size and distance the planet would have a diameter of 0.1 thousandth of a millimeter. The earth wouldn't be much bigger, about 0.6 thousandth of a millimeter. You would see it only with a microscope but you couldn't find it on the paper. If you reversed would draw the earth 1 millimeter in diameter you would need for the whole solar system a sheet of paper of 500 meters length! Maybe somebody could check this? At a walk through a "way of planets" where the dimensions were explained I got the idea to show this in a web browser

These movies were calculated with Mathematica and compressed into zip files. After expanding by Zipit (for Mac) or Winzip (for Windows), you can see the movies with Movieplayer. These movies are periodic, so it is better to set the option of Movieplayer loop. Click the Figure. Simulations of Doppler effect You can get some QuickTime movies of Doppler effect here.
