Transcript of "8th Grade Ch. 2 Sec. 4 Using Space Science on earth"

  1. 1. Ch. 2 Sec. 4 Using Space Science on Earth
  2. 2. Space is nearly a vacuum. <ul><li>place that’s empty of all matter </li></ul><ul><li>(no solids, liquids, or gases) </li></ul><ul><li>NOTHING! </li></ul>
  3. 3. Extreme temps. in space <ul><li>Temperatures in space can range from the extremely cold, 100’s of degrees below freezing , to many hundreds of degrees above – especially if a spacecraft ventures close to the Sun. </li></ul>
  4. 4. microgravity <ul><li>feeling of weightlessness </li></ul><ul><li>falling thru. space w/ spacecraft </li></ul><ul><li>inertia keeps them moving forward </li></ul>
  5. 5. space spinoffs <ul><li>have uses on Earth </li></ul><ul><li>originally designed for use in space </li></ul>Space Shuttle spinoffs ESA Space Spinoffs Top 10 Space Spinoffs
  6. 6. stays over same place on Earth all the time
  7. 7. remote sensing <ul><li>collection of info w/o being in direct contact </li></ul><ul><li>Real World: NASA and a Dinosaur Named Dakota </li></ul>http://spaceplace.nasa.gov/en/educators/earth_from_space.pdf
  8. 8. Space spinoffs ear thermometer joystick invisible braces pacemaker battery satellite dish
  9. 9. TOP 10 NASA SPACE SPINOFFS
  10. 10. Time to review
  11. 11. Name 3 ways that conditions in space are different from conditions on Earth. <ul><li>3 ways that conditions in space are different from conditions on Earth are: </li></ul><ul><li>space is a near vacuum </li></ul><ul><li>major temperature extremes </li></ul><ul><li>microgravity </li></ul>
  12. 12. How have engineers designed spacecraft to operate in the special conditions of space? <ul><li>Engineers have designed spacecraft to be well insulated and airtight to operate in the special conditions of space. </li></ul>
  13. 13. What is a space spinoff? <ul><li>A space spinoff is an item that was originally designed for use in space but has uses on Earth . </li></ul>
  14. 14. How has medical science benefited from the space program? <ul><li>Medical science has benefited from the space program from the creation of medical spinoffs, such as lasers to clean clogged arteries, pacemakers that use longer lasting batteries, and computer-aided imaging techniques. </li></ul>
  15. 15. Name three uses of satellites that affect everyday life. <ul><li>3 uses of satellites that affect everyday life are: </li></ul><ul><li>transmitting television signals </li></ul><ul><li>gathering weather data </li></ul><ul><li>relaying computer data </li></ul>
  16. 16. What advantage would there be to placing a satellite in geostationary orbit? <ul><li>One advantage to placing a satellite in geostationary orbit would be because a geostationary satellite stays in the same place over Earth, signals to and from the satellite can always be directed to and from the same location in the sky. </li></ul>
  17. 17. How could a scientist use satellites to determine whether a rain forest was becoming smaller over time? <ul><li>A scientist could use satellites to determine whether a rain forest was becoming smaller over time by examining satellite images of an area taken over a period of years to find out whether the area covered by rain forest is changing. </li></ul>
  18. 18. Analyzing three decades of satellite imagery, researchers found that 19.8 million acres of Papua New Guinea’s tropical rain forest was lost between 1972 and 2002.
  19. 19. Make Keynote presentation about space spinoffs OR uses of satellites using clip art & Internet
