Transcript

  • 1. Ch. 2 Sec. 4 Using Space Science on Earth
  • 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. 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. 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. 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. stays over same place on Earth all the time
  • 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. Space spinoffs ear thermometer joystick invisible braces pacemaker battery satellite dish
  • 9. TOP 10 NASA SPACE SPINOFFS
  • 10. Time to review
  • 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. 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. 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. 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. 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. 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. 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. 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. Make Keynote presentation about space spinoffs OR uses of satellites using clip art & Internet
  • 20. 4 slides SLIDE 1 - TITLE SLIDE SLIDES 2-4 6 pictures- 2 pics per slide 3 facts in sentence format- 1 FACT PER SLIDE
