  • Ryan this is an excellent resource! Is it alright to use in my classroom. The kids all have I-pads and I think they would truly enjoy this1

Transcript

  • 1. Ch. 3 Sec. 2 Properties of Magma
  • 2. element <ul><li>substance that cannot be broken down into other substances </li></ul><ul><li>ex: carbon, hydrogen </li></ul>
  • 3. compound <ul><li>substance made of 2 or more elements that have been chemically combined </li></ul><ul><li>ex: water, carbon dioxide </li></ul>
  • 4. physical property <ul><li>any characteristic of a substance that can be observed or measured w/out changing composition of substance </li></ul><ul><li>ex: freezing point </li></ul>
  • 5. chemical property <ul><li>property that produces change in composition of matter </li></ul><ul><li>ex: ability to burn </li></ul>
  • 6. viscosity <ul><li>physical property </li></ul><ul><li>resistance of liquid to flowing </li></ul><ul><li>greater viscosity-slower it flows </li></ul>
  • 7. Question: How Fast do Liquids Flow? <ul><li>Hypothesis: I predict that ____________ </li></ul><ul><li>Procedure: See page 87 </li></ul>fast-lower viscosity-low 53 sec Vegetable Oil Slow-greater viscosity-high 98 sec Honey Flowed-Fast or slow/ Viscosity Time Liquid
  • 8. low viscosity high viscosity
  • 9. low viscosity high viscosity
  • 10. low viscosity high viscosity
  • 11. viscosity of magma <ul><li>depends on silica content &amp; temp. </li></ul><ul><li>silica = oxygen + silicon </li></ul><ul><li>more silica  higher viscosity </li></ul>
  • 12. pahoehoe <ul><li>fast-moving, hot lava </li></ul><ul><li>low viscosity </li></ul><ul><li>looks like solid mass of wrinkles, billows &amp; ropelike coils </li></ul>http://www.youtube.com/watch?v=0jry-iMXjik
  • 13. aa aa surge <ul><li>cooler &amp; slower than pahoehoe </li></ul><ul><li>hardens into rough chunks </li></ul>http://www.youtube.com/watch?v=iyIV5fd1Aww
  • 14. &nbsp;
  • 15. How are pahoehoe and aa different?
  • 16. The viscosity of magma depends on what two factors? <ul><li>silica content </li></ul><ul><li>temperature </li></ul>
  • 17. compound <ul><li>substance made of 2 or more elements that have been chemically combined </li></ul>
  • 18. element <ul><li>substance that cannot be broken down into other substances </li></ul>
  • 19. chemical property or physical property? <ul><li>ability to burn </li></ul>chemical property
  • 20. low viscosity high viscosity
  • 21. low viscosity high viscosity
  • 22. low viscosity high viscosity
