  1. WelcometoExplore! Ice WorldsSharing The International Polar Year Through Library and After-School Program Networks

  2. Why Are We Here Today? • To explore activities and resources to bring the International Polar Year into children’s programs

  3. Explore! Ice Worlds • On line - http://www.lpi.usra.edu/education/explore/ice/activities/ • 3 modules of multiple activities • stand alone or together – use as you see fit! • Materials list, Book and Web Resources • Background Information and scientist’s talks • Tied to National Science Education Standards • Tested in library and after-school programs

  4. Today • Properties of Ice • Different Ices in the Solar System • Some Unexpected Places Ice May Exist Next Time • How and where and why we look for ice in the solar system • Ice on Earth

  5. Let’s Get Started! • Lots to Cover • Fast pace • Join us! • Interactive!!!!

  6. Module 1: All About Ice • The Melting Point • Amazing Expanding Ice • Tip of the Iceberg • Flubber Flows • Ice Bingo: An Ice Breaker Activity • An Ice Magic Show • Around the Block: An Ice Tour • That’s a N(ice) Temperature

  7. Have you ever … • Made a snowperson? • Thrown a snowball? • Gone ice fishing? • Gotten your tongue stuck on ice? • Had an ice cube tray “overflow?” • Slipped on ice?

  8. One way to get children started… what are their experiences with ice?

  9. States of Water: A Snow Mobile Connecting the Content Across the Activities What do you know about water and how it behaves?

  10. And Now, At no additional charge …An Ice Magic Show!

  11. An Ice Magic Show • Water exists in different states: • Liquid – water • Solid – ice • Gas – steam • Heating and cooling cause it to change states

  12. Around the Block: An Ice Tour What do you observe about ice? Investigator Journal!

  13. The Melting Point What happens when you put salt on ice?

  14. The Melting Point Why? Salt causes the ice to melt faster. Salt (and other substances) lowers the freezing point of water -- the water has to be colder to freeze The ice melts at colder temperatures

  15. That’s a N(ice) Temperature • What is the melting temperature of ice? • What is the freezing temperature of water?

  16. Amazing Expanding Ice • What happens to water when you freeze it? • How does it change?

  17. Overnight Activity! As ice is less dense than water, what happens when it is placed in water?

  18. The Tip of the Iceberg • Which is less dense - water or ice? • What will happen when the ice from the last activity is placed in a bowl of water?

  19. Based on what you learned, draw the top or bottom of these icebergs!

  20. Flubber Flows • Ice is what state of water? • How does it behave? It floats …

  21. 1. Amundsen Scott South Pole Station sits on a giant sheet of ice that is over a mile and a half thick.

  22. 1996 1997 1998 4. Each pole marked by an arrow once stood over the geographic south pole. The geographic south pole is not moving … so why have the poles moved?

  23. 5. A valley glacier in Alaska. The dark stripes are bands of rock that mark where smaller glaciers have flowed into the larger glacier.

  24. Time to Check the Flubber …

  25. Qori Kallis Glacier in the Andes of Peru (1978 and 2002) How has it changed? Predictions for 2010?

  26. States of Water: A Snow Mobile Connecting the Content Across the Activities Finish the Mobile!

  27. Module 2: Ice in the Solar System • Ice and Seek: What is Ice? • Ice Zones: Where We Look for Ice • Reflections on Ice: How We Look for Ice • Ice Quest: Who is Looking for Ice • Why Ice? Why We Look for Ice

  28. Module 2: Ice in the Solar System • Ice and Seek: What is Ice? • Ice Zones: Where We Look for Ice • Reflections on Ice: How We Look for Ice • Ice Quest: Who is Looking for Ice • Why Ice? Why We Look for Ice

  29. Ice in the Solar SystemWhat is Ice? Ice and Seek! • What is ice? • Where does it occur in our Solar system? • Is the ice the same everywhere?

  30. Mars

  31. Europa

  32. Europa

  33. Europa

  34. Water ice Carbon Dioxide ice

  35. Water ice

  36. Ice Zones – Where We Look for Ice • What does water need in order to exist as ice? • Where in the Solar System might we find this?

  37. What does this picture show? • Which planets are cold enough to have water ice at their surfaces?

  38. Earth side facing the Sun should be really really really hot • Side facing away should be really really really cold • But they are not … why?

  39. What about Mercury? • Or the Moon? • Atmospheres? • Temperatures? • Places where temperatures stay hot or cold?

  40. Where is Earth warmest? • Coldest? • Why? • Same for other planets?

  41. Could a planet or moon close to the Sun (or even far away!) have places that never get energy from the Sun? • Where? How?
