  • 1. • What is so special about the water in this photograph? Copyright © 2010 Ryan P. Murphy
  • 2. • http://sciencepowerpoint.com/
  • 3. • RED SLIDE: These are notes that are very important and should be recorded in your science journal. Copyright © 2010 Ryan P. Murphy
  • 4. -Nice neat notes that are legible and use indentations when appropriate. -Example of indent. -Skip a line between topics -Don’t skip pages -Make visuals clear and well drawn.
  • 5. • RED SLIDE: These are notes that are very important and should be recorded in your science journal. • BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly. Copyright © 2010 Ryan P. Murphy
  • 6. • Available Sheet: Properties of Water. – Note: This will be due at the end of Part III. – Bring to class everyday.
  • 7. • Available Sheet: Properties of Water. – Note: This will be due at the end of Part III. – Bring to class everyday.
  • 8. • Activity or Demonstration. Surface Tension. – Caution! Pepper is dangerous, wear eye protection. – Sprinkle pepper into water. – Dab detergent on toothpick and touch.
  • 9. • Activity! • Try to float a paperclip on water. • Record your method? • How is this possible? • What will happen if you touch the surface with detergent? Copyright © 2010 Ryan P. Murphy
  • 10. Surface tension: Water molecules tend toSurface tension: Water molecules tend to stick to themselves instead of the air.stick to themselves instead of the air. This creates a small film over the water.This creates a small film over the water. Copyright © 2010 Ryan P. Murphy

  • 13. Water Molecules sticking to themselves because the are polar Water doesn’t cling to Oxygen and Nitrogen in Air
  • 14. • The Water strider takes advantage of surface tension. – It’s built to walk on water and feeds on insects that aren’t.
  • 15. • The Water strider takes advantage of surface tension. – It’s built to walk on water and feeds on insects that aren’t.
  • 16. • Video Link! The World of the Water Strider – http://www.youtube.com/watch?v=RphuMEUY3Og
  • 17. • The Jesus Lizard: (Basiliscus Plumifrons) – Has long toes and runs in a way that it can travel across the water to avoid predators. – Video! (Optional) – http://www.youtube.com/watch?v=M6ypoyZRTkg
  • 18. • Surface tension is what allows snowmobilers and dirt bikers to perform a stunt called skimming. – It’s illegal in many states and unsafe. Copyright © 2010 Ryan P. Murphy
  • 19. • Skimboarding is a perfectly safe and fun way to experience the thrills of surface tension. Copyright © 2010 Ryan P. Murphy
  • 20. • Water skiing is another example of riding along the surface tension.
  • 21. • Water skiing is another example of riding along the surface tension. – It uses many other forces and requires velocity from the boat.
  • 22. • Hydroplaning: The loss of contact between a tire and a deck surface when the tire planes or glides on a film of water. Copyright © 2010 Ryan P. Murphy
  • 23. • Video Link! Hydroplaning. – http://www.youtube.com/watch?v=TdwuftIUwYY Copyright © 2010 Ryan P. Murphy

  • 29. • Please describe the water temperature in early June in a lake.
  • 30. • Please describe the water temperature in early June in a lake. Chilly!
  • 31. • The lake is still cold in June because it takes a lot of energy to warm up a large body of water. Copyright © 2010 Ryan P. Murphy

  • 34. • Please describe the water temperature in September in the same lake. Copyright © 2010 Ryan P. Murphy
  • 35. • Please describe the water temperature in September in the same lake. Warmer! Copyright © 2010 Ryan P. Murphy
  • 36. • Please describe the water temperature in September in the same lake. Warmer! Copyright © 2010 Ryan P. Murphy
  • 37. • No, it takes a lot of energy to cool it down. Copyright © 2010 Ryan P. Murphy
  • 38. • No, it takes a lot of energy to cool it down. Copyright © 2010 Ryan P. Murphy
  • 39. • In late fall / early winter, the temperatures near the sea coast are usually higher because the oceans are still releasing stored energy from the summer.
  • 40. • In late fall / early winter, the temperatures near the sea coast are usually higher because the oceans are still releasing stored energy from the summer.
  • 41. • In late fall / early winter, the temperatures near the sea coast are usually higher because the oceans are still releasing stored energy from the summer.
  • 42. • The high specific heat of water means that a lake won’t freeze or heat up suddenly.
  • 43. • The high specific heat of water means that a lake won’t freeze or heat up suddenly. – This gives aquatic organisms a chance to adjust to temperature changes slowly.
  • 44. • How long before you can put your hand in this water once removed from the stove?
