6. Water Characteristics Page 40

7. What is water? Frayer Polar Molecule NOT a Polar molecule These have regions with a slightly positive and slightly negative charge so they attract, like a magnet Molecule that shares the bonds more equally examples fats & oils. What is water? Hydrogen bond Looks like The attraction between slightly positive Hydrogen atom and a slightly negative atom. One hydrogen bond is weak , but many hydrogen bonds are strong

8. Hydrogen bonding Demonstration • How many drops of water do you think will fit on a penny before the water breaks? • Write it on the corner of your paper and lets see who’s closest. • http://www.youtube.com/watch?v=tv4Jrc06yLA&feature=related&safety_mode=true&persist_safety_mode=1&safe=active

9. Water Properties High Specific Heat Cohesion Water sticks to each other- this creates surface tension. Water resists temperature changes which helps regulate cell temperatures. Properties of water Adhesion Solvent Water is usually present in a greater amount and its polarity helps dissolve other substances. Water is attracted to other substances-creates capillary action Ex. transpiration-process when plants and trees remove water from the soil

10. Properties of water Return • High Specific Heat & Solvent http://www.youtube.com/watch?v=QH1yphfgfFI&safety_mode=true&persist_safety_mode=1&safe=active

11. Cohesion … Return Helps insects walk across water

12. Adhesion Causes Capillary Action Which gives water the ability to “climb” structures

13. Return Adhesion Also Causes Water to … Attach to a silken spider web Form spheres & hold onto plant leaves
