Capillary Action
• Capillary Action is the ability of a liquid to flow against gravity.
• Make a hypothesis about what you think will happen.
• Video: The Tissue Bridge
Where is each occurring in the demo?• Adhesion?• Cohesion?

How Water Works
• Answer the viewing questions on the Properties of Water worksheet as you watch
• Video: How Stuff Works – Water• ~35 min long
• More difficult alternate: Look up the answers online

Heat Capacity
• Heat capacity is how much heat is needed to raise the temperature of a substance by 1˚ C
• For example:

Heat Capacity
• Honolulu, Hawaii – High (Feb 5, 2014): 78 F (12:53 PM)– Low (Feb 5, 2014): 68 F (12:53 AM)– Past 10 days: ~10 degree difference
• Yuma, AZ– High (Feb 5, 2014): 70 F (1:57 PM)– Low (Feb 5, 2014): 53 F (11:57 PM)– Past 10 days: ~20-30 degree difference

Heat Capacity
• Video: Balloons on Fire
• Which has a greater heat capacity: – Air or water?
• Why?• What evidence is there to back up your
conclusion?

Surface Tension
• How many drops can you fit on a penny?• Video: Penny • What shape does the water make?
• Try a penny smeared with dish soap• Video: Penny with Soap

Surface Tension
• Water Strider• (Yes, it’s that guy from Top Gear.)
• In Spaaaaaaace– Where do you see adhesion?– Where do you see cohesion?

Polarity
• Water Bending
• Rub a balloon on the cloth. Hold the balloon to a trickle of water. What happens?
• Why does the water move towards the balloon (or PCV pipe)?
