Water polarity, Hydrophobicity

* Grapes in Soda Demo

* Supplemented by the Lava-Lamp effect.

* Notes: Water properties

* Post Test - Review

*Homework: Water, Membranes:

Source: Pages 40-42, 81-82

1) Explain the word “Polar”. What are two examples of polarity in the world?

2) Why are water molecules attracted to one another?

3) How do polar molecules differ from non-polar molecules? How does this affect their interaction with water?

4) What happens when two non-polar substance are mixed with water at the same location?

Due: Wednesday

Honors (or EC):

i) Go through materials and surfaces in your home, and figure out if they are made of polar or non-polar substances.

Explain in detail: How could you tell which is polar and which is non-polar?

ii) Science News Opportunity: Use of hydrophobicity in food industry, medicine, cleaning supplies. More…
