5.2 ASSIGNMENT: Science Blog: Water (Due November 30)

ASSIGNMENT: Science Blog: Water (10 points)

This Week's Science Blog Topic: For this week's blog entry watch the video below and answer the questions that follow. 

• In our two-dimensional molecular picture of ice (at 2:30), how many hydrogen atoms surround every oxygen atom? How many oxygen atoms surround every hydrogen atom? But remember that real life is three-dimensional. Do some research and find the most common molecular structure of ice. Study it closely and figure out how many hydrogens surround each oxygen and how many oxygens surround each hydrogen. Is our 2D model a good approximation for the 3D reality? Why or why not?

• Besides sushi, lobster rolls, and James Cameron’s Oscar, what else would be different if ice didn’t float on water? Come up with as many examples as you can, and explain each one.

Blog Guidelines: 

• Each blog post should be at least one paragraph (3-5 sentences minimum).
