Note from the author:
To finish this assignment, you should pick up the IMF graphic organizer in class and fill it out to create focused notes for the week. Some notes are added below to help you understand how to fill out the organizer.
Make sure you have an explanation or a diagram that explains why oil has good adhesion (sticks to itself) or geckos can stick to ceilings. Remember dispersion forces are tiny, but alot of dispersion forces can really add up.
