1. Edible Plate Tectonics each student should have 1 double-stuff Oreo cookie
Special thanks to Dr. Bob Lillie of the Department of Geosciences who normally does this presentation as a guest lecture.

2. TECTONICS: From the Greek “tecton”
builder
architect
The study of large features on Earth’s surface and the processes that formed them.

3. PLATE TECTONICS: Large features… and processes…
continents
ocean basins
mountain ranges
and processes…
earthquakes
volcanic eruptions
due to movement of plates of Earth’s outer shell.

14. Oreo Psycho-Personality Test
Manner in which people eat Oreo cookies provides great insight into their personalities.
1. The whole thing at once.
2. One bite at a time.
3. Slow and methodical nibbles examining the results of each bite afterwards.
4. In little feverous nibbles.
5. Dunked in some liquid (milk, coffee …..)
6. Twisted apart, the inside, then the cookie.
7. Twisted apart, the inside, and toss the cookie.
8. Just the cookie, not the inside.
9. I just like to lick them, not eat them.
10. I don’t have a favorite way because I don’t like Oreos.
Psychologists have discovered that the manner in which people eat Oreo cookies provides great insight into their personalities. Choose which method best describes your favorite method of eating Oreos:

15. 6. Twisted apart, the inside, then the cookie.
You have a highly curious nature.
You take pleasure in breaking things apart to find out how they work, though not always able to put them back together, so you destroy all the evidence of your activities.
You deny your involvement when things go wrong.
You are a compulsive liar and exhibit deviant, if not criminal, behavior.
