Today I learned that minerals are classified by nine principals:
1) Shape (a 12 sided piece of pyrite is called a pyritohedron)
2) Cleavage (minerals that break into flat pieces/sides)
3) Fracture (opposite of cleavage)
4) Luster (metallic and nonmetallic)
5) Color (sometimes misleading)6) Streak (take a tile then scrape the mineral against it to determine its "true color")
7) Specific Gravity (weight)
8) Hardness
9) Other (magnetism, taste, etc.)
Classifications for Rocks:
1) Igneous (rocks formed by cool magma)
2) Sedimentary
3) Metamorphic

The picture is great! It is cool to see photos to accompany your text. Does that mean you are on a new computer?
I am really intrigued by the situation of hosting Indianola kids, and being your being able to remember when you were a student in that same trip! How cool. I am sure you can imagine what the kids thought when they were there. Does it seem like a long time ago since you were an elementary school student? Interesting.
Hey, those notes on Antartica are super interesting. I didn't know the highest, driest, coldest facts, nor most of the other facts you wrote. Though they are talking about climate change affecting Antartica, isn't it affecting the arctic more?
keep up the great journals, this is fascinating work, Laine!
It was definitely déjà vu to see those kids. Unfortunately, no. The computer situation is worsening because of connecting cables from my computer to our main modem. I am consulting Time Warner, my dad, Vince, my moms boyfriend and Vonage as we speak. I will be able to determine the near-final situation tomorrow.
My brain was scorched by science terms today! I was bombarded with a (nice) lecture from a quirky geophysicist by the name of Harun. Even though my brain is fizzled atm I am completely enjoying my work and mentors. I have about 5 new submentors.
It is hard to determine what is being affected more because of different variables (mass, deterioration rate, etc). To further delve into that question I will put it to Dr.Landis.
Guess what?! I am starting to learn Cyrillic! : )
