Egg donation is not a trivial procedure and carries some risk. She would have to take a battery of injected fertility drugs and undergo a minor surgical procedure to retrieve the eggs. There is a small chance that she could lose her ovaries or even her life (search for ovary hyperstimulation syndrome). Given that typically only the principal investigator on a project sees any recongition, I think it's highly unethical.
I'm not sure what the scale is, but 12 mrem/hr is not 'normal' by any stretch. One of the detectors pictured was reading in microR/hr, which is more reasonable (at these levels, R approx== rem).
I don't think these lecture notes could be used in the same way that cliff notes are used to weasel out of reading a book. Class curricula vary widely, so you'd have a tough time learning the material just from online notes.
However, they could be quite helpful if you used them like cliff notes are supposed to be used--as a guide to help you understand tough concepts. Say you're learning about Kant's Ethics in philosophy class. Good luck getting the full meaning from the text itself, and your prof isn't too clear either. So, you go online, look up notes about Ethics, and get into an online discussion, then suddenly the concept of categorical imperative makes sense! I think it's a valuable study aid with little room for abuse.
As for your comments about studying--don't confuse cramming with studying. It's great that you're actively paying attention in class. However, you're going to start finding out in college, and even maybe when you get farther in high school, that your exams are going to cover not just the material from one chapter, but five or six over the course of a month or more. If you really want to know your stuff (and you will), then you're going to have to review it. Your recall after a month just won't be as good. Studying won't be a time intensive or stressful process (like cramming is) if you've been taking good notes all along. Also, while everything seems pretty obvious in ninth grade lab science, college organic chemistry may not come as easily. You're probably going to hear all these warnings from your teachers as you go through high school ("College is so much tougher than high school!") and some of them are blown out of proportion, but solid study skills really are an asset in college.

No, look in a CRC or google "electrical conductivty copper"
Aluminum is 38 / ohm-m, while copper is 60 / ohm-m. The difference is that copper is a much softer and more expensive.

The clip is actually made by a Brazilian electronica group called "Golden Shower."
