I've just finished reading the article, "Could Cell Phone Radiation Damage Our Brains?" by Regis Goode and Barbara Sitzman. The main topic of this article is that it is possible that when we talk on our cell phones and hold it up to our ears that the radiation it gives off could be damaging our brains. I already knew that cell phones gave off radiation and I also knew that over 2/3rds of kids over 7 have cell phones today. The third fact that I already knew was that large amounts of radiation such as this could cause skin cancer. One fact that I did not know was that there was a possibility that the radiation being given off by our cell phones could be affecting our brains. Two more facts that I did not know was that the amount of radiation a cell phone emits varies depending on the phone, and that cell phone manufacturing companies are required to list the amount of radiation a phone gives off but it does not vary very much between the different types of phones.

One thing I did not know is that mineral wool can be used to heat the flask and keep the heat under control. Something that is relevant to our class is the mixture and the distillation process because we just did a demonstration about that in class today. Something I found interesting is that instead of heating the flask with an open flame, you could just set it in hot water to make it boil.

Morgan, Yes the boiling point of some parts of crude oil is very low. 5 stars. MW

Some things that I already knew from this article was that particles of light are called photons and that Einstein won the Nobel Prize Award for physics and not his theory of relativity. Another fact that I already knew was that the amount of energy a wave has depends solely on its frequency. Some facts that I learned from this article was that there are three types of motion detectors and that the intensity of a wave depends on how many photons there are, and not how much energy each one posesses. The last fact that I learned was that the human eye is like a photo sensor that reacts chemically and sends signals to the brain based on different movements.

Morgan, Yes the "miracle of sight" is actually based upon a chemical reaction. Good thoughts! 5 stars. MW
