10/5/11: I already knew that on type of motion dectecter uses sensors that are sometimes infared. I did not know that photo sensor means anything that sensors light and it invariably depends on lights capacity for pushing around electrons. The secont thing I already knew was that Einstein came up with the theory of relativity. The second thing I did not know was that the eye is a type of photo sensor. The third thing that I already knew was that some sensors are broken by an object crossing through the them. An example would be an elavator. The third thing that I learned was that it is the individual particle energy that matters when it comes to the photoeletric effect.

Adam, OK. Looks like you picked out some good items from the article. 5 stars. Please check your spelling. MW

Video 9/19/11: I learned that during the process of distillation the crude oil is heated in hot water and not an open flame. Also that the lower boiling point collects at the top because it turns into a gas quicker. This has a relation to our class because we used the distillation technique that they used with the oil. We used the copper sulfate and water. Overall I think distillation is pretty cool because you can get the mixture to com out clean if you do it right.

Adam, Right! Purifying chemicals that come from nature is a very important advancement. 5 stars. MW

The first thing that I learned from the article about artificial blood was that hemoglobin means the key oxygen binds protein in blood. One thing that I already knew was the military supports the research for blood substitution. The second thing that I learned from this article is that blood donations only have 28 days in storage and it has to be kept cold. The second thing that I already knew was blood can carry HIV from one persons blood to the other. The third thing that I already knew was that red blood cells play the most important role in the body. They transport oxygen throughout the body. The last thing that I learned from this article is that oxygen conduit is the protein hemoglobin is used as an oxygen carrier in many blood substitutes.

Adam,

OK. Looks good! You picked up some great info from this article. 5 stars. MW
