U.S. Towns and Elements All over the united states of America there are towns that have names that are also the names of the elements on the periodic table of elements. Some things that I do know about this is that there are many ways that the elements got their names from the town. I also know that the towns usually got their names form the people that founded the towns. I also know that the towns were founded very long ago. I learned that in Texas there is the town named Gold that was founded by two German brothers, but then they died. Another thing I learned is that Iron Minnesota was one of the first towns to start mining iron. A final thing I learned was Lead South Dakota was founded shortly after the finding of gold. The towns of the United States have very similar names of the elements, which is very cool!

Jay, Cool post! :) I'm glad you found some interesting stuff! 5 stars! MW

Distillation- This was a great learning experience. The way the lab was set up with all the tubes was very nifty to me. I learned how the different liquids all have different boiling temperatures. It is also nice to see that the little lab that they used in the begging of the movie was then used later but on to a much bigger scale in a real life situation. Because most of the time with things we do in school are never used in real life. So when you see that your work can one day be used in the real world is very interesting. And that's what i found nice in this video.

Jay, Well it is real life just not on a large scale! A little sparse on the scientific side. :) 4 stars. MW

Motion Detectors I already knew a few things that have to deal with motion detectors. For one I know that they help us in life with opening doors. For example when you go to the store and your cart signals the door to open. I also know that motion detectors are used to keep a garage doors from closing on you or a bike (any object) because when something crosses the area where the beam is between the two detecters it signals the garage door to stop moving and go back to the top. Another thing I knew was that when you are walking by someone's house at night a big bright light will shine when the motion detector knows your there. Now for some things I learned. I never knew that there are 3 different kinds of motion detectors that all work differently. I also never knew that the way motion detectors are also what animals use to catch prey. Such as the bat that sends out sound signals and when the signals bounce back to him he knows where everything is, even though it is pitch black outside! Another thing I learned is that certain things set off certain motion detectors. Like one type of motion detector might sense something is coming towards it, and an other one will only sense the presents of a human being. These facts are all very interesting and fun to learn!

Jay, Well done! You obviously picked up some good info! 5 stars! MW
