What i learned was that there are some pretty interesting things about some of the towns. For example, i liked that there was a town called Nitrate, Montana that is just cool. Also i thought that Boron, CA was cool because i don't think that Boron is boring.

Redefining the Kilogram

I thought that the article and our discussion were both interesting. For example, they might get rid of the kilogram completely which is, i think the best decision. The reason being that it isn't truly a kilogram. That one machine they are using will be a much better way to get another object that is 1 kilogram. The Mvp of this would be that that one piece of metal weighed exactly one kilogram not 1.0000000001 but exactly one. lastly, one other point i found interesting was that they actually kept it under lock and key it must be priceless.

Michael, I think you could safely say that it is indeed priceless. I don't think even Bill Gates could buy it! 5 stars. MW

Motion Detectors

First off, one thing i already knew about some of the motion detectors it that they transmit radio waves and if they come back to the detector in a different pattern it will set off the motion detector. Additionally, i already knew that bats use echolocation to find their prey and determine where it is heading and what types of insect it is. Lastly, i knew that you couldn't trigger a motion detector when your outside and its inside even if you pass it. However, i learned that some motion detectors use infrared and whenever something abnormal goes by it triggers, I thought was pretty cool. Also i thought it was neat how some motion detectors use light instead of infrared. Finally, that some motion detectors can use sound to go off and if the sound comes back to them too soon they go off. I thought that was the most interesting thing. In conclusion, the science behind motion detectors is really interesting once you get to know it.

Where do elements come from?

Elements form in stars, when these stars explode they release elements across the universe. Hydrogen leads to most elements. Interstellar clouds formed planets and stars.

Sugar Explosion

I found it very interesting that sugar when ground up can explode like that in the air. It's a very common household item. I also thought it interesting that other things could ignite when they are dust. For example, wood, plastics, metal, flour, and coal. I can tell you what jobs I wouldn't want to have when I'm older. Lastly, didn't Mr. Williams try to use sugar as a substitute for likapodium powder and try to force it through a Bunsen burner.

Michael, Yes I did. A little sparse but OK. 5 stars. MW

Helium balloon

I found this article very interesting. Especially, considering the fact that in a vacuum you weigh .2 pounds more that you would on Earth. Also I already knew that the air got less dense the farther you got up. And the more outward pressure there is that is why balloons pop when they get too high up into the sky. And of course the helium balloons float because the are less dense than the air

Michael, You really didn't follow the prompt on VIP's and MVP. 4 stars. MW
