I think the second graphic puts out more information and is more appealing. It has the same information as the first one but it is in a more confined space. It is also better colored than the first one. The first one has pictures, which I like, but it has a little bit less information than the second. They both are good graphics though.

I didn't know that the dyes in foods could be seperated. I wonder if you could do the same for fabric. I also would like to know what is in the paper that makes the dyes seperate. I want to know how or if you can seperate the dyes called "lakes".

Kenny, Good question on the "lakes". Your post is a bit short though. Please check the rubric. MW

Measurement is very important in everyones lives. One example would be cooking. One time my dad put too much red pepper in recipe, this was not a good idea because the food was so hot that even he couldn't eat it. Also In my drafting class measuring is very important. Lets say you were desiging a replacement part for a machine. if it didn't fit by even a fraction of an inch the machine might not function right.

Funny and a good point. MW

In the article "Redifining the Kilogram" I found it interesting to know that there is a real kilogram that is the standard. I wonder what would happen if it got damaged in any way? Would they have to redo the entire mass standard measurement. I think it would be a good idea to make standard out of a material that will not change. I think it is needed because the article said the standard now is already changing and it is not that old.

The article about airport safety is scary and reasuring at the same time. It is scary to know that people are trying to kill many inocent lives. But it is reasuring to know that many people are involved in tring to stop a disaster like 9/11 from happening again. I would like to know how X-ray machines can detect things like density and mass of things. It does all of that in very little amount of time, almost instantly. That is amasing to me.

National mole day is celebrated on october 23 from 6:02 am to 6:02 pm. It is after the number 6.02x10^23. Amadeo Avogadro first discovered the number but he didn't receive credit until after his death in 1858. A mole of an element is equal to the elements atomic number in grams. So a mole of carbon is 12.00 grams. The mole is based off of the element carbon

I found it very interesting that dust could create an explosion that big. It was suprising that factories can have as much as half an inch of dust on the floor. It did make sense that more dust gets shaken loose after the initial explosion. Then this dust could would catch fire and make a bigger explosion. I wonder how many moles of dust there was in the sugar plant. What would the chemical formula of dust be? Kenny, A little light on stoichiometry. 4 stars.

The article on sulfur hexafluoride was very interesting. The gas is very heavy because in it there is 6 fluoride and 1 sulfur atoms. Both of the elements are not good for you by themselves. Sulfur is used in gun powder and fluoride is the most reactive nonmetal. The two of them form a compound that is so stable that you can inhale the gas. It makes your voice deep.

Kenny, A little short on length and content. 4 stars. MW

The article on motion detectors was very insightful and interesting. There is 3 kinds of motion detectors. One is the kind that uses radio or microwaves to bounce of of an object and sent a signal back whether there is an object there or not. This is similar to dolphins sonar and radar the police us to catch speeders. A second kind is able to "see" an object based on the infared waves all warm blooded animals give of in the form of heat. The third kind senses an object when it breaks a beam of light that then bounces back to the sensor.

Kenny, OK. MW
