I thought the first graphic was helpful because it also showed pictures, as well as the classifications of matter. I also liked it because it asks specific questions, so that if you were confused about the classifications, you can just follow the arrows. The second graphic doesn't include solutions, just homogeneous mixtures. It is very easy to read, though, so if you know what you're talking about, this would be a good graphic. The third graphic gives specific examples, which makes it simple to visualize the different classifications. Overall, I like the first graphic the best because it asks questions. It makes it uncomplicated to classify matter.

Before watching this video, I didn't understand distillation. I now understand that distillation is when you boil a mixture, and the result is your distillate. What is left over from the mixture is a residue. For example, if you were to distill salt water, the water would be your distillate, and the salt would be the left overs. The same process is used to make moonshine. The distillate would be the alcohol. However, this process is illegal.

Measurement is important to me in my life if I'm cooking. Following the recipe is essential, which includes measuring the ingredients correctly. Not only does this include making sure there's enough chocolate in the chocolate chip cookies, but also something as simple as adding enough yeast to the bread to make sure it rises. The same goes for baking soda and baking powder. Messing up these fundamental ingredients could completely mess up your whole concoction.

Steph, Good point!! Cooking and chemistry are well linked.

For at least a hundred years, an official kilogram has been ratified and accepted as the constant for mass. Now, it is one of the last of the seven base units of the International System of Units, and is kept in a vault with six copies at International Bureau&%Proxy-Connection: keep-alive Cache-Control: max-age=0 %Proxy-Connection: keep-alive Cache-Control: max-age=0 %Proxy-Connection: keep-alive Cache-Control: max-age=0 %Proxy-Connection: keep-alive Cache-Control: max-age=0 nbspProxy-Connection: keep-alive Cache-Control: max-age=0 B Weights and Measure near Paris. However, over time it has lost its accuracy, and the solutions include assigning an exact value to Planck's constant or to Avogadro's constant. Both are favored by different scientific fields.

Airline Security has a lot of responsibility, insuring that you will be safe when you fly. Luckily for us, they're doing all they can to prevent attacks, which not only come in forms of regular old knives, but also bombs and other firearms. They also have to look out for different components of a homemade bomb, as anyone can simply create one with online video tutorials. Ways TSA officials use to check for weapons include intense x-ray beams, measuring the density of the item, which they can then compare to values for explosives.

Mole day is celebrated from 6:02 am to 6:02 pm on October 23. Apparently it is a pretty big deal for those who know what the mole is, as there are websites, theme songs, crafts, and even t-shirts. The mole is a number that represents grams that is equal to the atomic mass of the molecule. This was discovered by Amadeo Avogadro, but he didn't receive credit until after he died. My favorite part of the

Dust explosions unroll in waves and last January in Georgia that is what happened to a sugar plant. The sugar dust in the air caught fire, and from there a chain reaction takes place, exploding and spreading the fire everywhere. The subsequent explosions are usually worse than the initial explosion. Nine workers died and sixteen were seriously injured and now the CSB and OSHA continue their debate on plants that generate combustible dust should be regulated.

Sulfur hexafluoride is a gas that makes one’s voice lower instead of higher, like helium. This can be dangerous, however, not only because of impurities the tank may contain, but also because of the lack of oxygen. One realizes it needs oxygen by the carbon dioxide buildup in the bloodstream, but when one breathes out the carbon dioxide and breathes in sulfur hexafluoride, the call for oxygen isn’t present. Also interesting is the fact that when sulfur hexafluoride is captured in a balloon, the balloon gets bigger, because the rate of air traveling in is greater than the rate of sulfur hexafluoride escaping out.

Motion detectors have three main methods to detecting movement. The first is where an infrared light is aimed at a photo sensor. When the beam of light is interrupted, the motion detector knows that something is there. Second, is the machine can send out waves, from radio to microwave, and can tell when something has arrived when the pattern changes. Lastly, motion detectors can detect movement by monitoring the infrared radiation coming in, or the warmth given off by animals.
