I liked the first graphic better, because it is easier to use when you are trying to decide what something is. If you can answer yes to the question then you move down the chain. On the other hand if you can say no to a question, you look to the right and it tells you what it is. So this makes it easier because you have questions to ask yourself about the thing you want to find out about. The other thing that i like about the first graphic is, that there are pictures that show you how a compound, mixture, or element would look like. The reason i didnt like the second and third graphics, were because they were in tree form. The second graphic was not very descriptive, but the third graphic was descriptive and even gave examples.

In Mrs. Rafferty's Biology class last year, we did the same thing with the chromatography except we did it with pens. We made dots on the paper and then let the water soak up the membrane and you could see that certain pens had more color than others. This is relevant to class today because we separated the colors of the Skittles and M&M's, and we used the exact same process as before. Also the cops us this technique to tell if a certain pen was used to write a ransom note, or if it was the murder weapon.

In soccer there are things called direct kicks. A team gets a direct kick if someone on their team is fouled. When you take a direct kick, you try to get the ball in the goal, but the other team is aloud to put a wall of people 10 yards in front of the shot. If the ref miss measures, he could give an advantage to either team. If the walls too close, its unfair for the person kicking the ball, but too far away and the other team is not close enough to even have a chance of blocking a shot. So this shows how measurement plays an important part in my life.

Gilbert, Good thoughts! MW

Something that intrigued me was the seven base units because in truth i had only heard of meter, kilogram, and seconds. The others which include candela, mole, kelvin, and ampere and we are learning about these in class which is really cool. The other thing i think is alittle weird but interesting is the fact that even though they have copies they wont let you touch the kilogram that is in%2Proxy-Connection: keep-alive Cache-Control: max-age=0 aris. I guess that like the cave rocks in penn cavern that your not supposed to touch, because the oils will eat away at it.

Something that I learned from this article, is that now instead of just using one x-ray machine, they will be using multiple. This makes me feel extra safe, because that greatly reduces the chance of something slipping through. Something that i found interesting, is that there are so many videos online, that tell people how to make bombs and these bombs could be used to help the next terrorist attack. Although it is interesting, it is also very sad and disturbing. Lastly, something that would relate to class is, that when i went through security, the man in front of me was a metal rod in his leg, so he was a definite to go off, but luckily he had his card, and after a few checks he was sent along his way.

Mason, Good. 5 stars. MW

Something that I found very interesting in the Mole website was the date of Mole day. It is from 6:02am to 6:02pm on 10/23. I think this is really cool because it helps me to remember the formula for finding a mole, 6.02X10^23. Another thing that was interesting was the fact that when saying the pledge to the mole, a real mole is usually not present. So, one should bend over and face the earth!

Mason, Funny but a little short. Any science stuff? 4 stars

Dust Explosions What I found interesting about the article is the fact that there is only a very small amount dust needed to be on the floor to be called explosive. This is scary for me because my brother works in a shop that constantly has dust on the ground, and i don't want the dust to cumbust and hurt anyone in the shop, especially my brother. Stoichiometry is super important because you have to know the ratios of a certain object to that of another object. If you do not know the mass or volume it could cause an explosion. If you know this skill it can help you out in more ways than just this one.

Mason, Good thoughts once more! 5 stars.

Sulfur Hexafluride I found it very interesting that you can breath in the gas without causing a reaction with your blood and everything else, even though what makes it are two very reactive elements. Flourine is one of the most active no metals that there are. I like how it makes your voice so Mr. Washington like but you have to breath deeply to get it out. Also that it feels like water is in the ballon because of how heavy it is.

Mason, Real latwe with this one! 3 stars.

Motion Detectors I learned from this article that there are 3 different types of motion detectors. I knew about the radar one, because mythbusters tried to sneak by one (it worked). But i didnt know about the temperature related detector which senses temperature differences in the room, or the one that uses a light source which when blocked tells the sensor something is in the room. The bathrooms in our school have them so that the lights come on when you walk in...if you lay on the ground and slowly slide you can get by them. I swear!

Funny! MW
