I really enjoyed this article. I think it's very interesting that humans give off infrared radiation - the concept blows my mind. I never had any idea that motion detectors had to be so complex. I guess we don't consider all the "workings" that go on in everyday life. It's pretty crazy to that electrons have SO much influence on our world as it is today. In fact without them there wouldn't even be a world, so I'm very thankful for them. To be honest, the world is so complex that even we can't understand it all but it's fun to learn things like this where we get a glimpse at it. Paige, Yes the world is a complicated place. It's our job as scientists to make some sense of it all! MW

I found this article quite interesting. It seems as though Sulfur Hexaflouride is not a gas to be messed with. The fact that is expands in a balloon helped me to further understand the concepts that we discussed in class today. I now can see an example of a very heavy or dense gas and how it reacts in comparison to a less dense gas. The thing that really captured my influence was the statement about people who suffocate while breathing helium and the like. I never considered that you were suffocating yourself due to lack of oxygen.

Paige, Good post but what do you mean by "captured my influence"? :) MW Mr W, I meant interest. :) PK.

From this article, I learned quite a few things. For one, I learned that common household products, such as sugar, can end in terribly explosive reactions. I had no idea such reactions could take place by such a small spark. It's very tragic that so many people were injured and/or died from this accident. It just goes to show you how powerful the natural reactions of the world can be. Stoichiometic relationships are important to reactions because it can cause these otherwise harmless materials to be apart of a dangerous reaction if the relationship is correct.

Each of these organizers does a good job in showing the Classification of Matter, however I prefer the first graphic before the other two. However, there are benefits to all three. While the second organizer is very simple and easy to follow, the first includes image examples of each phase. The second and third are both in the form of a “tree” organizer, while the first is more of a flow chart. Although each organizer is effective, I prefer the first because it displays how to determine what each of the types of matter is truly classified as.

Today, while discussing the separation of matter, I learned a few new facts. First of all, I did not realize that distillation was such a complicated process. However, the diagram we saw really helped me see how it works and why it is complex. I also realized how often we use filtration in our every day lives. It is a very convenient process, because it allows us to drink clean water. I find this topic very interesting.

Measurement definitely plays a key role in many aspects of my life. For example, the doctor provides us with quite a few crucial measurements. Blood pressure, height, weight, heart rate, and cholesterol are all very important. If these measurements are off, it could seriously throw off a person's health status, and in extreme examples, could cause death. Another area that measurements are important is baking and cooking. Ingredients need to be exact in order to end with the desired product. Paige, Good angle to take. Lots of things are measured in the name of health! MW

One interesting thing that I discovered about the kilogram through reading this article was that it is the last unit that is measured in comparison to a real object. This is interesting to me because it shows that they have a baseline for what a "gram" actually is. I also learned that the baseline is slowly losing weight. This to me seems like a bad thing because obviously everything is based around this one measurement. I wonder if the baseline changes, will all other measurements shift to fit with this "new" Proxy-Connection: keep-alive Cache-Control: max-age=0 ight?

I found this article%2Proxy-Connection: keep-alive Cache-Control: max-age=0 o be very interesting. I fly quite often, and I never knew that the security scans did anything more than take an xray snap shot of the baggage. I was shocked to hear that density plays a key role in determining a bomb! What would happen if someone discovered how to get around this system? Although I doubt this will happen, it is something to think about. My parent's bags have sometimes been stopped and checked in the security line, and we always found it to be such a pain. But, then we remember it is all for the good of our safety.

I am excited for Mole Day. It's better than Pie Day, I'd say. From the website, I learned some pretty witty Mole jokes, and also got to read the "Mole Pledge". I also discovered that Avogadro was the one who originally came up with the concept of the mole. I think that we should celebrate mole day in class, because it's relevant to our unit right now. I also got to learn that the mole is a very highly loved unit of measurement in the Chemistry community. I would have never known that October 23rd was so significant.
