I enjoyed reading this article about how many different chemicals can be used for murder. When one first think about it,they wouldn't think of as many chemicals that can easily lead to someone's death. But this article shows that with the right amount, many chemicals can be dangerous. The story that I found most intriguing in the article was the story about a man who poisoned his wife by poisoning a water bottle, and he tried covering it up by poisoning other water bottles that the store was selling. It amazes me how far a person will go to try and cover up illegal actions. When you think about it, others would have died as well because they would have bought poisoned drinks.

Hannah, Yes it really is amazing how poisonous some substances can be! Scary really. Good post! 5 stars. MW

I thought it was really interesting reading about trick candles. I've never used them for my birthday, but watched others. They were always interesting, but I didn't really think about the science involved. This article taught me that using magnesium was what was used to relight the flame. Just a little bit of it, and a new flame will appear because of the leftover embers. In the article, there was a mention about a colored flame, and it reminded me of fireworks. Fireworks is, in simple terms, colored lights; that's what a candle is. Even though the science is there yet for colored flames, it could be possible. Maybe if you apply the idea of a firework into the solution, something will come out of it. But it has to be safe first, don't want any fires starting:-o.

There were three things that I found interesting in this article. This first was in the very beginning when it was stated that scientists have spent spent the past four centuries discovering the truth about how the world (naturally) works. I found this interesting because four centuries is a long time to find the truth. If it took that long to try and discover it, though it still isn't defined, then the natural world is very complicated and the truth might take even longer to be discovered. The article stated that the prototype for the official kilogram is kept in a vault outside of Paris; along with having six other copies locked away. This surprised me a little because f how big a deal scientists are making the official kilogram. It makes you think that if something like the official kilogram is locked away, then it must be really important. The third thing that I found interesting was that a change in the kilogram would make Avogadro's number and the mole would be really meaningful to mostly metrologists. This seems like a small number of people, but their job is the study of measuring. Their job is important, and to me, can affect many different outcomes of things. It might even affect us in a way. According to the article, the small change can make learning easier for students, so that affects me directly.

Hannah, Well done. You followed the prompt extremely well. I guess we can see how important it is for people to try to make a stable and predictable world out of this chaos! :) 5 huge stars! MW

I never really thought about the science behind motion detectors and how many there are. The article mentions that light is a big part for sensors because then, electrons are ejected. No one would really think about how sensors that use light work, only what their main purpose is. What I also found interesting was the fact that animals have sensors that help them hunt. An example could be a rattlesnake. These animals have sensors called pits that can detect infrared light. These snakes can then be able to detect their next meal. Another situation with detection deals with a shopkeeper and a bell ringing when customers enter and leave the shop. The article states that light is being broken by the person/object. It is interesting to know that a ray of light that is being broken causes a ringing noise that tells the shopkeeper that they have a customer. It is kind of cool to think about that kind of stuff.

Hannah, I see you have a genuine appreciation for motion detectors! Good post. 5 stars! MW
