Hunting the Elements

Think of the Past:

Before watching "Hunting the Elements" in class, I knew only a limited amount of things about the periodic table of elements. One of the things I knew was how the table was arranged. There are these things called groups and periods that organize the periodic table. Groups are the columns, while the periods are the rows. For example, Titanium is in Group 4, Period 4. Another thing I knew was the number of elements on the periodic table, which is 118. 

Think of the Present:

One thing that I learned from watching the video is how important bronze is in history and what it is made of. To start, bronze is the first man made mental alloy. Additionally, bronze played a major role in an entire age of human civilization. Bronze is made of copper and tin. Adding tin to bronze changes the properties of it. Tin also helps bronze stay stiff and sturdy. 

Think of the Future:

I found the "nuclear section" of the video very interesting and cool. One element that stood out to me was plutonium. I would like to research more about it and its properties, as well as who discovered it. Another reason that I would want to research plutonium is because plutonium was used in the movie "Back to the Future". Plutonium was used to power the Delorean and the flux capacitor, the thing that makes it travel in time. The only problem was that plutonium was hard to find and the time machine used up a lot of plutonium every time it time traveled.
