We spent this week immersed in the anatomy of the atom. But have you ever wondered about the atoms that are in your anatomy? Your body is composed of a huge number of atoms, all working together to make biological molecules that, when put together in just the right way, make you into a living-breathing person. Where do all those atoms come from? It is interesting to consider that nearly all the atoms that are in your body get replaced every year. So, in essence, you're literally not the person you were just last year because all of your atoms have been replaced by other Carbon, Hydrogen, Oxygen atoms that you have ingested or inhaled or rubbed up against.
Take a look at this cool video I found that illustrates the connections you have with the stars.

I gave you a brief introduction to the periodic table using ptable.com (my favorite website). Who can help but be inspired by the layers of information contained in this chemistry icon. A friend of mine sent me the link for a fun iPad app called Nova Elements. You can play a game called Essential Elements where you build atoms and molecules of common substances from subatomic particles (protons, neutrons, and electrons). There's another awesome interactive periodic table to explore on the app too. You'll also find a video, that I must confess I haven't watched yet. Take a look if you have an iPad. (it's a free app!)

Let me know what you think about the video, the app, or another interesting site you have found related to the atom or the periodic table. Or, you can post your favorite element and why.
