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have been replaced by other Carbon, Hydrogen, Oxygen atoms that you have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 in 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.
