Uen: Where Did the Matter in the Universe Come From?
Students use various articles about how atoms are made and spread throughout the universe starting with the Big Bang. They will study the articles as groups and will then present their information to the class.

Ted: Ted Ed: The 2400 Year Search for the Atom
How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

Atoms in Motion: All Matter Is Made of Atoms
Atoms are very, very small. Atoms are so small that it is often said that there are as many atoms in a single grain of sand as there are grains of sand on all of the world's beaches - certainly a difficult thing to prove, but you get the...
