ELEMENTARY CHEMISTRY – Classic Science: Unit One: Chemistry 101

Build a Molecule

http://phet.colorado.edu/en/simulation/build-a-molecule

Age range: All

Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D!

 

Build an Atom

http://phet.colorado.edu/en/simulation/build-an-atom

Age range: All

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!

 

Isotopes and Atomic Mass

http://phet.colorado.edu/en/simulation/isotopes-and-atomic-mass

Age range: Advanced

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

 

What is nuclear?

Age range: All

What is nuclear? is a group of young nuclear engineers hoping to help the world learn some interesting and important information about nuclear power.  You will find a lot of information pertaining to nuclear energy on this site.

 

Atom Builder

Age range: Advanced

This advanced site will dig a little deeper than what you will find in the elementary Classic Science text.  However, if you want to explore the inner world of the atom, this site is a must.  Here’s a clip from their website:  “Here’s a chance for you to construct a carbon atom. You’ll start with a hydrogen atom, which contains one proton and one electron. Just add protons, neutrons, and electrons. By the way, you must also build each proton and neutron from two types of quarks — up quarks and down quarks. Finally, some advice: try to keep the particles’ charges balanced. You’ll have a difficult time if you don’t. ”

 

 

Scale of the Universe

Age range: All

This link is truly amazing!  With the ease of sliding a single bar across the screen you can get a virtual tour of the smallest known particles of matter up to the size of the universe.  I’ve included this link within the first unit for all of the textbooks.  It will put a lot of things into perspective for everyone.
