AT: Atoms Learning Targets

Core Vocabulary:

Interactive Activities:
  • Introduction to the Atom
    In this interactive activity from ChemThink, learn about atomic structure. Follow the tutorial to understand how individual atoms—the basis of all matter—are composed of subatomic particles such as electrons, protons, and neutrons. Investigate the three types of particles, their properties (such as mass and charge), and relative locations. 
  • Another Introduction to the Atom
    This interactive activity, from, focuses a bit more on the electromagnetic charges within an atom.
  • Build an Atom Java Activity

Interesting videos:
  • Atoms: The Space Between
    You wouldn't know it to look at it, but the atoms that make up a solid piece of iron contain more space than stuff. How is it then that the whole world doesn't just crumble around us? This video segment adapted from A Science Odyssey uses models, vivid descriptions, and analogies to explain the structural integrity of matter at the atomic level. 
  • Vsauce: You Can't Touch Anything
    A terrific video (suggested to me by Andrew C.) that helps to explain why you can never really touch anything!
  • Just how small is an atom? This small!
    An amazing TED video that explains just how small an atom really is, and just how dense the nucleus is. Prepare to be amazed...
