The Molecular Workbench Database: Models of the Atom's Electron Orbitals
Learn about atomic structure and the multiple theories of atomic structure in this simulation.
Texas Instruments
Texas Instruments: The History Behind the Atom
This StudyCard activity enables students to review the key contributions by scientists and philosophers towards are current understanding of the atom. It also allows students to review characteristics of the major atomic models.

Concord Consortium: How Does an Object Become Charged?
Activity 2 in this module examines How do objects become charged? An investigation of where the electrons come from and where they go, when atoms become charged.
Concord Consortium
Concord Consortium: What Are Nature's Building Blocks?
Activity 1 of this module explores What are the particles that make up all substances, and how small are they? A history of the atom is included.

The Atom's Family: The Phantom's Portrait Parlor
In this activity, students investigate the atomic world by attempting to reduce paper to the size of an atom. Although students won't be able to cut the paper that small, they will gain a better understanding of how small the atom is.
