A tutorial that explores the concepts of heat and temperature, the transfer of energy between substances, the relationship of temperature and the movement of atom, and thermal radiation. The tutorial includes animations, interactive...

This is an excellent site with information on the discovery of the atom and the different models. Includes a sample question and answer using Planck's constant.

Simulations to show students the nature of chemical bonds. Simulations include an explanation of stereochemistry, atomic orbitals, chemical polarity, formation of an atom, and a summary quiz.

A simple dialogue to explain quantum theory and the Schrodinger equation. Includes several java applets.

Observe the motion of this animated system to represent an analogy for molecular mechanics of atoms and molecules.

Learn to re-model your lesson plans to include room for critical thought and higher levels of learning. Re-modeled lessons cite specific critical thinking strategies. Wonderful examples include " Writing Haiku," "Myths," "Sojourner...

This tutorial will help students understand how Dalton, Thomson, and Rutherford contributed to the model of the atom.

Students draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.

Students will use pennies to model the half-life of radioactive atoms.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will explain the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. They will also...
