The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for a...

Lead the class on an investigation as they play detective and locate patterns in the electron arrangement of atoms. During the seventh lesson, they assign valence numbers to elements, organize the periodic table in the correct sequence,...

Does anyone remember seeing the movie Fantastic Voyage? This app is reminiscent of that imaginary journey through the human body, but in this case, venture even further into individual cells!

As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to the Earth. This page looks at the Earth and its lithosphere, the chemical composition of the Earth, the structure of the Earth, and more.

Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...

This is an online exercise in which chemistry learners answer a series of multiple choice questions about bonding. Topics addressed include ionic and covalent bonds, electronegativity, ions, valence electrons, resonance structure, and...

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Two men want drinks and the first orders H2O. The second man orders H2O too, but he dies. Scholars apply their knowledge of H2O2 and other everyday chemicals during the activity. They match chemical formulas to common chemical names in a...

What is space made of? It turns out that there are many compounds found in space! The 10th lesson of a science series provides a list of the compounds found in space and asks young scholars to research the characteristics of these...

"The name is Bond. James Bond." Or is that "Chemical Bond?" Assign the viewing of the video as homework, and then have your chemists come to class to practice drawing electron dot diagrams and Lewis structures with the several bonus...
