Atomic Structure and Quantum Theory

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements, this...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having students drop a pencil on a sheet of...

Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use. 

How are atoms structured? Viewers of the video first learn about atoms and atomic structure, including the nucleus and electron shells. The video then describes how atomic numbers and atomic masses are expressed on atomic symbols. You'll...

Explanation of advanced atomic theory using The Schrodinger equation.

An introduction to the mole, a unit of measurement that quantifies atoms and molecules.

"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...

Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

When we take things apart, we can learn how they work. Physicist Clifford Johnson explains how we break down all objects into elementary particles of matter and forces. Patterns have been identified with the particles, the existence dark...
