A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

In this equilibrium learning exercise, students solve nine problems related to acids, bases, buffers, ionization and calculations of pH.

Balancing equations is a foundational skill for starting chemists. There are a few slides in this PowerPoint with colorful diagrams that help to explain how. Unfortunately, the presentation begins with an unrelated table of contents and...

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

In this chemistry worksheet, students learn about matter, including atoms, electrons, protons, neutrons, compounds and chemical properties. They use this information to answer the 10 questions on the worksheet. The answers are on the...

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.
