Cyanide, a coordination compound, is used in the extraction of gold and silver. Part 24 in the series of 36 delves into the world of coordination compounds. Classes learn, through readings, discussions, and answering questions, how to...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

In this chemistry worksheet, students examine the oxidation state in order to apply it in the laboratory setting. The sheet includes in depth background information.

In this chemistry worksheet, students find the outcomes necessary for the oxidation reduction reactions. The sheet includes background information.

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

After giving the definitions of the different compound terms and formulas, equations are provided to teach your chemists to calculate different values. Relative formula mass, atomic mass, and empirical mass are shown and explained with...

In this crystals worksheet, students complete a graphic organizer by filling in the characteristics of the different crystal types including melting/boiling point and electrical conductivity.

Pupils explain the mole concept and use this concept to prepare chemical solutions of particular molarities.

In this chemistry worksheet, students examine the energy rule of moles and answer the essay questions. The answers are include with the worksheet.

Seventh graders distinguish between physical and chemical changes in both natural and technological settings. They identify the reactants and products for a given chemical reaction. they then write simple chemical equations given the...

In this stoichiometry worksheet, students identify types of reactions, show the products, and balance the equations. Students determine the limiting reagent, theoretical yield, and percent yield for given reactions. This worksheet has 5...

Students practice naming and writing formulas for simple chemicals. After a review of vocabulary, they create ion flash cards and discuss the rules for writing chemical compounds. They practice naming and writing the formulas based on...

For this word search worksheet, students search for 32 hidden words found vertically, horizontally, backwards or diagonally. Words are words encountered during visits to "The Jefferson Labs."

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

In this intermolecular forces worksheet, students read about the two types of forces: dispersion forces and dipole-dipole forces. Students then complete 2 problems based on what they read.

Students investigate temperature and chemical reactions. They explore the effect of temperature and particle size has on the rate of a simple chemical reaction. In addition, they graph their results and answer assessment questions.

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...
