As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Challenge young scholars' understanding of thermochemistry with this skills-practice worksheet on Hess's Law. Given a series of five multi-step chemical reactions, students must determine the overall change in entropy...

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...

An overview of acid and base compounds and their reactions is presented with this handout. Pupils name compounds and write chemical formulas. They write net ionic equations and explain how acidic solutions might conduct electricity. This...

In this formula for magnesium oxide worksheet, high schoolers perform an oxidation reaction between magnesium and the oxygen in the air to produce magnesium oxide. Using the known masses of the magnesium and the end product, students...

In this nomenclature instructional activity, students are given twenty-eight compounds to write the formulas for and they are given twenty eight formulas to name. The compounds include covalent compounds, ionic compounds and acids.

In this compounds instructional activity, students write the correct name of the chemical formulas given and write chemical formulas for the given compound names. This instructional activity has 42 problems to solve.

In this solubility activity, students characterize compounds as either soluble, slightly soluble, or insoluble. Then students write the chemical formula for each compound. This activity has 10 problems to solve.

Here is an interesting activity which invites learners to focus on understanding and interpreting the symbols used in writing and communicating information about chemical elements, compounds, and equations. The hope is that this...

In this compounds worksheet, students name the given compounds from its chemical formulas and write the chemical formula from the compound name. This worksheet has

In this chemistry worksheet, students practice forming the correct chemical equations for the twelve problems presented. The second page has the answers.

In this water learning exercise, students compare and contrast elements and compounds. Students define chemical symbols, chemical formulas, and chemical properties. This learning exercise has 19 short answer questions.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...
