The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general...

The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to...

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

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...

What a cute approach to chemical bonding! Atoms all have human names and are attending at a dance. Who will pair up with whom? By reading the characteristics, and not the element name, chemistry whizzes figure out the bonding pairs....

Introduce emerging engineers to the process of metal plating. This resource provides background reading on chemical engineering, plating, and corrosion. It concludes with a copper plating activity. The standards alignment list includes...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...

Emerging chemists find their calling as they calculate the concentration of hydronium and hydroxide ions and the pH and pOH for several solutions. In some cases, values are given, and in others, actual word problems are written out....

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Here is an attractive worksheet that walks chemistry learners through a review of aqueous solutions. There are matching, short answer, and multiple choice questions dealing with boiling and freezing points, precipitate, molality, net...

In a single-page ionization worksheet, upcoming chemists determine the molar concentration and ion product constant for water. They practice writing dissociation equations and determine the OH- and H+ for each solution. This constructive...

Here is a top-notch handout to supply your chemistry class with. It covers valence electrons, Lewis diagrams, the octet rule, and more! Technically it is less of a instructional activity than a detailed explanation of these chemical...

Chemistry students review the trends found in the organization of the periodic table by completing this worksheet. They determine which of the given atoms has the largest ionic radius and which is the most electronegative. This worksheet...

Biochemistry scholars will be well prepared for an exam on biomolecules after completing this concise assignment! There are 75 short-answer questions about the chemical makeup, functions, and relationships between organic molecules....

Newbies to chemistry will be enriched when completing this worksheet. It gets them to explain the subatomic particles and their charges, ions, and valence electrons. On the second page they complete a chart of the numbers of protons,...

A more thorough PowerPoint on chemical bonds and chemical reactions would be hard to find! Through 108 slides, chemistry learners are taught about how compounds are formed, how to name them, and how to balance chemical equations. They...

A chemistry lab activity where inquisitors demonstrate Le Chatelier's principle by combining aqueous solutions and making observations of the physical changes that occur. The changes indicate a shift in equilibrium. There is a concise...

This is an apt assignment for chemistry takers that are studying ionic solutions. Eight questions require problem solving and critical thinking to answer. The first question instructs learners to use a table in the textbook, but you can...

All you will find in this resource is a list of vocabulary terms dealing with chemical bonds. Space is provided for chemistry learners to write out definitions. This would be a terrific tool to help prepare them for a quiz.

Here is a thorough review of chemical bonding! Seventeen problems query chemistry learners about electron configuration and ionic bonding, sharing electrons and covalent bonding. Chemistry masters draw Lewis dot diagrams and answer...

The first four of these six pages query advanced biology learners all about bacteria. Different reproductive means, life cycles, symbioses, and methods of genetic diversity are addressed. Questions consist of short answer type and...
