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...

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...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

In these atomic mass review worksheets students will complete formulated questions. Students will answer 17 problems on atomic masses to review the chapter material.

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Here is a straightforward practice test for first year chemistry learners. Responders balance equations, identify types of reactions, represent electron configurations, and solve stoichiometry problems. Keep this handy to use as...

Plenty of time was invested in creating this detailed presentation. The first slide alone includes several steps that support your explanation of percent composition, a precursor to understanding how to write empirical and molecular...

Learners investigate how to determine the percent composition of a mineral in an ore. For this mining an ore lesson plan, students use chocolate chips cookies to represent an ore and they remove precious minerals (the chocolate chips)...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

Students determine the molar volume of hydrogen gas. In this molar volume lesson plan, students find the molar volume of hydrogen produced in a reaction between magnesium and hydrochloric acid. They use a eudiometer to measure the volume...

In this molarity worksheet, students fill in unknowns such as mass of solute, moles of solute, volume of solution and molarity of solution in a chart with given solvents. They also calculate the molarity of solutions in other problems.

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

For this moles, molecules and molecular mass worksheet, students solve 18 problems where they find the number of moles in a gas, they calculate the number of molecules in a sample of gas or they find the volume of gas in a...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson plan starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

In this formulas and equations worksheet, chemistry apprentices write the chemical formulas given the names. They calculate percent composition, balance equations, and calculate the mass of a substance present in a fertilizer. This is a...

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

Need a fun solution to teaching ... solutions? A series of puzzles provides reinforcement to key molarity terms and calculations. Science scholars determine the concentration of several solutions before using the information to solve...

In chemistry, the mole is a unit of measurement, much like a millimeter or liter. After learning about moles, scholars learn various equations relating to mass, volume, and concentration. They review each of these equations in a few...

In this moles worksheet students complete a set of calculations to find how many atoms and moles are in different substances. 

For this gas law worksheet, students review the Idea Gas Law equation and practice applying the equation to chemical reactions. Students write the balanced reaction, determine the limiting reagent, moles produced, and volume of gas...
