General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific teacher notes give tips for mentoring minors through the lessons. Suggestions are made for options, community connections, and more. This is a comprehensive resource complete with lab sheets.
Students investigate moles and measure out a mole by mass and volume. In this mole lesson plan, students observe demonstrations of quantities of substances that measure 1 mole. Students use a solid aluminum block and ruler to measure the volume of the block and they determine if counting, weighing or using volume is easiest to find a mole.
Sal introduces chemistry students to the concept of "moles." He points out that a mole is number that helps a student to translate between grams and atomic mass units of any substance. Sal uses the element Aluminum to illustrate this point. The mass number for Aluminum is 26.98, so one mole of Aluminum is equal to 26.98 grams. As with many of his previous videos, Sal uses the Periodic Table to help explain these concepts.
The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles, including multiple-choice, short answer, problem solving, interpretation of charts and graphs. The content covers every topic within the typical general chemistry curriculum.
Teach your chemistry charges how to calculate amounts of metals produced during an electroplating process. This invaluable handout details the electroplating process and then provides three examples that you can work through with your class. Use it when you introduce the concepts of electroplating for the first time.
This is a review of how advanced chemistry learners handle thermodynamics equations and calculations. Charts and graphs are included for them to read in addition to solving related problems. You will find this resource useful as a review homework or preparation for a unit quiz.
A comprehensive selection of questions regarding the basic principles of chemistry. Thirteen questions ask your pupils to perform calculations about density and mass, give the atomic structure of certain elements, provide formulas, and balance equations. Complete this sheet as a class and then use it as a reference throughout a chemistry unit.
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 general chemistry curriculum with a focus on laboratory experience. You can use this as a final exam for your chemistry class. An answer key is attached.
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 answer questions about everything from properties of liquids and phase changes, to electrolysis products and molecular geometry. You could actually use this as a final exam for your class, a course review, or a practice for the actual chemistry challenge.
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 chemistry curriculum. Topics include, but are not limited to pH, molecular geometry, bonding, behavior of gases and solutions, phase changes, and chemical reactions. Use this as a final exam or as a practice for those who want to enter the nation-wide challenge.
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 chemistry class. This particular part of the three-part exam consists of 60 multiple choice questions. Read through it before assigning to make sure every question is relevant to your curriculum. As a bonus, you will find an answer key attached.
In this National Olympiad exam worksheet, chemistry apprentices answer sixty multiple choice questions including general chemistry topics such as atomic structure, gases, problem solving, writing and balancing equations and solutions. This and other National Olympiad exams are outstanding in content and format.
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 practice for the competition or to prepare for a final exam on behavior of gases, properties of metals, chemical reacitons, pH and titration curves, ionizaton energy, molecular geometry, and more!
Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and decomposition rate of hydrogen peroxide. The second requires that they determine the equilibrium constant for a reaction involving urea. All of these National Chemistry Olympiad exams are tremendous resources to use in your classroom as lab investigations or practical exams.
