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...

General chemistry classes practice spectroscopy. They grasp the relationships between wavelength, absorbance, and solution concentration. Additionally, they gain valuable practice using laboratory equipment such as burets and pipettes....

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

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...

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...

I love classroom games, and this plan deftly describes how you can use the game Concentration across the curriculum to reinforce skills. I wish I would have thought of this when I was teaching this age level. These kinds of games are...

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

High schoolers design an experiment to test for the concentration of chloride in products. In this analysis of chloride concentration lesson plan, students develop and conduct an experiment to find the amount of chloride ion in a...

More than 83,000 scholars earned college credit, thus saving time and money by passing the AP Chemistry exam in 2017. Use the exact test questions covering concepts from activation energy to solubility to prepare for the upcoming...

Mix a great resource in to your engineering repertoire. An engaging video discusses diffusion and mass transfer. It explains how a difference in concentration is the driving force for this mechanism. 

The longest functioning straw is 10.3 meters tall. The dilemma—if this is true— is how can a tree be taller than 10.3 meters? A video researches the answer and presents it in a thought-provoking video lesson. There are many components to...

Watch as colored water droplets chase each other around a slide. The factor that affects the behavior is the concentration. Part of a large playlist, an experimental video provides an explanation for the behavior of the water droplets in...

Scientists require specific chemical solutions for their experiments. In the seventh and final installment in a series that integrates chemistry and algebra II, scholars learn to set up a system of equations to solve the volume of a...

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

You'll need to concentrate on the concentration lab to get it done. Given a virtual beaker with a silver chloride solution of unknown concentration, scholars find the silver ion concentration in the solution. Of course, they must show...
