These 37 slides start with definitions of six types of functional groups, their molecular structure, and multiple examples or each. During the rest of the presentation, organic chemistry learners are given an opportunity to practice...

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the lesson requires...

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...

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...

Keep it simple with this chemistry assignment. Learners examine an acid-base titration graph and answer four questions about the data. Then they will balance neutralization equations and calculate molarity for several specific solutions....

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...

For this chemistry olympiad laboratory worksheet, learners design and carry out two experiments. They design one experiment to test for the percent mass of a substance in a solution and they design another experiment to identify two...

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...

Acquaint your chemistry class with acids and bases by showing this bold and bright PowerPoint. Viewers learn about the characteristics of acids and bases and stop at intervals to answer several questions about what they are learning. Use...

Now that your science class has experimented with pH indicator and identified acids and bases, they attempt to get the cabbage juice indicator back to its original color. This is done through neutralization of the acids and bases that...

Have your class write secret messages using Goldenrod paper and a basic liquid such as ammonia. This is a great way to illustrate the chemical reactions between acids and bases. This could lead to an exploration of chemical reactions and...

Create disappearing ink and send your own secret messages. Have your learners explore the properties of acids and bases in order to figure out how to cause a chemical reaction. After they understand the process, they can perform some...

Steve Spangler shows how to make your own litmus paper. Using blackberries, construction paper, and water, learners can make their own litmus paper in the classroom. Then, they can take different liquids, such as oil and soapy water, and...
