The University of the State of New York has designed a series of exams for 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,...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

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 instructional...

Students investigate the importance of significant figures through measuring and estimating. In this estimation and significant figures lesson plan, students measure pieces of paper and round their figures to the nearest marking on the...

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...

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 this honor chemistry I worksheet, students use all available resources to answer each question given. Students apply their knowledge of light, quantum theory of light, Bohr's model, photoelectric theory.

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

In this significant digits worksheet, high schoolers review the rules for performing calculations with significant digits. Students then express answers with the correct number of significant digits. This worksheet has 3 short answers...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Students compare and contrast the English and Metric system. In this chemistry lesson, students demonstrate how to convert English to metric and vise versa. They solve problems following the rules of significant figures.

In this chemistry worksheet, students examine the common characteristics of an acceptable graph that is meant to be used to display data.

Combine mathematics and science to calculate measurements of unmeasurable materials. Individuals use knowledge of density and volume to determine the thickness of the film used in production. They also apply stoichiometry to...

Litmus paper, why so blue? A chemistry lesson plan includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

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,...

In this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson plan keeps Avogadro relevant to your class all year long. 

Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

Students perform computer simulations on air dispersion. In this chemistry lesson, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a activity in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Avoiding lab safety rules will not give you super powers. The lesson opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and trying to...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Scientists have been studying exothermic reactions before they were cool. The lesson plan begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed...
