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...

Practice rounding numbers to a certain decimal by solving in-class problems. Learners will solve several multiplication, division, addition, and subtraction problems while rounding to a specific decimal. They will also check their work...

In this significant figures worksheet, students solve 30 problems. They round numbers to three significant figures, they indicate the number of significant figures and they do calculations to the correct number of significant figures.

Middle and high schoolers study significant people who shaped the 20th-century history and are introduced to database tools. Researchers use the Internet to research five 20th century history makers. They write a short biography of five...

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...

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,...

In this significant figure worksheet, young scholars read six diagrams of a graduated cylinder to the proper number of significant figures. They then go to twelve lab stations and record the proper measurement to the appropriate number...

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...

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...

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...

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...

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.
