Young scholars record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Thirty multiple-choice questions and their answers are provided in this resource. It was written for a general chemistry course and queries test takers on scientific notation, mixtures, chemical symbols, electric charges, Dalton's atomic...

In this percent composition worksheet, young scholars find the percentages of atoms in compounds and they determine empirical formulas given the percent of each atom in a compound.

Plenty of time was invested in creating this detailed presentation. The first slide alone includes several steps that support your explanation of percent composition, a precursor to understanding how to write empirical and molecular...

Learners differentiate between point and non-point pollution and determine how the different types of pollution are harmful to aquatic ecosystems. They complete a series of tests on a sample of "polluted" water and a sample of "pure" water.

Arkansas ranks first in the entire world in the production of bromine! Here is a lesson which guides middle schoolers through a study about the formation and history of Arkansas' bromine reserves. They also looks at the many uses of...
