Teacher Resources for Instructional Planning


HS, Chemistry Std 6.5: Determine empirical or molecular formulas for a compound using percent composition data.

Lesson Plans: Mass Relationships in Chemical Reactions Students prepare and determine the percentage yield of sodium chloride, and gain an understanding of mass relationships in chemical reactions. Empirical Formulas Find the molecular formula, given the molecular mass and the empirical formula. Molecular Modeling Students will learn how to generate three-dimensional images of some simple inorganic and organic molecules they encounter in their introductory chemistry class. Percent Composition of Gum Students will understand the concept of percent composition of compounds and be able to perform the associated calculations.

Resources: THE SAME EVERYWHERE Chem-4-kids periodic table. Tom Stretton's Chemistry Pages Great tutorials and practice problems The Periodic Table of Comic Books Associates each element with a comic reference - fun Interactive Periodic Table Created by an eighth-grade student! Chemicool Periodic Table This is an all-purpose, interactive periodic table that would be useful for high-school chemistry classes. In addition to general information about the elements, it includes the following: states, energies, oxidation and electrons, appearance and characteristics, reactions, conductivity, abundances, and more. Pyrotechnics: It's Elemental Some of the important elements that make a firework work. Chem4kids Great tutorials and activities.
