Here is a summary of the SI/Metric System, how it works, and many examples of how to do conversions (showing both the factor label method and a proportionality method) as well as some nice examples of estimates using the system to help students gain "fluency" in the SI system. Lots of practice examples are also included.

This lab lets students make use of self-inflating balloons to investigate concepts of stoichiometry, gas laws and chemical reactions.

This PowerPoint presentation shows examples of numerous calculations that are widely used in general chemistry, including molar mass, percent composition, empirical and molecular formula as well as stoichiometric calculations, percent yield and limiting reagent problems. Examples of each type of problem are provided and solved clearly and logically.

This PowerPoint covers the basics of atomic structure, including atomic number, mass number, isotopes and average atomic mass. It also includes historical evidence from Rutherford's Gold Foil experiment and J.J. Thomson's cathode ray tube studies.

A PowerPoint presentation on net ionic equations, building on electrolytes (strong, weak, and non), spectator ions and solubility rules.

All students need to understand the basic concepts of ionic and molecular naming and formula writing. Plenty of examples and practice problems, all organized to help students understand things like metal/nonmetal/metalloid, monoatomic ions and the logic of the periodic table, multivalent elements and how to distinguish ionic and molecular compounds. Lots of practice examples as well.

Here is a good summary of a logical way to classify matter, along with examples of element/compound mixture practice, homogeneous vs. heterogeneous examples, phase changes and plenty of practice examples.

This packet covers: balancing basics types of reactions an reaction classification predicting reaction products using solubility charts to predict states of matter of products there are lots and lots of examples and practice problems.

Here is a nice summary of the main concepts of density, including calculations for D,m, and V, as well as conceptual examples of why objects float or sink. there is also some tie-in to sig figs in the calculations.

A thorough (but not overdone) summary of concepts such as: the mole conversions between grams.moles and particles molar mass percent composition empirical formula molecular formula Lots of examples and practice!!

This presentation describes the four quantum numbers and how they relate to each other as well as properties of light and waves as related to quantum theory.

Examples of each type of problem are provided and solved clearly and logically.

This presentation demonstrates how to apply concepts such as significant figures to calculations involving density and heat concepts in general chemistry. Examples of endothermic and exothermic processes and shown as are methods for determining the heat capacity of a metal.

This presentation describes a logical approach to electron configurations, stressing patterns and organization related to the periodic table, as well as periodic properties. Some exceptions (with logical reasons for them) to patterns are provided.

This presentation describes both qualitative and quantitative approaches to the major gas laws, providing examples of each major law as well and descriptions o f general relationships (inverse and direct). There is a brief descriptive approach to the Kinetic Molecular Theory as well as applications of the ideal gas law and ideal vs. real gases.

A nice packet with summaries and examples of alpha, beta an gamma decay, half-life examples and problems, the working of power plants and bombs, as well as transmutation equations and fusion.

This handout provides basic information of scientific exponential) notation, how to covert to and from it and plenty of practice examples.

This handout/worksheet/practice set explains the importance of significant figures, why they are used and includes examples and plenty of practice, including how to apply sig fig rules to different types of calculations

Systematic approach to balancing redox equations using the half reaction method. Examples for both acidic and basic solution are shown.
