At our high school, students in Chemistry or Culinary classes take part in an extensive Molecular Gastronomy (MG) project. Drawing inspiration from chefs Alton Brown ("Good Eats") and Marcel ("Marcel's Quantum Kitchen"), as well as newly developing creative menus at restaurants, students work in groups of two or three to select a dish to re-innovate. MG basically transforms "ordinary" food into so...

Empirical and molecular formulas definitely comprise a conceptually difficult topic for high school students to understand. Here is a strategy that may make at least the mathematical process more accessible. On a graphing calculator, make use of the "Lists" function. In L1 input the grams of each element present (e.g. for water, entering 11% hydrogen and 89% oxygen would be 11 g and 89 g). In L...

I will look into these suggested sites! I am a fan of most resources on . My AP students found chemmybear shapes to be helpful for illustrating the 3-D shapes of molecules. You can find animations, hints, and tutorials for various topics at this site. I think it's worth it to poke around a bit!

4 Helpful Chem Resource for Intro and Reinforcement
This SciGuide provides a multitude of links relating to atoms, matter, and chemical reactions. It is organized into three major themes: 1) Interactions of Matter, 2) Descriptions of Matter, and 3) Classifications of Matter. Material is offered for topics such as rates of reactions, types of reactions, types of bonds, acids and bases, mixtures vs. pure substances, and the periodic table. It may require a bit of time for you (the instructor) to follow links and find ones that are especially applicable to your classroom, but there are useful applets and tutorials available. I like the web-based balancing chemical equations activities -- tons of practice problems are given and can be scored online immediately. I also like the Virtual Lab -- you can mix different reagents and monitor temperature change, molarity, and pH. This SciPack would best be utilized as a means of introduction to chemistry/physical science topics because general definitions and descriptions are given. The tutorials could then be used for students to review and reinforce what they have learned. For most of the topics, student samples and/or many examples of practice problems are provided.
