Stoichiometry Files

• Granny deMole (2003)  A zip file contaning 34 PDF, RTF and PowerPoint files, describing the activities of a 30 day unit on Chemical Reactions, Stoichiometry, & Solutions by the authors Donna Ahlswede, Laura Herbig, and Rosemarie Placek.
• Stoichiometry By The Recipe  A word document, author John S. Brodemus, describing a method by which students learn to do whole equation stoichiometry when given just one component's amount. It does NOT use mole ratios. When used as the paradigm for doing stoichiometry problems, even students in lower ability classes are able to solve limiting reactant problems.
• Chemical Problem Solving: Mathematical  A Word document, author Andy Cherkas, describing a method to help students with problems solving stoichiometry problems
• From a Cup Cake Recipe to Stoichiometry  A Word document, author Shahrokh Ghaffari, describing how to use a recipe as an anology for stoichiometry.
• Balancing Equations (2003)  A zip file containg a powerpoint presentation and student assignment by Jenny Dunn
• Ice Cream Colligative Properties  Five Word documents in a ZIP file, author Bettyann Howson, the five files describe the ice cream lab with and without calculations the other documents help students gain familiarity with the concpts required to understand the colligative properities of matter.
• Reaction Flashcards for A.P. Chemistry  A word document, author Kathleen A. Kitzmann, describing flashcards, a method that students can use to organize subject matter, in this case chemical reactions.
• Water Softening a Chem Com Activity  Four Word documents in a ZIP file, author Bettyann Howson, the four files describe the basic assignment plus skills assignments appropriate to the concepts required.
• HOLY MOL-EE (2003)  A zip file of 8 PDF and Word files, author Lynda Jones, describing activities, including songs, for teaching the mole concept
• Photochemistry - Oxidation of Luminol (2003)  Four Word documents in a zip file, author Klunder-Kosmas-Moskaluk, describing the oxidation of luminol with bleach with a student activity to calculate the reacting mole ratio between bleach and luminol
• Hey! What's This Tomato Doing in My Chem Lab?  A word document, author Patricia Mason describing a three-part, weeklong laboratory experience to introduce percentage composition of compounds. This experience meets the national science education standards by using a constructivist approach, involving group work, developing hypotheses, interpreting data, and reporting of results.
• The Copper Cycle  A word document, author John Severson describing The Copper Cycle, an exceptional lab activity that promotes student understanding of reaction types, stoichiometry, and writing and balancing of equations.
