Chemistry WebQuest: Percent Composition Perfection
Welcome to Percent Perfection! Today’s WebQuest will help you investigate how to calculate percent composition of chemical substances — both from the chemical formula and from experimental data. You’ll start by watching a introductory video, explore informational content, play with interactive tools, and finish with a review quiz to test your understanding. By the end, you’ll confidently find out what percent of a compound is made up by each element and how to calculate that from real data!

Le Chatelier's Virtual Lab Activity
In this virtual lab activity, students use the online PHET simulation called "reactions and rates" to investigate how equilibrium changes based on stress to equilibrium. Stress includes adding or removing product or reactant and increasing and decreasing the temperature. Students SHOULD already be familiar with potential energy diagrams and endothermic and exothermic reactions. This corresponds to 3.4j and 3.4v major understanding and skill on the New York State chemistry core curriculum. Studen
