ChemCollective: Concept Tests Our concept tests use qualitative multiple choice questions to assess the understanding of key chemical concepts. (Please email us for answers and suggested classroom uses). Thermochemistry Energy and Enthalpy Thermodynamics Concept Test Concept tests that can be used as part of in-class activities to help students reason about energy and work. Equilibrium LeChatlier's Principle Chemical Equilibria Concept Test These equilibrium based concept tests can be used as part of in-class activities to help students reason about equilibrium concepts. Progress of Reaction Chemical Equilibria Concept Test These equilibrium based concept tests can be used as part of in-class activities to help students reason about equilibrium concepts. Equilibrium Calculations Chemical Equilibria Concept Test These equilibrium based concept tests can be used as part of in-class activities to help students reason about equilibrium concepts.
Chemistry Interactive Video Animations Chemistry Based Animations These animations support the teaching of concepts in chemistry in freshman through graduate level courses. Some of the QuickTime movie are without audio, and some of the audio--from a few of the sound augmented QuickTime movie--has been stripped and made available in Real Audio's streaming audio format. Conceptual Chemistry Questions The new AP Chemistry Curriculum and the NGSS both focus on developing deep conceptual understanding. In order to achieve this, teachers must identify the objectives they need to teach to and stockpile a good assortment of conceptual questions for formative and summative assessments to support those objectives. An understanding of common misconceptions related to chemistry content is also important in designing meaningful assessments.
How Does an Orange Peel Pop a Balloon? Chemistry, of Course! By Tom Kuntzleman, Tori Talaski and Charles Schaerer There is a new experiment circulating the web. Check it out: Isn’t that cool? The juice from an orange peel causes a balloon to pop. Conceptual Questions & Challenge Problems in Chemistry A. "Conceptual Questions and Challenge Problems in Chemistry" (web site) is part of the Journal of Chemical Education Question Bank, providing "a library of free response and multiple choice conceptual questions and challenge problems, tips for writing these questions and problems, and a discussion of types of concept questions." "This site is intended to be a means of sharing conceptual questions and challenge problems among chemical educators." 1.

States of Matter - PhET Interactive Simulations Topics Atoms Molecules States of Matter Description Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases. Sample Learning Goals Balmer Series The Bohr Model Niels Bohr proposed a model for the hydrogen atom in 1913 that described discrete energy states are associated with a fixed electron orbit around the nucleus. Importantly, an atom cannot discharge energy while its electrons are in stationary states. An electron can only emit energy by changing energy states. To change energy states, an electron must move from one orbit to another by either absorbing or emitting energy.
