4434Chemical Excelets: Interactive Excel Spreadsheets for General Chemistry
http://www.merlot.org/merlot/viewMaterial.htm?id=86263
This is a collection of over fifty interactive Excel Spreadsheets (aka - simulations) or Excelets for discovery learning in general chemistry. The Excelets range from simple calculation aids to exploring concepts by bringing the mathematics alive. Topics covered include the bond energy calculator, temperature scales, ideal gas law, interactive periodic trends, Beer’s Law, kinetics including competing/consecutive reactions and radioactive decay, weak acid behavior, buffers, weak acid distribution diagrams, and potential energy diagrams plus the influence of random and/or systematic error in many of the topics. Guided-inquiry activities are included with many of the spreadsheets. A link to a "How to" guide for developing Excelets is provided.MatSci Excelets: Interactive Excel Spreadsheets for Materials Science
http://www.merlot.org/merlot/viewMaterial.htm?id=348518
This is a collection of over two dozen interactive Excel Spreadsheets (aka - simulations) or Excelets for discovery learning in introductory materials science or to add a materials science component to other courses. The Excelets range from manipulating a multivariable equation, animating a concept, or managing a small database to explore concepts by bringing the mathematics alive to enhance the dynamic nature of concepts. Excelets promote an engaging pedagogy via predict, test, and analyze in the classroom. Topics covered include the crystal structure of metals, the vibrations in solids, bonding, band gaps, x-rays in crystalline solids, exploring the periodic table to compare metals and non-metals, thermal expansion, and carbon nanotubes. Guided-inquiry activities are included with some of the spreadsheets. A link to a "How to" guide for developing Excelets is provided. This work is supported by the Howard/Hopkins/PGCC Partnership for Research and Education in Materials (PREM), which is funded by NSF Grant No. DMR-0611595.
