443412.141 Electron Microprobe Analysis (MIT)
http://www.merlot.org/merlot/viewMaterial.htm?id=884505
The electron microprobe provides a complete micrometer-scale quantitative chemical analysis of inorganic solids. The method is nondestructive and utilizes characteristic X-rays excited by an electron beam incident on a flat surface of the sample. This course provides an introduction to the theory of X-ray microanalysis through wavelength and energy dispersive spectrometry (WDS and EDS), ZAF matrix correction procedures and scanning electron imaging with back-scattered electron (BSE), secondary electron (SE), X-ray using WDS or EDS (elemental mapping), and cathodoluminescence (CL). Lab sessions involve hands-on use of the JEOL JXA-8200 Superprobe.10.626 Electrochemical Energy Systems (MIT)
http://www.merlot.org/merlot/viewMaterial.htm?id=883965
10.626 introduces principles and mathematical models of electrochemical energy conversion and storage. Students study equivalent circuits, thermodynamics, reaction kinetics, transport phenomena, electrostatics, porous media, and phase transformations. In addition, this course includes applications to batteries, fuel cells, supercapacitors, and electrokinetics.5.72 Statistical Mechanics (MIT)
http://www.merlot.org/merlot/viewMaterial.htm?id=884061
This course discusses the principles and methods of statistical mechanics. Topics covered include classical and quantum statistics, grand ensembles, fluctuations, molecular distribution functions, other concepts in equilibrium statistical mechanics, and topics in thermodynamics and statistical mechanics of irreversible processes.6.701 Introduction to Nanoelectronics (MIT)
http://www.merlot.org/merlot/viewMaterial.htm?id=884231
Traditionally, progress in electronics has been driven by miniaturization. But as electronic devices approach the molecular scale, classical models for device behavior must be abandoned. To prepare for the next generation of electronic devices, this class teaches the theory of current, voltage and resistance from atoms up. To describe electrons at the nanoscale, we will begin with an introduction to the principles of quantum mechanics, including quantization, the wave-particle duality, wavefunctions and Schrödinger's equation. Then we will consider the electronic properties of molecules, carbon nanotubes and crystals, including energy band formation and the origin of metals, insulators and semiconductors. Electron conduction will be taught beginning with ballistic transport and concluding with a derivation of Ohm's law. We will then compare ballistic to bulk MOSFETs. The class will conclude with a discussion of possible fundamental limits to computation.Attention grabbers

I found this on the web while I was brain storming unique ways to get the attention of my students. I sometime find it hard to do something exceptional that I maintain their attention for the whole period. So I went searching for help and found this. Very creative and innovative. Something as simple as timing activities to giving student a checklist of the high points of the lesson then asking if it was covered in your presentation are some of the ideas I thought were neat.Joseph Priestley on Phlogiston
http://www.merlot.org/merlot/viewMaterial.htm?id=759089
Primary resource wherein Joseph Priestley defends the theory of Phlogiston, and attempts to falsify theories of combustion, oxygen, and elements, or "the new system of chemistry״. This letter was written in 1796.Buoyancy and high altitude ballooning: the Red Bull Stratos mission
http://www.merlot.org/merlot/viewMaterial.htm?id=735047
A detailed analysis of buoyancy in the context of Felix Baumgartner's historic jump from 39 km altitude as the culminating event of the Red Bull Stratos mission. Buoyancy was provided by a helium-filled balloon that made the equipment less dense overall from the surrounding air.This article takes readers through the calculation of the density of the relevant gases (air and helium) and the net density of the ascent equipment. An error analysis shows that helium and air must have counter-diffused through the balloon wall and estimates the composition in the balloon. Also discussed are possible reasons for why the ascent equipment achieved a greater altitude than expected.Osmosis Desalination and Carnot

Discussion of Osmosis and Desalination following Carnot ideas. The energy required for desalination. Sourcebook for Teaching Science
http://www.merlot.org/merlot/viewMaterial.htm?id=707704
The Sourcebook for Teaching Science – Strategies, Activities, and Instructional Resources, provides new and experienced teachers a wealth of teaching strategies, resources, lessons, activities, and ideas to enhance the teaching and learning of physics, chemistry, biology, and the earth and space sciences. Resources are based on learning theory, and are designed to stimulate student interest and involvement. As students engage in the activities of this book, they develop higher order reasoning skills, and a deeper understanding of scientific concepts and their relevance to their everyday life. The Sourcebook for Teaching Science is designed to complement any secondary school science curriculum. Science teachers will find ready-to-use demonstrations, experiments, illustrations, games, puzzles, analogies, lessons, activities, and strategies, as well as explanations of how to adapt these for English learners and diverse student populations. All topics are accompanied by extensive background material, providing teachers with the scientific, organizational, and pedagogical principles necessary for successful classroom implementation.Periodic Table Interactive
