This site contains a brief introduction to the concepts of injection and detection in gas chromatography, focusing on the split/splitless injection port and flame ionization detectors. The treatment is similar to that in analytical chemistry textbooks, and includes detailed illustrations.

The Materials Science and Technology Teacher's Workshop (MAST) provides this experiment on forming low temperature glass. The module will allow students the chance to form low temperature glass and test for electrical conductivity. The lesson includes a step by step explanation of the laboratory...

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity to look at the ways in which energy is released in chemical reactions. The class will examine plaster of paris, bromthymol blue and the hydration of baking soda. Students will observe the temperature changes of...

This demonstration, presented by the National Nanotechnology Infrastructure Network, exposes students to the functionality of catalysts on a nanoscale. This lesson is "a great way to introduce or review reactants, catalysts, and adsorption, desorption, and diffusion. Use this demonstration after the...

This inquiry lesson teaches students about the properties of materials, specifically they will learn about superhydrophobic coated materials in contrast to uncoated materials. This contains a teacher's preparatory guide with lesson diagrams, pictures, material lists, and detailed procedures....

This primer on High Performance Liquid Chromatography (HCLC) gives a brief history and definition of liquid chromatography (LC), LC techniques, and defines both HPLC and UltraPerformance Liquid Chromatography (UPLC Technology). The other chapters of the primer are available on the left side of the...

Published by the National Nanotechnology Infrastructure Network, and created by Alonda Droege and the University of Washington, this 50-minute activity "explores how nanotechnology can be used to change the properties of a surface so that it either attracts or repels water." The Teachers' Guide PDF...

This lesson, developed Mark Steward, uses the Powder River Basin in Wyoming as context for a lab experiment. Students will have opportunities to demonstrate skills in measuring volumes and calculating percent composition based on recovery rates from the soluble metal solutions they work with, with...

This short YouTube video, which runs for 2:25, was created to show the viewer how to make "hot ice." First, they produce the solution by supersaturating sodium acetate and water by heating it over then stove, then chilling the solution, and finally create "hot ice" by touching the solution to make...

This website contains an ion chromatography simulator that can be run online or downloaded. The simulator focuses on separations of proteins using ion chromatography. Also included is linked reference information, an example of a homework assignment using the simulator, and some information on...
