It is par of the UVA Virtual Lab collection. http://www.compadre.org/introphys/items/detail.cfm?ID=10558 http://virlab.virginia.edu/VL/VDG.htm http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=10558 Thu, 23 Dec 2010 00:00:00 EST A short article describing a Van de Graff demonstration using a bat made from fake fur. The bat hovers over the Van de Graaff generator and under the right condition it can fly and land over the lap of a student. http://www.compadre.org/introphys/items/detail.cfm?ID=10549 http://dx.doi.org/10.1119/1.2342570 http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=10549 Thu, 23 Dec 2010 00:00:00 EST This is an interactive simulation on the topic of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI). The user can change the applied magnetic field and the RF signal and observe the effect on spins. In the NMR mode, the user can choose between various from among several atoms. In the MRI mode, the user can elect to add a tumor to the head being visualized. http://www.compadre.org/introphys/items/detail.cfm?ID=6111 http://phet.colorado.edu/en/simulation/mri http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=6111 Fri, 12 Mar 2010 00:00:00 EST This page provides a description of the process that a hiker had to go through in trying to start a fire by making a lens out of ice. The author also provides a link to other successful and less successful attempts. http://www.compadre.org/introphys/items/detail.cfm?ID=8692 http://www.wildwoodsurvival.com/survival/fire/ice/rb/rbfirefromice1.html http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=8692 Sat, 14 Mar 2009 00:00:00 EST This is a hands-on classroom activity on electricity and magnetism created by the Advanced Light Source team as part of a 1996 workshop for teachers. http://www.compadre.org/introphys/items/detail.cfm?ID=8069 http://www.lbl.gov/MicroWorlds/teachers/movingelectrons.pdf http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=8069 Wed, 01 Oct 2008 00:00:00 EST This Adobe Shockwave simulation, provides the gravitational analog for two "electrical resistors" placed in parallel. http://www.compadre.org/introphys/items/detail.cfm?ID=7968 http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=7968 Sun, 07 Sep 2008 00:00:00 EST This resource provides instructions for constructing a simple "Soda Bottle Speaker." A parts list and information about the materials user are included, as well as two experiments to study the properties of the speaker. http://www.compadre.org/introphys/items/detail.cfm?ID=3178 http://physics.mercer.edu/marone/soda/sbsintro.htm http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=3178 Tue, 02 Sep 2008 00:00:00 EST This webpage contains an interactive simulation that allows users to explore the physics behind lasers. Two simulations are available, the first showing the optical excitation of a single atom and the second showing the result of interactions between multiple atoms. http://www.compadre.org/introphys/items/detail.cfm?ID=4425 http://phet.colorado.edu/en/simulation/lasers http://www.compadre.org/introphys/bulletinboard/Thread.cfm?ID=4425 Tue, 29 Jul 2008 00:00:00 EST
