 Hot and Cold Experiment: Temperature and Resistance of Electronic Materials The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan which will help students understand how temperature affects the conductivity, or resistance, of a variety of electrical materials and devices. The basic scientific principles of heat, metals and semiconductors is outlined. The instructor will set up five beakers of water at a variety of temperatures. The... http://matse1.matse.illinois.edu/sc/b.html
 Digital Scale Teaching Element This lesson, from the Technological Education Pathways Partnership (TEPP), uses a bathroom scale to explore the load cell technology used in weigh stations on interstate highways. A Word document explains the concept of the Wheatstone bridge measure of electrical resistance, and two PowerPoint presentations lead students in dismantling a bathroom scale and balancing the bridge of the scale's load... http://fmcctepp.org/elements/scale.html
 Efficiency and Power The following animation shows how a load resistance results in increase in output power. Use the up and down arrow keys to change the load resistance. While viewing, note the following: power output peaks when load resistance equals generator resistance, further increases in load resistance results in lower output power. The objective is to describe the optimum load versus power settings for... http://matec.org/animations/matec/M106FL01.swf
 Electronics Simulations and Lessons These are five free downloadable simulations for experimenting with and learning basic electronics concepts. The software includes a LED (Light Emitting Diode) Simulation which demonstrates band gap theory. The Overview Complex AC Circuit program allows users to adjust the voltage, load resistance, capacitance, and inductance and see the resulting change in the current. The DC Circuit Parallel... http://www.scienceshareware.com/electronics.htm
 Analog Electronics: Basic Circuits of Operational Amplifiers This site offers a set of interactive operational amplifiers (OAs) simulators with detailed lessons and basic circuit schematics (including theory). The Java applets provided include an inverting amplifier, summing amplifier, difference amplifier, differentiator, and integrator circuit amplifier. http://www.chem.uoa.gr/Applets/AppletOpAmps/Appl_OpAmps2.htm...
