the smallest size drive, rated at230 volts and 1 hp. The current price for these drives is $235,which meant we could buy drives for all eight workstations forless than the price of a single “name brand” drive. The drives arepulse-width-modulated, IGBT drives and are fully-featuredincluding simple volts/hz control, sensorless vector control withautotune, and adjustable acceleration/deceleration ramps withlinear and S-curves, among others. The drive has an RS485 portfor communications that can be configured for ethernetcommunication with an optional interface. The drive is relativelycompact, measuring less than 5" wide, 7" tall, and 6.5" deep.The drive can be configured using the human interface module(HIM), which is mounted at the top, right

F i g 1 : T r a c t o r U s e dThe second major resource made available was the easy availability of hydrogen gas resultingfrom the presence of the electrolyzer itself. The unit was a Hydrogenics model HySTAT-30refueling station6 which consists of a generation and compression module, storage ability and adispenser module. This system is capable of producing about 30 kg of hydrogen per day and isable to dispense the gas at controllable pressures up to 5000 psi. The water supplied to this unitwas

technical and social content.This need for energy education is the fundamental motivation for the energy awareness efforts atBaylor University. According to the National Energy Policy7, the U. S. must have between 1,300and 1,900 new electricity generation plants in place to meet the projected 45% increase inelectrical demand by the year 2020. Economic and political policies often reflect the unspokenassumption that the United States will be able to continually increase its reliance on naturalresources and more importantly, energy resources. On May 2, 2007, a local newspaper editor Page 13.491.2took time to remind the public of the energy history

propel a vehicle is given by the following equation (see, for instance, reference 1): W% req ? ]RL - Ma _Vwhere W% req is the power required at the wheels to accelerate the vehicle and overcome drag,rolling resistance, and climbing forces. The instantaneous vehicle speed is V. The “road load” is Page 13.50.3 1 RL ? tV 2C D A - fW - W sin s 2where the first, second, and third terms on the right hand side are the aerodynamic drag, rollingresistance, and climbing forces. The quantity f is termed the rolling resistance

produce the same output voltage from a mass flowcontroller. The GCF is a function of specific heat, density, and the molecular structure of thegases. In our case pure hydrogen is used as the baseline gas but flow controllers are usuallycalibrated with nitrogen. To calculate the Gas Correction Factor (GCF) for pure gases, followingformula is used: (0.3106)( S ) GCFx = (d x )(cp x )where GCFx is the gas correction factor for gas x (In our case hydrogen gas used),0.3106 is the factor of (Standard Density of nitrogen) and (Specific Heat of nitrogen),S is the molecular structure correction factor where S is 1.03 for
range of scientific applications. ‚ Epistemological development that provides the cognitive infrastructure for longer-term gains in scientific reasoning and correlates with more general advances in critical thinking. ‚ Critical thinking as demonstrated by increasingly sophisticated analysis, evaluation, application and synthesis as indicated, in part, by the ability to discover patterns of information in data across fields, interpret the meaning(s) of those patterns, and argue convincingly for significance of the interpretation. ‚ Greater engagement of students in learning.ResultsA comprehensive set of both quantitative and qualitative development measures have beenassessed throughout the ES
