About This Issue John W. Moore and Jon L. Holmes "n vers ly 01 W smnsin-Maatson Madson. W 53706-1396 How to Use These Programs Using SIRS, one may explore the behavior of chemical systems and conduct simulated experiments of one's own (or better still, the students') devising. One may ask, 'What do you think happens next?" or "What would hapDen if ...?". exdore ~ossihilitieswith the class. and then Hsk the ~o&~;ter toshow what the chemicals actually do. e inThe content and level of these SIRSare a -m- r o-~ r i a t for troductory courses a t high school or college. SIRS are not intended to redace laboratories or classroom demonstrations; insteadAtheycan enhance and extend live ex~erimentsand demonstrations. For example, one might uHe SIR TOR to explore pressure in mercury iol: umns and thus show how manometers work, do a live demonstration of Boyle's law, and then discover Charles' and Avogadro's laws using the simulated experiments and graphing facilities in SIR Ideal. Anyone who teaches the

topics listed for the 12 SIRS in this issue will find that these programs enhance classroom presentations. HardwareISoftwareRequired
Programs in Series B of JCE: Software are designed for IBM PSI2, PC, or PC-compatible microcomputers with 640K of RAM and one disk drive. SIRSwill occupy nearly 900 K of hard-disk mace or can be run from a sinele 1.2 MB or 1.44 MB floppy disk drive. VGA or com~atihle graphics (CGAand EGAgraphics will not work) and monitor and a Microsoft compatible mouse are required. PC- or MS-DOS 3.1 or later is also reauired. Effective use of SIRS requires a classroom projectiondevice such as an overhead projector panel or a three-gun projector.
