Exploration of Physical Science: Simulation Library Vol. II is a vast collection of 100 computer simulations encompassing a full-range of physical science topics. Developed by Dr. Carroll and Dr. Amiri of Weber State University, the software program utilizes a conceptual approach to teach physical science principles. The simulations are categorized into three learning levels: 1) introductory, 2) intermediate, and 3) advanced; addressing the needs of introductory physical science, high school physics, and college physics courses. The multi-level learning feature gives the software package a great deal of flexibility to meet a wide range of student needs. The Simulation Library Vol. II collection significantly broadens the scope of the Volume I collection. Each simulation re-creates a real world physical event, with the student given full control over the relevant experimental variables. Experimental parameters are easily manipulated using an assortment of slider controls; physical behaviours are animated on-screen using graphics that employ rich colour and depth; and physical quantities are displayed using digital readouts, graphs, and histograms. Each simulation has a readily accessible help screen providing information on using the simulation.
The vast collection of simulations may be used in a variety of ways: (1) as an instructor lecture aid for demonstration purposes in front of the classroom, (2) for student use as a computer-based lab activity. Exploration of Physical Science simulations can be used to introduce a physical science concept, or serve nicely to reinforce and extend a lab (involving apparatus) that has already been performed. The ready-to-run simulations and highly intuitive interface allows first time users to immediately use the simulations and begin exploring with no preliminary time investment - essentially providing a ready to go lab experience.
