Physiological simulation software for the A & P laboratory, PowerPhys 3.0 allows users to explore physiology principles through 14 self-contained activities. Each activity contains objectives with illustrated and animated review material, pre-lab quizzes, pre-lab reports, data collection and analysis, and a full lab report with discussion and application questions. Experiments contain randomly generated data, allowing users to experiment multiple times but still arrive at the same conclusions. Authored by teaching lab faculty, these activities focus on core physiological concepts and reinforce techniques experienced in the laboratory.
