[初賽第一階段] 保護（2） [Preliminary Phase 1] Conservation (2)

Big Concept: Conservation Topic: Dimensional Analysis and Fermi Estimation in Physical Systems Bloom's Taxonomy: Understand, Apply, Analyze Learning Goal: Students will be able to: understand that energy is conserved in a closed system; understand that energy can be transformed between different forms (e.g., kinetic, potential, thermal); understand that apparent energy loss often reflects transformation rather than disappearance; distinguish between mechanical energy and total energy in a system; interpret observed changes in motion as evidence of energy transformation; use observations and data to infer whether energy is conserved; evaluate whether conclusions about energy conservation are supported by empirical evidence, and analyze patterns in physical systems to explain how energy changes form over time Key Learning Points: Energy conservation can be inferred from consistent patterns in observed motion and system behavior. Objects speeding up or slowing down reflect transformations between different energy forms. Even when motion stops, energy is not lost but transferred to other forms such as heat. Repeated observations allow identification of patterns that support conservation. Understanding relies on connecting observable changes to underlying energy transformations, even when not directly visible. Note: This design emphasizes learning through observation and pattern recognition. Students begin with observable changes in motion and use these patterns to infer energy conservation and transformation.
