Energy is Energy: A two-part Workshop on a Consistent Approach in Bio, Chem, and Physics

Part 2: Chemical Changes and Biology

Part 2 will continue to explore key methods to help students understand how energy, a key cross-cutting concept in the Next Generation Science Standards, can be represented by the unified idea of energy storage and transfer in the physical and biological world. The simple but powerful representation tool, Conservation of Energy (COE) diagrams, will continue to show how one can qualitatively keep track of energy in various changes. This graphical, visual approach eliminates the conflicts among the ways energy is usually taught in bio, chem, and physics, thus helping students build a deep, applicable understanding of this important concept as they study the various disciplines from 6th through 12th grade.

Part 1, introduced COE diagrams to represent energy storage and transfer in various demonstrations and scenarios in physics, building the fundamental idea of how energy storage changes when objects/particles attracted to each other are separated. This idea was then connected to chemistry as a way to describe how energy is stored during observable phase changes based on particle behavior change.  Part 2  further builds upon this as it delves into understanding energy in chemical changes and then applying the same idea in biological systems.
