Description

Students solidify their understanding of the law of conservation of energy, review all major concepts from the week (forms of energy, kinetic vs. potential, energy transfer methods, conductors/insulators, circuits), and complete a comprehensive unit assessment.

Learning Objectives

  • Apply the law of conservation of energy to explain energy transformations in real-world systems

  • Synthesize knowledge of energy forms, transfer methods, and materials to solve problems

  • Demonstrate comprehensive understanding of the Energy unit through a review assessment

## The Big Idea: Conservation of Energy

This week, we have explored many forms of energy, how energy transfers and transforms, and how materials affect energy flow. Today, we bring it all together with the most important principle in the entire unit: the law of conservation of energy.

This law states that energy cannot be created or destroyed. It can only change form or transfer from one object to another. The total energy in a closed system always remains constant. When we say something 'uses' energy, what we really mean is that it transforms energy from a useful form into less useful forms (usually thermal energy dispersed into the environment).

💡 Week in Review

Monday: Energy is the ability to do work; kinetic vs. potential; six major forms. Tuesday: Deep dive into thermal, light, sound, electrical, chemical, and mechanical energy. Wednesday: Heat transfers by conduction (contact), convection (fluid), and radiation (waves); expansion and contraction. Thursday: Conductors allow energy flow; insulators resist it; circuits need a complete loop. Friday (today): Conservation of energy ties everything together.
