Unit Description Unit 4 Energy
This unit focuses on energy transformation and conservation. Conversions among thermal,
chemical, magnetic, electrical, and mechanical energy types are examined. In addition, mechanical advantage and efficiency of simple machines are investigated.
Essential Questions Can students:
1. discuss the relationship among work, power, and energy and solve problems demonstrating
these relationships?
2. explain and solve problems demonstrating energy being transformed from potential to
kinetic energy?
3. list ways individuals consume energy?
4. calculate mechanical advantage and efficiency of simple machines?
5. explain why energy is so expensive even though energy comes ultimately from the sun?
6. apply energy and work transformations to real-life situations?
7. discuss why we have energy shortages?
