# Gravity Battery

## Students will develop and use models on the macroscopic scale to illustrate that energy can be accounted for as a combination of energies associated with the motion and relative position of objects.

## Summary

**ESS.3.5 **Develop and use **models** on the macroscopic scale to illustrate that energy can be accounted for as a combination of energies associated with the notion of objects and energy associated with the creative positions of objects. Emphasize relationships between components of the model to show that energy is conserved. Examples could include mechanical systems where kinetic energy is transformed to potential energy or vice versa. (PS3.A)

## Lesson Performance Expectations

- Students will complete a model of the carbon cycle including quantitative data.
- Students will look at the balance of carbon among the systems and construct an explanation of how the movement of carbon can result in changes to the system.
