 * Describe the relationships among the parts of a system, the ways that they work together, the flow of energy through the system, and the feedback and control mechanisms present in the system.
 * Trace the movement of water through all parts of the earth system, living and non-living, from the cellular scale to the global scale, and connect the behavior of water in each different part of the system to its physical properties.
 * Design, implement, record, explain, and justify safe and effective laboratory procedures to determine the relationship between two variables, controlling for other factors that might also affect the relationship.
 * Use appropriate technologies to make precise quantitative measurements and observations and to organize and analyze data.
 * Describe the flow of energy from the sun, throughout the earth system, living and non-living, from the cellular scale to the global scale, and describe the transformations of that energy as it moves through the system.
