Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Materials and Processes That Shape A Planet: Cite evidence to demonstrate and explain that physical weathering and chemical weathering cause changes to Earth materials.
Describe the changes in materials caused by each of the chemical weathering processes listed: Rusting/tarnishing; Dissolving by acid rain.
Environmental Science: Students will use scientific skills and processes to explain the interactions of environmental factors (living and non-living) and analyze their impact from a local to a global perspective.
Environmental Issues: Recognize and explain that human-caused changes have consequences for Maryland's environment as well as for other places and future times.
Identify and describe that ecosystems can be impacted by human activities: Protection of the Chesapeake Bay watershed; Resource acquisition and use; Land use decisions (agriculture, mining, and development); Recycling; Use and disposal of toxic substances.
