Activities in this unit focus on factors that impact the equilibrium of an ecosystem such as the Blackland Prairies of Texas and analyze how human actions impact ecosystems over time.
Students will complete activities that focus on explaining and element's chemical and physical properties on the periodic table and what makes up an atom.
Enduring Understandings
Balance within systems is regulated by the interactions between biotic and abiotic factors.
A sustainable community is based on wise use of energy resources which impacts the quality of life.
Energy is transformed by the movement of molecules to maintain equilibrium within an environment.
