ESSENTIAL QUESTION

How do organisms, and populations of organisms, depend on their environmental interactions both with living and non living factors?

Intermediate - Science - Grade 6 - Unit 4
Matter and Energy in Organisms and Ecosystems
Students will complete activities that help them discover that the interactions among organisms in an ecosystem facilitate the flow of energy and cycling of matter and follow predictable patterns.
OVERVIEW Show All | Hide All | Top

Unit Description: This unit begins with an introduction of organisms and the flow of energy within an ecosystem. The unit then progresses to environmental changes such as constructive and destructive forces that affect the ecosystem, and the relationship between changes within the environment and how an organisms’ population will be altered. The unit will focus on the relationship between a changing environment and how the organisms’ population changes while attempting to achieve stability, and eventually equilibrium. The unit culminates in a performance assessment where the students are predicting how changes in an environment may (or may not) affect future populations within that environment. Changes in the environment can determine the survival of populations and the stability of ecosystems.
