Introduce ecosystems with this interactive presentation.
Notes/presentation cover key vocabulary (organism, community, population, habitat, etc.) and include a review question covering experimental design (variables, controls, etc.)
After the presentation ends, each student will be assigned one biome to research as an extension activity.

NGSS Standards covered in this ecosystems presentation:
MS-LS2-2 Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems. Emphasis is on predicting consistent patterns of interactions in different ecosystems in terms of the relationships among and between organisms and abiotic components of ecosystems. Examples of types of interactions could include competitive, predatory, and mutually beneficial.
MS-LS2-3 Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem. Emphasis is on describing the conservation of matter and flow of energy into and out of various ecosystems, and on defining the boundaries of the system. Assessment does not include the use of chemical reactions to describe the processes.
