Disciplinary Core Ideas - S.2.LS.2.2.DCI:
LS2.A: Interdependent Relationships in Ecosystems •Animals depend on plants or other animals for food. •(NYSED) Some plants depend on animals for pollination and for dispersal of seeds from one location to another. ETS1.B: Developing Possible Solutions •(NYSED) Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas to other people (secondary to 2-LS2-2)
