  • Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants. (2-LS2-2)
  • Make observations of plants and animals to compare the diversity of life in different habitats. (2-LS4-1) Emphasis is on the diversity of living things in each of a variety of different habitats. Assessment does not include specific animal and plant names in specific habitats.

Critical Content

Content and Skills

*Power Standard Content

LS2.A: Interdependent Relationships in Ecosystems

  • Plants depend on water and light to grow. (2-LS2-1)
  • Plants depend on animals for pollination or to move their seeds around. (2-LS2-2)

ETS1.B: Developing Possible Solutions  

  • The shape and stability of structures of natural and designed objects are related to their functions. (2-LS2-2)
