Design and construct models to simulate how animals disperse seeds or pollinate plants (e.g., animals brushing fur against seed pods and seeds falling off in other areas, birds and bees extracting nectar from flowers and transferring pollen from one plant to another).*

Scientific and Engineering Practices

Developing and Using Models

Crosscutting Concepts

Structure and Function


Students know:
  • The structure of a plant.
  • The relevant structures of the animal.
  • The process of plant pollination.
  • The relationship between components of their model that allow for movement of pollen or seeds.
  • Relationships between the parts of the model they are developing and the parts of the animal they are simulating.


Students are able to:
  • Develop and use a simple model to simulate how animals disperse seeds.
  • Develop and use a simple model to simulate how animals pollinate plants.


Students understand that:
  • The shape and structure of plants and animals are designed to interact with their environment and function to disperse seeds or pollinate plants.
