Students know:
  • Young animals are very much, but not exactly, like their parents.
  • Plants are very much, but not exactly, like their parents.


Students are able to:
  • Use observations as evidence to identify similarities and differences between parents and offspring and between offspring and other members of the same species.


Students understand that:
  • Patterns can be used as evidence that individuals of the same kind of plant or animal are recognizable as similar but can also vary in many ways.
