GRADE 3

Life Cycles and Traits


Plant and Animal Life Cycles
Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.


Inheritance and Variation of Traits
Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.


Environmental Influence on Traits
Use evidence to support the explanation that traits can be influenced by the environment.


Variation, Survival, and Reproduction
Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.
