Variation of Traits in Pea Plants - Matching

Grade 3 - 3-LS3 Heredity: Inheritance and Variation of Traits
NGSS Disciplinary Core Ideas
LS3.A: Inheritance of Traits
•  Many characteristics of organisms are inherited from their parents. (3-LS3-1)
• Other characteristics result from individuals’ interactions with the environment, which can range from diet to learning. Many characteristics involve both inheritance and environment. (3-LS3-2)
LS3.B: Variation of Traits
• Different organisms vary in how they look and function because they have different inherited information. (3-LS3-1)
• The environment also affects the traits that an organism develops. (3-LS3-2)

 Performance Expectations Students who demonstrate understanding can:
3-LS4-2. 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. [Clarification Statement: Examples of cause and effect relationships could be plants that have larger thorns than other plants may be less likely to be eaten by predators; and, animals that have better camouflage coloration than other animals may be more likely to survive and therefore more likely to leave offspring.]

 3-LS4-3. Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all. [Clarification Statement: Examples of evidence could include needs and characteristics of the organisms and habitats involved. The organisms and their habitat make up a system in which the parts depend on each other.]
