1 - LS3 - Animal trait inheritance and variation - ASSIGNED (CJT 2/18/2014)

Module: Animal Trait Inheritance and Variation

DCI: LS3.A (A) Inheritance of Traits – Young animals are very much, but not exactly, like their parents.

DCI: LS3.B (A) Variation of Traits – Individuals of the same kind of animal are recognizable as similar but can also vary in many ways.

PE: 1-LS3-1 Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents.

 [Clarification Statement: Examples of patterns could include features plants or animals share. Examples of observations could include leaves from the same kind of plant are the same shape but can differ in size; and, a particular breed of dog looks like its parents but is not exactly the same.] [Assessment Boundary: Assessment does not include inheritance or animals that undergo metamorphosis or hybrids.]

The basic content of this standard seems to be as follows.

- Animal babies are like their parents, but not identical.

- Animals of the same kind are similar, but show variation.

THe PE suggests that kids need to use evidence to show that animal babies are like their parents.
