Background Information

Living organisms reproduce offspring and go through life cycles. Some offspring may look similar to their parents, while others look very dissimilar to theirs. Immature organisms that look similar to their parents will share some, but not all traits with their parents. This may be observed in many types of plants and animals. Examining the similarities and differences assists in identification, grouping, and classification.

Performance Expectations

1-LS3-1 Heredity: Inheritance and Variation of Traits

Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents. 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. variation-traits
