Knowledge and Skills Statement

Organisms and environments. The student knows that organisms undergo similar life processes and have structures that function to help them survive within their environments.

characteristic of an organism that is not passed on from parent to offspring, is not the result of DNA, and is a trait that develops over the course of the organism's life through interactions with its environment

the circumstances, objects, or conditions that surround an organism including abiotic (climate and soil) and biotic (living organisms) that act upon an organism or an ecological community and ultimately determine its form and survival

specific variation in the characteristics of organisms received from a parent or ancestor by genetic transmission

something arranged in a definite pattern of organization; the arrangement of particles or parts in a substance or body; the aggregate of elements of an entity in their relationships to each other

Summary: Students can observe the different variations between types of plants and animals. Many animals in the same species resemble their parents but are usually not identical. It is important to use age-appropriate vocabulary in a student's learning stage. Students should compare animals of the same species and look for similarities and differences. Ask students questions like, ""Why are they different?"" and ""What causes them to be alike?"" These characteristics are inherited by the offspring, causing them to look similar.
