Missouri Learning Standards

MO.3.LS1. From Molecules to Organisms: Structure and Processes
3.LS1.A. Structure and Function
3.LS1.A.1. Construct an argument with evidence that in a particular ecosystem some organisms -- based on structural adaptations or behaviors -- 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.]
3.LS1.B. Growth and Development of Organisms
3.LS1.B.1. Develop a model to compare and contrast observations on the life cycle of different plants and animals. [Clarification Statement: Changes organisms go through during their life form a pattern.]
MO.3.LS3. Heredity: Inheritance and Variation of Traits
3.LS3.C. Adaptation
3.LS3.C.1. Construct an argument with evidence that in a particular ecosystem some organisms -- based on structural adaptations or behaviors -- can survive well, some survive less well, and some cannot. [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.]
