Author: Lisa R. Bobich

Area: Life Sciences

Grade Level: 6-7

Overview: This lesson focuses on building understanding of scientific classification and plant structures.

Builds on Fundamental Concept: Form & Function

NATIONAL SCIENCE CONTENT STANDARDS

Content Standard A: Science as Inquiry
• Abilities necessary to do scientific inquiry
• Understandings about scientific inquiry
Content Standard C: Life Science
• Structure and Function in Living Systems
o Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs. Each type of cell, tissue, and organ has a distinct structure and set of functions that serve the organism as a whole.
• Diversity and Adaptations of Organisms
o Millions of species of animals, plants, and microorganisms are alive today. Although different species might look dissimilar, the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry.
o Biological evolution accounts for the diversity of species developed through gradual processes over many generations. Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment.
• Regulation and Behavior
o An organism's behavior evolves through adaptation to its environment. How a species moves, obtains food, reproduces, and responds to danger are based in the species' evolutionary history.
