Thinking in Structure and Function - Level 2 - Complex Structures
In this video Paul Andersen shows conceptual thinking in a mini-lesson on complex structures. Two examples are included in the video and two additional examples are included in the linked thinking slides.
TERMS
Complex structures - structures that consist of many different and connected parts
System - a set of components (e.g. things) working together
Parts - some but not all of something
Function - an activity or purpose for a thing
Relationship - interconnection between parts of a systemE
This progression is based on the Crosscutting Concept elements from the NRC document A Framework for K-12 Science Education. “Complex structures and systems can be visualized, modeled, and used to describe how their function depends on the relationships among its parts.”

In this video Paul Andersen explains how various techniques have been used for years to collect seafood. Commercial fishing has led to overfishing in certain areas and species due to the tragedy of the commons. An explanation of aquaculture and sustainable fish yield is also included.
