Systems Thinking Guides K-12 Overview Why use Systems Thinking? Systems is 20% of the MSP Which Systems? Big Idea: Physical Systems Systems thinking makes it possible to analyze and understand complex phenomena. Earth/Space Systems Living Systems Systems-Speak K-3 Systems-Speak 4-5 Parts & Wholes Subsystems & System Function of the Part Systems Predict Inputs & Outputs Functions & Predictions Systems-Speak 6-8 Systems-Speak 9-12 Inputs & Outputs Positive Feedback Boundaries & Flow Negative Feedback Open and Closed Systems Equilibrium A System is a group of interrelated parts through which matter , energy or information flow. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Mark Watrin ESD112 Science Coordinator mark.watrin@esd112.org Systems K-1; 2-3 Part Name all the parts Predict: What if a part is missing?
