In Washington State, our new Science Standards are based on 3 Cross Cutting Abilities (Systems, Inquiry, & Application) and 3 Domains of Science- Physical Science, Earth/Space Science, and Life Science.
I have observed that Systems Thinking is not well understood and not explicitly present in most science instructional materials. This is unfortunate because a solid understanding of Systems Thinking can be a powerful teaching tool and also helps students make connections as they learn complex science concepts.
The good news is that there are a lot of resources for learning about Systems. I have listed some of my favorites below:
Dr. Art’s Guide to Science- Art Sussman’s book and site provide an easily understood take on Systems Thinking
NSDL Science Literacy Map for Systems
Science for All Americans Online- Chapter 11 Systems
Questions to Ask about Systems- a great 1-pager from Project 2061
Washington State’s Science Standards- see how Systems thinking progresses from K-12
My School as a System- middle school lesson from Science NetLinks
The Bicycle as a System- middle school lesson from Science NetLinks
Cell as a System lesson

Is it a System? Formative Assessment Probe from Uncovering Student Ideas in Science Vol. 4 by Page Keeley. I use this probe often in PD sessions on Systems- uncovers initial understanding of systems and is a great “conversation starter”.

[...] Science NetLinks-Back to School Posted on August 6, 2010 by science_4_all Science NetLinks just posted some New Lessons: Skin Cancer 2: Types, Prevention, and Detection; Energy Resources and Trade-Offs; and Air Masses. You will also find a wonderful grade 6-8 lesson called My School as a System- this looks like a great way to start the year and integrate some systems thinking. [...]
