# Lesson 1 Activity 2 - Complex Adaptive Systems

In this activity, students will watch a PBS ScienceNOW video about complex adaptive systems called "Emergence" and reflect on whether or not various systems are complex adaptive systems. (Note: Complex adaptive systems are systems that have "emergent complexity" as described in the video.)

After reviewing the concepts in the video, we assess students' understanding by playing the game "Complex or Complicated." Here's a presentation file for running the Complex or Complicated activity. To play, simply ask which image represents a complicated system vs. a complex adaptive system and engage the students in discussion.

For each of the following examples, choose whether the example is a complex system or just a complicated system.

Reflection:

Is "Turn and Walk" an example of a complex adaptive system? Why or why not? Post your reflection in your portfolio in the section "Reflections->Complex Adaptive Systems" under the heading "Is Turn and Walk a Complex Adaptive System?"

- Watch the video on Emergence
- Review characteristics of complex adaptive systems
- Play "Complex or Complicated"
- Reflect on whether or not "Turn & Walk" is a complex adaptive system
