Please put together a few slides (Google Presentations is fairly ideal for this) to use as visual supports to you and your colleague(s) taking 10 minutes or so to explain this property to the rest of the class.
Ideas for how to use the time include:
pointing out the presence / absence of this property in Wes Anderson films
documenting the presence / absence of this property in other things that are situated in space
summarizing or even verbatim reading-out-loud of CA language for the property
comparing the description in the Grabow monograph to the descriptions in Battle For The Life and Beauty of the Earth and/or the descriptions in the 4-volume Nature of Order
Ideally you will be able to talk about the property as it operates at more than one scale.
Can't change a rubric once you've started using it.
In order to create video or audio recordings your computer needs to be
webcam-enabled. If you don't have a webcam on your computer, you can still
record audio-only messages by first installing the Google Video Chat
