Marzano Experimental Inquiry

In June during our Field Day, an interesting occurance happened. High in the sky was the most interesting, different rainbow that I've ever seen! It was linear and twisted like a rope. It was a great teaching moment! I had the kids describe what they were looking at, try to explain why this was happening, and generate a hypothesis of how it had occured.
What we knew: fine mist had been falling since early morning, thereby creating the rainbow.
What we didn't know: why the rainbow was in a twisted, linear configuration.
This created a lot of discussion (some thoughts not well thought out!), but good discussion and hypotheses. We later found out that a jet from Hill Field had crossed the path of the rainbow and distorted the clouds which made the rope-like appearance! Way cool, and a being-there experience!
