This moves the conversation away from the desert as Will joins us at the table and picks up one of the spiders
This might be a spider. This needs much more legs. He counts the legs. 1,2,3,4,5,6. They have 8! It has 6. It needs 8. So I need this one, and this one. (Will chooses 2 more legs and adds them to the spider.) There. Eight legs!
As the children build their spiders they share their knowledge. Though much of what they say is inaccurate there is also much that is accurate: spiders have many legs, there are different kinds of spiders, tarantulas don’t live in Lincoln, the desert is a different environment with different inhabitants, 4 + 2 = 6. As adults we could just give the children the facts – spiders have eight legs, but if we wait the children may very well come up with that fact by themselves and others besides.
