He scoops some water in his plastic measuring cup from the table to pour into the beige funnel. In the process of pouring he says: "Watch this one come out."
He is already anticipating where it will come out, so when he pours, he immediately looks to his right to the bottom of the bin on that side.
He steps off his stool and crouches down to watch the water come out of the hose.
At this point, something amazing happens, he starts to trace the paths of the two hoses with his eyes and his hands. He first traces the hose that has the water coming out. He realizes that there is a second hose. He points up at the black funnel and says that it goes around here...
...as he continues tracing the second hose with his hands and his eyes.
I will be taking a week off from my blog. I will be at the NAEYC national conference in Orlando this next week. If you are interested in hearing about building apparatus in and around the sensory table, I am on the docket for 8:00 Thursday morning.
