The horizontal tube extends completely through the box between two of the vertical tubes. The slanted tube rests on one of the protruding sections of the horizontal tube and empties into a smaller sensory table.
Children will still pour down the vertical tubes.
And they will still survey exactly where it went.
With the addition of the horizontal tube, the children can work on a horizontal plane through the tube. That is a much different physical experience than pouring down the vertical tube.
That, of course, leads to more connections. Watch what happens at the other end.
The boy has stuffed his scoop into the slanted tube to catch the pellets sliding down the tube. As he watches the pellets race down the tube into his scoop, he can't help but let out a "woh" and "woh-oh". It turns into a screech when he removes the scoop and pellets come flooding out of the bottom of the tube. Here, it is interesting to note the role of the observer in this play. The girl on his right adds to the excitement with her screech, too. She has been watching the whole time and has picked up on the boy's excitement. Sometimes we overlook the role of the observer when we analyze children's play. An activity shared is more exciting and joyous.
Let me end this post with a new exploration of the vertical tubes that uses the scoops. One group jammed a plastic scoop into the top of one of the vertical tubes. My guess is that they were trying to plug it because they like to plug holes (Axiom #6 from the right-hand column of this blog.) The scoop did not fit completely into the tube, leaving a slit at the top, a slit to slide pellets into.
That is inventive enough, but it did not stop there. They took another scoop and jammed it into the bottom of the same tube. Now they had a small slit at the bottom for the pellets to exit. The pellets actually flew out like they were coming out of a hopper.
Because children have this innate drive to learn about the world around them and how it works, an open-ended apparatus like the Vertical Tubes in a Box gives them license to explore and experience the natural world, both physical and the social.
