To do that, I choose the sensory table with a cardboard divider setup pictured below. The setup is basically a long cardboard sheet that spans two sensory tables down the middle with smaller panels inserted horizontally to create multiple spaces in which the children can choose to work.
To focus my observations even more, I choose to look at how children in this space examine the properties of one very specific material in this space, namely, feed corn.
One way the children examine the properties is to actually feel it with their hands. And that can take on a different energy and rhythm. The child below is using his hands in a back-and-forth motion to feel the corn both under and over his hands.
