I had the children tell me about each of their senses.
I then explained that we were only going to use our sense of touch
to identify the contents of the touch box.
I asked questions like, "can you find something round and soft using only your sense of touch?"
We also each got to touch a bashful fern.
In case you don't know, a bashful fern is a plant that closes up when you touch it's leaves.
It opens up again in a few minutes.
