One day we laminated different loose parts (like glitter and tissue paper) and placed them on the overhead projector to serve as a provocation. The children loved this! They compared the actual image to the image projected and became fascinated with their shadows.
Children are making discoveries through light and shadow. This is provides visual sensory play for children. This was an opportunity for the children to explore familiar mediums in a somewhat unfamiliar setting. Even though shadow and light are not objects that can be picked up and handled, these experiences provide opportunities for investigation and exploration of how light and shadows move, bend, bounce and change in our physical world.
