Light can pass through some objects and is blocked by others. Where the light is blocked we see shadows.
“Light,” in the Reggio Emilia Approach acknowledges light as a material children use, a language, a way for children to create new languages and possibilities.
Using the overhead projector, explore what makes a shadow and what doesn’t. We call an object transparent if we can clearly see through it. It lets most light pass through and doesn’t make much of a shadow. We call an object translucent if it lets some light through. We can’t see through a translucent object and it makes a pale shadow. We call an object opaque if it doesn’t let any light pass through. It makes a dark shadow.
Inquiry Questions: About Light and Shadow
- Where is the light coming from?
- How can we play with light?
- What happens when you move the light?
- Does the spot of light always look the same? Can you make it bigger or smaller?
- What happens if you put an object in the path of light?
- What is creating the shadow?
- Are all your shadows the same size and shape?
How are shadows made?
Does the light come through the blocks, beads etc ? Does it make a shadow on the wall?
