Materials:
Matches
Lantern
Other objects
Instructions:
Gather the children in front of a wall and with the lantern projects the shadow of several objects.
Finally, project the shadow of a lit match and let them know that the flame has no shadow. Surely hallucinate.
Because it happens?
You can explain that shadows occur because bodies prevent the passage of light through them and that these objects are called opaque.
The flame allows the passage of light, like glass and other similar materials. They are called transparent or translucent depending on the amount of light they let pass.
