Shadows are created when light falls on, and is blocked by, a surface. The size and position of a shadow can tell you about the source of the light.
A shadow is created when an object blocks light from falling on a surface.
An object’s shadow always appears on the opposite side from the light source.
Shadows change when the relative positions of the light source and the object change.
(When connected to the 2017 solar eclipse event) A solar eclipse occurs when the Moon passes directly between the Sun and the Earth, blocking the Sun’s light and casting a shadow on Earth.
