How shadows are formed
As part of our science work we are investigating light and how shadows are formed. Elsie completed this work on shadows.
What is a shadow

What is a shadow?
A shadow is a dark area where light from a light source is blocked by a opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two- dimensional silhouette, or a reverse projection of the object blocking the light.
How Are Shadows formed?
Shadows are formed when an opaque object is placed in the path of light rays. An object through which no light can pass is known as opaque.
What do you need to make a shadow?
things are needed to make a shadow. The first is light. The second is something that blocks the light. Together, these two things make an area that is darker than what is around it. This area is called a shadow. Outside, people make shadows when they block light from the sun.
