I come from the sun and I carry all the colors of the rainbow.

SHADOW

Back

I am formed in places where all of the light doesn’t reach. Sometimes I am very dark, and sometimes only a little bit darker than what is around me. Sometimes I take a shape similar to something nearby.

MOON

Back

I don’t have my own light, but I shine brightly in the sky. You see me mostly at night, but sometimes I peek out during the daytime.

SUN

Back

I am a source of light. Light energy starts with me. Light waves move out from me and illuminate the area around me. You can see me but should never, ever look right at me.ssss

I am an extraordinary kind of energy, and I travel as tiny waves. I am very fast, but you cannot see me moving.
