 No, because if the drawing or cut out is

d. What is different about printed text in the

mirror, can you read it?
 The text reverses left-to-right because
when you turn the paper towards the
mirror, YOU'VE reversed the writing left-
to-right. Then you just see a mirror
image of it.
e. What characteristic of light is explored in
your activity?


 Reflection because light bounces off an

object. If the surface is smooth and
shiny, like glass, water or polished metal,
the light will reflect at the same angle as
it hit the surface.
 f. How is light reflected using the mirror?
 The reflection process inverts each wave
back-to-front, which is why a reverse
image is observed.

Can we live without light? Why/Why not?

 It is unlikely, though, that an adult could die directly and exclusively from prolonged darkness. Most likely a person would
become ill and die from a range of chronic diseases caused by lack of sunshine, such as diabetes, high blood pressure, and
tuberculosis. So, yes, I would say that humans need sunlight to survive.
