2. Do you know
what illusion is?
When we see things not
as they really are.
Have you ever seen any
optical illusions?
What illusions can you
see in your everyday life?
3. I can say that we meet
various mind puzzles in
our real life when our eyes
don’t always see the world
as it really is.
I want you to give some
examples of them:
4. When you stand on the
road and look far
forward it seems the
road narrows and then
turns to point.
5. Sometimes the wheels of
the car seems to spin
against the movement
because of the shape of
the spokes.
6. When you are in a train
and your train doesn’t
move , then the nearest
train starts its moving, it
seems that your own train
moves back.
7. Look at these pictures
of optical illusions.
What do you see
there?
What do we pay attention
to when we see the
picture at first ?
15. What do we pay attention
to when we see the
picture at first ?
Can you explain why ?
- The images are large
- They are in the foreground
- The images are accurate
and clear, real and bright.
16. When we first look at the
picture we can see one
thing but when we
continue to stare at it we
can see something else.

Have look at the
pictures and answer the
questions individually.
Then, in pairs, compare
your answers with your
partner and discuss.
