Construction
paper or thick white paper |
|
Something to
write with |
|
Scissors |
|
Paper clip, or
a brass fastener |
|
Drawing Compass,
or something round to trace |
|
|
Use the drawing
compass to make two circles - one that is 6 inches in diameter and one
that is 5 inches in diameter. Or trace around the edges of a small plate
and a slightly smaller cup or saucer. Cut the two circles out. |
|
Connect the centers
of both circles by poking holes in the middle and attaching the two circles
with a brass fastener or a paper clip. |
|
Then draw lines
to divide the circles into 26 pie-shaped sections. You'll need 13 lines.
It should look like a pizza cut into really thin slices! |
|
Write the alphabet
around the edge of the outside circle and around the edge of the inside
circle. Then turn the inside circle so its letters line up with different
letters on the outside circle. It should look something like this: |
|
|
Now you can write
in code! When you are writing words, look at the outside circle for the
letter you want, but write down the letter you see on the inside circle. |
|
Write you name
in code, and underneath it write a message in code. Trade with a friend.
If you can decode your friend's name, you should be able to decode the
message! |

|
Is it
hard or easy to decode your friend's message?
Can you think
of other ways to code languages?

about it!
