MAD HATTER'S HAT

'Take some more tea', the March Hare said to Alice, very earnestly.
'I´ve had nothing yet', Alice replied in an offended tone, 'so I can't take more'.
'You mean you can't take less', said the Hatter: 'it's very easy to take more than nothing'.

A mad Tea-Party.

Aims:

The students will create their own design of a Mad Hatter Hat for Halloween.

Materials you need:

Pencil, compass, ruler.
Construction paper, cardboard or postal boxes for the frame.
Any material you can imagine to decorate your creation (color fabric, paints, cutouts from magazines,...whatever) BE CREATIVE!!!!!
Scissors.
Glue stick.

Steps:

Follow the instructions to build the frame.

Making the brim:

On a piece of cardboard or thick paper, poke a hole in the middle.
The dimensions of this hole should fit your head, so measure the outline of your head first, grab a compass and draw a circumference.

To find the radius of the circle, follow the next instructions. Don't forget to check your class notes about it.

You sometimes see the word 'circumference' to mean the curved line that goes around the circle. An accurate definition would be: “a curve, falt, closed line in which all its points are equidistant from another point called center” Other times it means the length of that line. And that is what we know, that length, the outline of our head. To find the radius we have to use this formula.

Perimeter of the circle= 2πr

The Perimeter of the circle (length of the circumference) relates to one of the most important mathematical constants, the Greek letter π (“pi”). Whose numerical value is

3.14159 26535 89793…. (you can use 3,14)

Now, trace a concentric circumference bigger than the first one. Two or more circles are said to be concentric if they have the sane centre

Finally, cut out the center and cut around the larger circle.

Making The truncated cone ring of the hat.

Get a piece of cardboard that is thin and flexible,and cut it into a truncated cone shape that tightly fits into the hole in the brim. Notice you must place it facing down. Make one inch slits all around both edges of the cone.

Follow the instructions below!

Fold the slit edge inward.

Spread glue about 1 inch all around the edsge of the brim you cut out in step1, and paste them.

Making the top of the hat.

Repeat again the steps in point 1 to get the circumference fron the perimeter of the circle and draw a circle big enough to cover the top of the hat.
You naw are finished building the hat and can move onto step 4- Finishing touches!

Finishing touches.

Tou have completed the basic structure of the hat. You can now paint it and/or add decorations to your liking to transform it in a real Mad Hatter's Hat.
