Our entry is both a tech and baking project. We made some apple pies which can play the tune of an English nursery rhyme.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Programming the Tune.
I wrote a program in Scratch that plays "Sing a song of Sixpence". Here is a link: https://scratch.mit.edu/projects/55790110/
Step 2: Connecting the Touchboard
The touchboard is connected to a laptop via a USB cable. We used an Arduino sketch from a Codasign workshop organized by Bristol University(http://codasign.com/ )which allows the touchboard to act like a computer keyboard.
Our program uses these keys: Q,E,T and A
Step 3: Making the Pies
Here is our recipe:
-peel and chop a cooking apple and heat it in a saucepan on a low heat with a tiny pinch of sugar
-roll out some shortcrust pastry and cut into larger circles (for the shell) and smaller circles (for the lid)
-after 5 to 10 minutes, the apple should go a bit mushy. Spoon the filling into shells and add the lid
-crimp the edges with a fork and brush milk on top.
-bake for 15 to 20 minutes, until golden brown at 200C (400F)
Step 4: Connecting the Pies
Crocodile clips connect the electrodes on the touch board to the pies to trigger a different line from the song. By touching the pie, the crust and fruit filling is conductive and it makes an electrical connection.
Step 5: Lyrics to the Nursery Rhyme
Here are the the lyrics to the rhyme so that you can sing along.
Sing a song of Sixpence, a pocket full of rye,
Four and twenty blackbirds baked in a pie,
When the pie was opened, the birds began to sing,
Now wasn't that a dainty dish to set before the king.
We hope you liked our project.
