Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Find a Character to Use
1) Trace your character on a white piece of card stock using a sharpie (roughly the size of your cereal box) since I am no artist I used a character I found on the internet and projected the image on the wall to trace.
2) Color your picture
*Note: I used the character Moby from BrainPop
Step 2: Glue Your Picture to the Cereal Box
Step 3: Add "Organ" Holes
1) Take a pencil and outline where you are going to cut out the "organ" holes in your character.
2) Have an adult use the X-acto knife to cut out the shapes. (Make sure your holes are large enough to get your chopsticks in and pull the organ or random item out).
Step 4: Starting the "Motherboard"
1) Measure the interior of the cereal box you attached your character to in the previous step.
2) Carefully use the scissors to cut a new piece of cardboard just slightly smaller than the width and depth of the cereal box. This will serve as the "motherboard", where all the components of the game will attach to. You will connect the MaKey MaKey to it inside your cereal box.
Step 5: Completing the "Motherboard"
1) Place the "motherboard" inside the box and hold it so it is pressed to the underside of your picture.
2) Have a friend help you trace where the holes are located in your cereal box onto the "motherboard" (Label top and bottom)
3) Using the conductive paint: paint a line from the bottom of your "motherboard" to each of the shapes you traced.
4) Use the paint to also paint in each shape. Make sure and make a line at the bottom that connects all of the other lines.
Step 6: Making the "Motherboard"
1) Measure as many strips of cardboard as you have holes in your box. (I have 4)
2) You want the strips of cardboard to be equal in width to each other so the "motherboard" sits flat under the picture side of the box.
3) Use a glue stick to glue aluminum foil to these cardboard strips.
4) Bend the cardboard into the shape of the hole you traced on the "motherboard".
5) Use a hot glue gun to attach your cardboard and tinfoil “cups” to your "motherboard".
Step 7: Inserting the "Motherboard"
1) Insert the "motherboard" with the cups attached into the cereal box.
2) Measure the distance from the bottom of the motherboard to the inside of the box. You will need to cut strips of cardboard this width to elevate the motherboard so it sits against the underside of your picture in the box.
Step 8: Make Your Organs
1) Using modeling clay to make the organs/bones. You can also use random items, like a bottle cap or rubber band.
2) Make sure the clay or object fits nicely in the hole but allows room to grab the organ,bone,or item with chopsticks.
Step 9: Building Your Chopsticks
1) You can use a rubber band to turn your chopsticks into "tweezers".
2) Roll the paper in which the chopsticks were packaged and place the roll between the chopsticks.
3) Use a rubber band to secure the chopsticks with the paper between them.
Step 10: Making Your Chopsticks Interactive
1) Wind the copper wire around the chopsticks, starting at the base of chopstick all the way up to where your hand is.
2) Use a piece of aluminium foil at the base to secure the wire and to create a larger conductive surface at the end of your chopstick.
3) Clip an alligator clip to the “EARTH”on the Makey Makey and the other end onto the copper wire at the top of the chopsticks.
Step 11: Using Your MaKey MaKey With Your Operation Board
1) Attach another alligator clip to the conductive paint lead on the "motherboard", I suggest cutting a hole at the bottom of your cereal box for easy access. The alligator clip should be connected as shown above.
2) Connect the other end of the alligator clip to the “SPACE”section of the Makey Makey.
Step 12: Add the Code
Here is a picture of what your code might look like in Tynker.
