Makey Makey

I decided to recycle a post from early 2016. Scratch has changed, but the experience is the same. If you are looking for a fun activity with an elementary aged child, try this…

I recently got the Makey Makey out of the drawer to teach my 8 year old how to program using Scratch. She has had some experience using Blockly with her Dash robot by Wonder Workshop. She has also used Scratch Jr. for the iPad, but this is the first time programming for herself.

The program was simple, but the impact was great.

The program used the “when a key is pressed” event to play a note. Each key played a note in a song from my daughter’s song book she uses for her piano lessons. She had to know the keys and read the music just like when playing the piano. We wired the Makey Makey to match the program. She had to change the half notes (0.5 beat) to quarter notes (0.25 beat). That gave us the opportunity to talk about fractions and decimals.

When using the Makey Makey, you have to connect yourself to complete the circuit. This gave us the opportunity to talk about electrical circuits and why our large piano works.

We also had a problem solving opportunity. Two of the “keys” had aluminum foil touching. This made two notes play at once. We talked about why the aluminum works to conduct electricity and how the tape and cardboard kept the electricity from one key from connecting to another.

To finish our programming, she got to play her song and others. This was a quick 30 minute activity, but we both had a blast and she learned a great deal.
