Makey Makey Mania

These past few weeks we’ve been playing with our teacher (Mr Graffin’s) newest toy that’s called a makey makey. It’s really cool and it uses electrical circuits to work. First off there is a control panel that you plug into the computer with metal panels that you clip wires to and they have arrows and click and space and on the back it has letters. You clip the wires onto the control panel and then the other end into a conductor like a potato or carrot. You then clip another wire onto the “earth” panel and then attach the other end of the earth wire to yourself. When you touch the potato or carrot it controls the computer. This works by the control panel generating electrons that flow through the negative end of the control panel and then through the earth wire. It then flows  through your body because your body is made up of about 60% water which is a conductor. It then flows through your finger into the potato or carrot and since the potato is connected through the wire back to the control panel that is connected to the computer it controls the computer. -Jacqui
