STEP 1: Take apart the toothbrushes - I will give you some tips but I think it is more fun if you figure it out on your own (read my last blog post about letting students struggle ;-)
- Here are some handy tools to use - my new favorite tool is PVC pipe cutters! It also helps if you recruit help, our school board president helped me dig 10 motors out yesterday.
- Break off the head, take the bottom off and cut away!
Once you have the motor out you can decide if you want to keep your other pieces and re-purpose those in your makerspace.
STEP 2: Create Scribble Bots - I first got the idea of scribble bots from the book, The Art of Tinkering
- I tweaked the supplies to use a swimming noodle instead of a strawberry basket container.
- We used 9 volt batteries because that is what I had and they were WAY too powerful (they were sparking and made the wires HOT so I'm toning down the volts (or I am working on adding a resistor to tone down the voltage)
Here are some pictures of the resulting Scribble Bots from the fourth/fifth grade multi-age class I worked with.
I will be building these with a first/second grade multi-age class tomorrow and a second/third grade class on Friday. I am also in the process of creating a hyperdoc to go with the lesson and will add it here when it is completed tomorrow before I use it.
