"Rosie Revere engineer" builds a scribbling machine
The story
The story
Where someone sees only a pile of garbage, Rosie Revere sees an inspiration. During the night, in her room, a timid Rosie builds fanciful inventions by recycling the junk she finds around. Hot dog vending machines, helium flying trousers, pecorino-based snake hats: every creation would leave the world speechless, if only Rosie would allow someone to see these creations. Instead, because of her fear of failure, Rosie hides her gadgets - and her dreams - under the bed. The story will be this until the day she receives a visit from the pro-aunt Rose, who teaches her a great lesson: a mistake is never something to be feared of, but rather a reason to celebrate, because making mistakes means learning.

I liked Rosie Revere immediately for my school projects thanks to the healthy inspiration it brings. We are in front of a little girl with dreams, with profound abilities, but who hides out of fear to make mistakes. I therefore believe that it is an excellent model to present at school to children and young people, as point of reference for inspiration.
The lesson of the pro-aunt Rose who says a mistake is a reason to celebrate, because making mistakes means to learn it, is for me a fundamental lesson in this society where we often forget how our story has evolved thanks to mistakes, but the worst part is when our children are denigrated for errors instead of accompanied in a path of acceptance of the error and of overcoming it.
Little Rosie Revere, with her ability to give new life to objects that others had lost meaning for, is perfect to introduce children to the world of tinkering.
Tinkering consists precisely in creating new objects using recycled materials that are also easily available at home, and maybe giving them a real soul with an electronic support.
Tinkering has origin in America in San Francisco at the Exploratorium where researchers have based this methodology based on experimentation and creativity, giving life to The Tinkering Studio. Book certainly useful is TheThe Art of Tinkering by Karen Wilkinson and Mike Petrich.
Objectives
Objectives
- Stimulate the aptitude to problem solving.
- Build and test a scribbling machine.
- Having confidence with electrical circuit.
Materials
Materials
- Plastic Cans of cheese for example
- Scissors, sheets, pencils, paper scotch
- DC motors
- Play-Doh
- Batteries 1.5V (one for each child)
- 4 markers for each child
- littleBits (if possible)
Activity
Activity
For Rosie Revere the activity I propose is building a scribbling machine, it means a machine that writes while walking. The scribbling machine is just one of the basic activities of tinkering.
The first thing to do is to attach 4 markers with the paper tape inside the plastic container. Above, on the other hand, the battery and motor will be positioned with the mobile part outside the surface. A cable of the scooter will be attached directly to the stack while for the other we will make a small switch with a paper tape to activate when necessary. On the mobile part of the motor we will put a ball of pongo. The weight of this put will allow the vibration of the container and therefore the writing with the markers. This is where the ability to solve problems comes out because if it doesn't work maybe you will have to enlarge or reduce the ball of pongo or move the markers. The motto is always the same, inventing, creating, testing, modifying!
The same work can be done with littleBits, do you know them? If the answer is negative you must do it!
These are small electronic modules that can be connected through the magnet and therefore allow you to build electrical circuits from simple to complex really easily!
They were designed by Ayah Bdeir, now founder and CEO of littleBits, of Lebanese origin, a woman of great creativity and entrepreneurial sense who after her Masters at the MIT Media Lab had the desire to invent something that could inspire girls to achieve and love his own scientific studies.
The modules have very bright colors also for this reason. The blue color represents the power, therefore the input, the green instead represents the output; the pink represents the modulators (a button to turn on and off for example), the orange instead represents the modules that can extend the circuit.
