| We are having hands-on fun with circuits as I move through a free online Tinkering Fundamentals course by Exploratorium. The Scribbling Machine activity was a huge hit with Matthew and Malcolm!!
NGSS Science Standard: 4-PS3-4. Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
School Grade Level: 3-5  |
| First, we taped a motor and battery onto the bottom of a recyclable container. Next, we attached markers along its sides. |
 |
| After connecting the wires to the battery, the scribbling machine gyrated about the floor. Very cool! |
 |
| To offset the motor and alter the pattern of markings, we stuck weight to the end of the motor, such as a rubber eraser block or a glue melt stick. We tinkered around adding and taking away components and observing performance of the machine. |
 |
| Malcolm's all smiles, this is his favorite tinkering activity thus far! |
Update: I came across a similar activity on this website: www.Science Buddies.org. Here, you will find step by step instructions.
