With a few simple technology and art supplies, you can put together a simple kit that lets kids design and build bristle bots, art bots and light-up creatures.
The Science Behind the Fun: Hooking an unbalanced spinning toy motor to a brush sends vibrations through the bristles. The vibrating bristles move the brush, and anything attached to it, around on a flat surface. Make a disc robot by attaching toothbrushes to a CD and attaching a motor, or make a drawing robot with legs made of pens.
I’ve included ideas for items to put in a kit, along with a tech supply list and photos of the robots from STEAM Lab for Kids. Use your imagination for art supplies! Pair the kit with a book, like STEAM Lab for Kids (Amazon.com), which has instructions for making bristle bots, art bots and light-up creatures, or let tech-savvy kids take the reigns and start building!
LEDs, alligator clip test leads, toy motors and batteries let kids assemble simple circuits. (Supply list below photo)
Basic 3mm and 5mm through-hole LEDs (Art Bot, CD Bot, Light-Up Creature)
Small alligator clip test leads (Art Bot, CD Bot, Light-Up Creature)
AA battery holders (Art Bot, CD Bot )
AA batteries and 9V batteries (Art Bot, CD Bot )
9V battery clip snap-on connectors (battery snaps)
3V coin cell batteries (Light-Up Creature)
Mini electric motor for DIY toys (1500 rpm) for Art Bot, CD Bot
(Find these supplies at your favorite bricks and mortar location, like Axman Surplus stores, or get them online at Amazon.com or another tech retailer.)
Paper and plastic cups, brushes, toothbrushes, duct tape, zip-ties, and CDs all make great building supplies, and a glue gun always comes in handy.
Use your imagination for the art supplies.
And if you’ve got a kid who likes to sew, it’s fun to add supplies to make sewable circuits!
Sewable electronics: coin cell battery holders, sewable LEDs, snaps and conductive thread
Here are instructions for building a simple bristle bot.
Last week, the kids and I saw a bright red bird with a blue head. Baffled, I pulled out my favorite bird identification app: Merlin Bird ID, from the Cornell Lab of Ornithology. The app is free, available on the App Store and Google play, and much of the data in the app has been collected by citizen scientists, like you and me!
To use the app, you simply answer 5 simple questions about the bird you see and the app draws on a wealth of data to help you identify the bird. It comes up with a list of likely matches, and you choose the bird you’re looking at to learn more about it, and even listen to a recording of its song.
Normally, we can quickly identify the bird we’re stalking using the app, but the blue-headed red bird was tricky, so we went online to do more research. Merlin Bird ID suggested that it might be a cardinal, so we did a search for blue headed cardinals and discovered that we’d seen a bald-headed cardinal. It seems that some cardinals and blue jays molt all their head feathers at once, leaving their bluish skin exposed.
