Circulating Science Toys

Circulating toys can be challenging. How many parts is too many? What to do about replacements? What about propriety software?  I would not recommend kits like Lego Robotics WeDo or Mindstorms to go out of the building. First, the programming software is proprietary and second having all the parts is important to each of the pre-designed constructions. Sparkfun Inventor's Kit, an Arduino beginner's package, is also something I wouldn't circulate. The parts are very small (less than a penny in size), including 2 different color coded resistors that need up close examination to determine which is which. That being said, there are plenty of small reusable kits that can circulate without hassle to any departments.

As I write this, we have just bought Sphero, an already built "ball" robot that focuses on coding through free apps as our newest circulated STEM toy. We already have two successful STEM kits that circulate for 2 weeks and are holdable by patrons with a val…

Importance of Documentation

I just read about cognitive load theory, developed by John Sweller, a professor at New South Wales Australia.  It's the notion that people can only hold seven pieces of information in their heads at one time.

According to SLJ's "The Cognitive Connection," May 2015, recent research claims that we might be holding less, maybe 2 or 4 things (pg. 25).  With that in mind, I recently tried to recreate a "talking skull" with the Sparkfun Arduino kit that I made last Halloween (with hands on help from our local maker at the time). It was much easier said than done.

I thought I had taken detailed pictures of the breadboard layout but upon recreation, I was flummoxed. I completely forgot how to do this! I should have taken the shots from above and clearly labeled the wires. I also should have taken a photo of the entire thing. I had a few white wires, one from the PR motion sensor, another from the servo. Which was which?



So I shot a video, surely I shot up close o…
