One of the things I am enjoying most about my lunchtime Makerspace is the freedom that comes from exploration and playing with materials. One of the phrases I say a lot in both my classes or in my after school program, is "I don't know, let's try it and see what happens." An unfortunate consequence of the typical schooling that the majority of kids have received through the years is a fear of attempting something where the results are an unknown. In the Makerspace environment, freed from the confines and weight of the classroom agenda, I have been watching students take naturally to exploration. Which really shouldn't be a surprise.
I have been purchasing parts and supplies in small batches and some of the parts I had on hand at first were battery packs and small 1.5v motors. After working on soldering the switches and wires and battery packs for the glow bottles, a couple of students started exploring connecting switches, motors, and battery packs just to see what happens (but mostly because 6th and 7th grade boys like to make things move!)
So now there were new toys for the students to explore with, a spinning motor became a "drill" that was able to create patterns in a lump of conductive dough that had been left on the table. Then there were unintended results, soldering the wires from the battery pack directly to the motor makes for some very hot batteries and no way to turn it off.
So the result of "letting go" and allowing the students to tinker and play with these parts is where the learning takes place. Switches are something you might want to consider when designing a circuit, why do the batteries over heat when they are attached and then continually running the 1.5v motor, how can you measure the current that is flowing from one part to another and why is that important to be able to do sometimes, what are resisters and how might they be used.
We are planning to put the motors to use in some Beetle Bots this week, the rest of the parts arrive this week. I am looking forward to that.
