Kids playing with this cool little circuits kit. Jacob started on experiment #2 putting a fan in series with a switch. We then experimented with adding a light in parallel and in series. Jacob explained why the fan was slower and light dimmer when together in series than alone. Pretty sure he understood why no current went through lightbulb when added in parallel.
Reuben of course started at experiment #49 which introduced a diode with led and two switches in parallel. Of course it would light the led when the switches were off which was counterintuitive to Reuben. Good circuit to explain parallel and series circuits. We then switched the direction of the diode to show it works, but I think that fell flat on Reuben.
Now we are building a reflection detector with a photo resistor. This one is tough :-)
Wish I had this in college!!!
