So, what do you do when you are trying to make a circuit and your batteries are dead? Well, you find an alternative source of power of course! When we sat down to put the circuit together this afternoon we did not expect the batteries to be out. We quickly put into action the new set of “Green” Snap Circuits that he got for Christmas to go with his original kit. *Note you can get these from Hobby Lobby with your 40% off coupon and save a LOT of money!!! We setup the crank and it worked! We then tried the solar powered battery and it worked as well, but that needs to be charged some more. This was a real big learning experience as they kids really seemed to realize that we could use other things than batteries to power things.
The circuit we setup sounds an alarm when it is switched on in addition to having a power source that works! We also experimented with replacing the switch with a fixed circuit and swapped out the alarm with a different music player.
