Elecrical Engineering!

One of the dads (an electrical engineer) did a great morning of circuits and batteries, solar power, potatoes... fantastic time! Here the kids are completing circuits and using batteries for power.

YES! This really did work - it lit up a small light bulb. The potato became an electrochemical battery - by using copper pennies and the nails, the reaction was enough to light the bulb. Apparently it works even better with lemons.
When everything was done and everyone else went out to play...
and then when even that was done... Samuel spent at least an hour on his own and actually connected all three circuit boards and made every light and fan work at the same time!
Two scientists engrossed in activity!
Once Liam was done with the circuits he set to fixing broken toys.
