A potato clock! How interesting. There were zinc and copper strips and wires and a digital clock.
Complete the circuit with alternating zinc-copper strips and the clock comes on.
We started with 2 potatoes because it said 'potato' clock on the box, then...
Fai came running with 2 pieces of ginger. that worked too. Then...
Banana and potato....
Tomatoes.....
Then we ventured into liquids - 2 plastic cups were provided. First up, Coca Cola...
Milk works too.
Water can be used as well.
On loan from an unschooling mom, we had a wonderful time with the science kit. Thank you S!
