We have been working on our projects for 1 week all the other classrooms got 2 weeks so we had to work really hard Mrs Pearson said we had to have them in 1 week early but its really good cause if you want to change your board you have lots of time to change it i did my sience project on lemon power and how it can power things and it worked i powered a LED light for over 3 hours and 30 minutes.it all works with copper and zinc you need copper wire and copper coins (10c coin) you need zinc nails and you have to make it like a battery one side has the zinc nail and the other side has the copper 10c coin when you join the wires to each lemon (need four lemons to power LED)
this works because the led is a low voltage light bulb and can run up to days with the right stuff and lemons. our other teacher Mrs Morris and she helped me with the board cause i ended up handing mine in late but i got it finished.
