Year 6 have been investigating batteries this week and making them out of lemons, potatoes, salt water and soda solutions.  They discovered that the potato produced the highest voltage, but they think this was because the potatoes used were so much larger than the lemons.  They will definitely need to complete some further investigations to prove this theory. They were surprised that the 3 cells produced the same amount of voltage as an AA battery.

" Thumbs up for more experiments - we learn so much more."
