Science eureka

We also learned how to make our own electricity by using copper and zinc in acid solution. We were told to connect the meters onto the strips of metals that were in a beaker of acidic solution, and try all the different combinations of metal together, electiricty was produced, but the readings were all different.. Then were told to choose the two metals that generated the greatest difference of electricity, which were the copper which was - and the zinc which was a +. Then we connected the crococdile clips to both of them and put them back into the beaker of acidic solution, then we connected it to a led light bulb, and the light bulb glowed.
