Energy Experiment: Lemon Battery

In year 4 we are working on a unit related to Energy. 

That's why we did an experiment called "Lemon Battery".

A lemon battery is a simple battery made for the purpose of education. We used a piece of zinc metal (such as a screw) and a piece of copper (such as a 5 cents penny) wich are inserted into a lemon.

A 4t curs estem treballant l'Energia.

Per això hem fet l'experiment anomenat "Bateria de llimones".

La bateria de llimones consisteix en una bateria simple utilitzada en el món educatiu. Per portar a terme l'experiment vam utilitzar una peça de zinc (un cargol galvanitzat) i una peça de cobre (una moneda de 5 cèntims) insertats en una llimona.
