Do you know what is oxidation?

It is a chemical reaction in which an atom loses one or more electrons to oxygen atoms. Last week the sixth grade children we did some amazing experiments about it and we checked that if you rub an apple with lemon it protects the interior part of the apple and it oxidizes slower. Moreover, we mixed hot water, yeast and sugar and we discovered that depending on the quantity of sugar you add, more or less carbon dioxide will expel this mixture. That happens because of its fermentation. We had a really good time learning it by practicing it!
