the first article i'm thinking of editing is called Solar_panel if i choose this article i will be adding to its maintenance section and trying to put explanations of terms that someone new wouldnt understand.
the second article i am thinking about adding to is Hydroculture this is a very bare article only covering the basics of what hydroculture is, i would like of adding types of hydroculture and some history about where hydroculture came from.
the third article i am thinking of adding to is Electrochemical_reduction_of_carbon_dioxide this is a little differant then the other two, it is about a new technique to reduce carbon dioxide. i found an external link that is related to this article and i think i can add a history section and some applications.
