Any help with this would be much appreciated, as it's been slowly driving me insane.
In elementary school (c. mid 90s), the entire class read a sci-fi novel about a girl with coloured-skin (green or blue maybe ?) essentially deserted on a (dusty/not an abundance of life ?) planet (in a different system) with her guardian (I don't think it was the same species, may have been AI), and she performs scientific observations and research, and something major obviously happens in the book (I think at one point she is separated from her guardian) for the sake of plot development.
I feel like I may have not finished reading it, so my apologies for not being more help.
