What is your target demographic age range? I actually used to play a few sciencey games growing up, and it probably had a lot to do with how I got here.
If it is for younger kids- how about a traveling host who can go to the Great Barrier Reef and help clean it? Then take care of endangered animals in Africa? Then recycle at home where she wakes up everyday? Compost gardening, and other good habits? I do like the idea of energy and water gauges to help show how bad some appliances can be. Maybe she can upgrade her ampliances to more energy efficient ones as she levels up?
Hope this helps!
