Children's book base Story

For TSA, I shall be making a children's book based on a STEM topic; the topic I found a lot of joy in is flying. The basis for the story follows around a ten year old girl who lives in a flying house a little below the clouds (for reasons to make this sorta believable). The thing is the girl comes to find what she thought was magic keeping her house up is actually mix of physics and engineering similar to birds. She then figures if birds and her house can fly so can she then attempts to engineer a way to fly tackling it in a way many 10 year olds would from trying to make her own wing feather to trying some odd combination of cardboard boxes and wires until she can find an idea that works (process and elimination).
