Ask HN: Help my 11 year old sister not get put off of science

I'm an Electronic Engineer at a top US research school and I have an 11 year old sister (I'm 22). She is smart and quite good at math for her age and is a solid rational thinker. Unfortunately her teacher "finds science boring" and has somehow managed to instill this in her: I know she would enjoy science as a subject if she could see it from my perspective but I can't think of any appropriate videos / games / books to share with her (all the vsauce, veritasium, numberphile channels etc. are a bit too advanced for her)

Does anyone on HN know of any good videos / books that can help an 11 year old girl see how beautiful science and math can be?
