If I got rid of Ada Twist Scientist, I would fail my 5yo's keeper test.
We read the books after the series. Very enjoyable.
My daughter loves the books, she's on book 10 now. The book was a recommendation from the staff in our local bookstore, it was a few weeks later that I discovered they had a tv series and it's been a real enjoyment for her to see the characters in her head appear on screen.
