Ada Twist, Scientist

Ada does not speak until she is three, and then she never stops asking "why." As her parents navigate her endless curiosity, they find themselves conducting experiments just to keep up. It is a wonderful way to validate the constant questioning of a preschooler.
Ada Twist, Scientist by Andrea Beaty is estimated to take about 10 minutes to read aloud (903 words, about 3 sentences a page), and it lands best with children aged 4-8.

Our review
The rhythmic repetition of the word "why" acts as a refrain that children will love to join in on. It turns a parent's daily exhaustion into a shared, playful scientific journey.
This is perfect for the inquisitive child who is constantly poking at the world to see how it works. The science vocabulary is authentic, making it a great way to introduce real concepts through play.
Before you buy it
At 903 words with real science vocabulary, this is best read after Rosie Revere rather than as a first Beaty book.

Questions parents ask
How long does it take to read Ada Twist, Scientist aloud?
About 10 minutes at an unhurried pace, including a standard allowance for page turns, pictures and participation, from a word count of 903. Stopping for a longer conversation on every page will add more time.
What age is Ada Twist, Scientist actually for?
Ages 4-8 in our testing, which is narrower than the publisher's range. With 3 sentences a page and vocabulary at 4 out of 5, it asks for that much attention span and no more.
Does Ada Twist, Scientist survive being read on repeat?
Yes. It survives a fortnight of nightly repeats, which is the real test.
Is Ada Twist, Scientist a good book for a child who will not sit still?
It helps that it rhymes, and it has a refrain a child can join in with. Those three features are what keep a wriggling toddler listening, far more than the subject matter does.
Will my child memorise Ada Twist, Scientist?
Probably, and fast. The book leans on a repeated refrain, and at 4 out of 5 for re-read tolerance it survives the nightly repeats that get a book memorised. Expect your child to chant the pattern back before they can actually read.
Can a beginning reader read Ada Twist, Scientist on their own?
Not yet. At vocabulary level 4 out of 5 and 3 sentences a page, it is a read-aloud book rather than a first solo read. Read it to them now, and hand it over in a year or two.
What themes does Ada Twist, Scientist cover?
We tag it with science, curiosity, questions, rhyme and experiments. Those are the threads that actually run through the book, not just the ones on the cover, which is how it earns its place on our themed lists rather than a keyword match.
