Science Chapter books for 7 year olds

[Loopylooni]

Hi,

Does anyone have any recs for science related (maybe adventure type) chapter books, ideally those that come in a box set for 7/8 year olds?

Cookie series by Konnie Huq
Izzy The Inventor
Leonora Bolt
The Incredible Adventures of Professor Branestawm

If you're happy to include space ones, the ones that start with George's secret key to the universe by Stephen and Lucy Hawking are really good.

Not fixtion, but Dara O'Brien has two books that are for kids the my DC really enjoyed around that age

My DS loved that series

I stumbled across your thread months later but if it's not too late I recommend the Secret Explorers, they're exactly what you're after and my son enjoyed them a lot.

Nicola Davies might be an author to look out for, if the science tends more towards zoology: https://www.booktrust.org.uk/authors/d/davies-nicola/
