A non fiction book that is light (in kgs not in content!)

[onesparesecond]

DS is 7 and loves non fiction. He loves learning about anything and everything and telling us all about it. I'd like to get him a good one for our summer holidays but they are usually very heavy! Does anyone know of a good paperback one?

I think this is where Kindles and the like come into their own.

You are quite right. But I'm a little old fashioned!

Horrible Histories are quite light, but are probably a bit too old for him. There are Horrible Science books too if history isn’t his thing.
The I-Spy book are very small and are very informative. There are so many in the series. www.whsmith.co.uk/products/ispy-at-the-airport-what-can-you-spot/paperback/9780008182809.html
Perhaps get a magazine instead of a book. The best non-fiction children’s magazines are: National Geographic Kids, Horrible Histories, Owl and Discovery Box.
I’d also recommend the Little Scientists Big Questions collection.

Try the DK pocket eye witness books such as this one about inventions
