My next series of science books called Curiosity Box will be published in the spring of 2016. It will feature items that children often collect on their walks in the countryside or along the sea shore.
These are the kind of items that eventually find themselves on bedroom window sills so the series is designed to re-examine them in a scientific way and build up an even larger data base. Curiosity is a precursor of scientific thought and this series is designed to help children think like a scientist.
Each week I will photograph an item from my own curiosity box collection (which at the moment resides with others on my study window) or from the countryside around my home.
Here is the first close-up of an object from my curiosity box. Can you guess what it is? I’ll post the answer on Friday afternoon.

Can you guess what’s in my curiosity box this week?
Did you get it? It’s a fossilised shark’s tooth!
