Why Are the Rocks All Different

I have had an intensive period of developing up some TV concepts. Nothing particularly new and nothing I can blog about yet. I have gone back over some old ones and revitalised them and got excited about them all over again.
However all these concepts will take many people and a long time to realise. I decided I wanted to create something that I could do all by myself!
I have used some of my own photos and created an early science and maths book for young children (3-8 years) through Lulu.com This was a lot of fun. These are my favourite photos from those moments when I noticed an interesting pattern or play of light and now I have been able to use them to develop children's 'looking closely and thinking' a useful pre-reading skill to say nothing of the concepts introduced through the questions. The pictures are all from nature.
The book is for sharing and discussing with children and encouraging their observation, figuring out and pattern recognition. Here is an example image and text.
Can you see the spiral, the zigzags and the stripes?
