Rocking...

I don't know about you, but in my family rock collection is a favorite past-time. My boys simply LOVE collecting any type of rock they can find, so this book is really great for them. It not only provides a lot of information, but it can be read independently by my 7 year old, and helps both of them achieving some sort of organization in their ever-growing collection.

You can download this free book (in a .pdf file) here: The first book of rocks

Have fun!!!
