Opals can come in all different colours and sizes.
If you come across a Opal, here's a tip for
finding the best one!
Opals that have lots of red and colour in are rarer because they are more difficult  to find.

WELCOME!


Welcome to our new blog all about fossils, minerals and gems!

We would like to share information with you all about fabulous rocks. I am a member of Rockwatch and if you are interested in geology then you will enjoy being a member and this is the url to find out more http://www.rockwatch.org.uk/ .

One of my favourite fossils is the ammonite. Ammonites were marine animals and had a coiled external shell similar to the modern pearly nautilus.

The ammonite's shell was divided into chambers separated by strong walls known as septa. They probably lived in water up to 100 metres deep.

If you’d like to see a real ammonite ask me and I will bring one in for you to see, if you are not at my school then check out this picture of one!


 

 
What is geology?

Geology is the study of our planet, earth.

*How it was made
*What it is made of
*How it changed over time

Geologists make maps to tell us about the history of earth and help us find things like:

*Important minerals, such, as diamonds.
*Fuels like oils.
*Problems like earthquakes or floods.

The main feature were going to talk about is stones.
