Curriculum Resource Kit: Rocks
Rocks are everywhere, they cover the whole earth. It is the foundation of the surface we live in. So, we basically live on rocks. They can be a part of a 5000 old year old ancient pyramid to the cement we walk on under our feet as we take a stroll on the street or in the park.

Rock collecting is fun; the best thing about it is that you can do it anywhere. We can encourage children to look around the environment for interesting rocks. Or perhaps if you pick up some rocks and look at them carefully, you will find something interesting. Whether if it’s the texture, colour or shape. So start a collection of your favourite rocks or just a rock for yourself because everyone needs a rock. And...
