Geology - rock making!

Studying the Stone Age has led nicely onto geology.
My Mom came round to do some experiments with the children.

The equipment...
They learnt about the different types of rock; sedimentary, igneous and metamorphic.
They then went on to make different types of sedimentary rocks.
Starting with sandstone...

Moving onto limestone made by crushing shells and adding them to plaster of paris.

Then allowing them to set. The children also went on to make conglomerate rocks using pebbles and cement.


Using the gas to blow up a balloon.

Kiki will not be left out!
