The properties of rocks

In our Science lesson the children were carrying out various tests in order to find out the properties of a variety of rocks.
​
This test, using a pipette and water, will test whether a rock is permeable (allows water to pass through it) or impermeable (does not allow water to pass through it).
 
Some children used non-fiction books to research the properties of their rocks.
 
This test will let the children know how durable (hard wearing) their rock is as they scratch the surface of the rock with a dull pencil.
 
The children had to immerse their rock slowly in the water to test if their rock is high density (sinks) or low density (floats).
