Rock Hunting Rocks!

3V continued their scientific study of rocks by making the most of a dry (if blustery!) afternoon outside in the school grounds.  The children were looking to see how many different kinds of rocks we have here at Swan Lane.  The results might well surprise you!

First, we reminded ourselves about the three main kinds of rocks: igneous, sedimentary and metamorphic.  We shared ideas as a class about how we might spot the different kinds of rocks, and looked again at some photographs of different varieties.  We wondered whether we would find any or all of them in the school grounds?

We found an astonishing array of different rocks within a few metres of our own classroom!  We found granite, chalk, mudstone, slate and quartz almost immediately, as well as a number of different rocks that were trickier to identify.  

We even found a fabulous fossil in one of the stones!

There were one or two red herrings though: we learnt that bricks and concrete aren't really rocks, even though they are hardwearing and often used in building.








Although this looks impressive, it's not really a rock.  



If you look closely, you can see a fossilised shell on this rock!
