By now it was lunch time so off we went to Denham Country Park Visitors' Centre.  Those of us in Years 5 & 6 remember this from our Year 4 walk.
We changed out of our boots and enjoyed our well earned lunches.

Once finished there was just enough time for a game.

Mrs. Walker got us all back together and then we sat down in the Education Room.

We had three tasks to do.  
The first was to consider some of the remains 
that have been found in the quarry and try to date them.
