We were also given the opportunity to ask questions about a miners work and about how rocks were formed.
Mr Challiner then set us a challenge to draw one of machines that was used in the mines of the Queens crown which houses the famous Cullinan Diamond.
Runners up were Zack Coates and Olivia Holt.
The winners were Joe Dale and Lucas Archer.
Thank you very much Mr Challiner for taking the time to come and talk to us.
