On Monday 17th November, Dr. Sean Thurston, from the Royal Institution, was our guest scientist-in-residence. Sean is the L’Oréal Young Scientist Centre Technical Coordinator and is also project manager of the RI’s Crystallography Collection. He came in to the lab to help year 5 children answer questions they had about ice, crystals and changing state.
Amber had this to say…I thought that it was a great idea to have a scientist in residence visit the school. He was a fantastic choice. Everyone that worked with Sean loved it!
We made our own salt crystals, and discovered why ice is slippery.
He showed us a picture of the biggest crystals. And he taught us that sometimes crystals, while they form, can change colour. We watched a piece of wire cut through the ice, then it froze over and, if the ice was smaller, Sean could have picked it up by the wire.

The thing I enjoyed the most was attempting to make our own ice crystals. Also, I enjoyed looking at all the things that he bought in, like the ice moulds and seeing the piece of wire going through the ice.
