Chemistry Assembly - Year 5

Yesterday we enjoyed a science assembly run by Andrew and Iona from the University of Bath.

Yesterday we enjoyed a science assembly run by Andrew and Iona from the University of Bath.


First Andrew used tennis balls to show how particles in solids, liquids and gases move.
Next he poured liquid nitrogen on the floor (this was –198 degrees C– amazing!). It immediately vaporised into gas– I felt some on my ankle! He warned us that there would be a loud noise - and used the gas to pop a balloon. Then he used the super cool liquid, which is colder than anything in nature, to shrink 5 balloons and fit them in a bowl.
He froze some flowers so they crumbled, and a banana so he could smash it with a hammer. It smashed into little pieces like a plate of glass. It blew my mind!


Finally, Andrew used the liquid nitrogen to make vanilla ice cream from custard. He currently holds the World record for the shortest time to make ice cream. This time it took him about seventeen seconds!


It was a fantastic start to our science week!
